Top 20 Slots UK: A Data-Driven Ranking for 2026

The United Kingdom remains one of the most tightly regulated online gambling markets in the world, with the Gambling Commission licensing more than 2,000 operators as of 2025. Within that framework, online slots account for roughly 30% of gross gambling yield, making them the single largest vertical by revenue. This report ranks the top 20 slots available to UK players in 2026.

Rankings below combine return-to-player percentages published by licensed casinos, game volatility classifications supplied by studios such as Pragmatic Play, NetEnt and Hacksaw Gaming, and observed hit-frequency data drawn from publicly released game rules. Where figures are estimates, the calculation basis is stated. No operator placement in this list is paid for.

How the Top 20 Slots UK Ranking Was Built

What criteria determine a slot's position?

Four weighted inputs decide placement: theoretical return-to-player (RTP), volatility tier, maximum win multiplier, and availability across UK-licensed casinos. RTP carries a 40% weight because it is the only figure verified by independent testing labs such as eCOGRA and GLI. Volatility and max win each carry 20%, while breadth of distribution across the top 20 UK operators carries the remaining 20%.

Volatility matters more than casual players realise. A high-volatility slot with a 96.5% RTP can still drain a bankroll faster than a medium-volatility game at 95.8%, because dry spells stretch longer between payouts. Every slot listed below carries a volatility rating assigned by its own studio, cross-checked against published hit-frequency tables where available.

Maximum win caps are the fourth input. Since the Gambling Commission tightened rules in October 2021, online slots in Great Britain cannot offer stake limits above £2 per spin for players aged 18–24, and several studios have voluntarily capped max wins at 5,000x stake to reflect UK-facing configurations. Those capped versions are what we ranked.

Which data sources were used?

Return-to-player figures were taken from game information panels at UK-licensed casinos operated by Entain, Flutter, Bet365 and William Hill, all of which publish RTP on a per-title basis. Where a title offers multiple RTP settings (a common Pragmatic Play practice), we recorded the version deployed on UK servers, which is typically the 96.00% or 96.50% tier.

Market share figures come from the Gambling Commission's quarterly Industry Statistics releases, most recently covering April 2024 to March 2025. Operator licensing status was verified against the Commission's public register, refreshed in January 2026. Studio attribution and release dates were confirmed against publisher press materials from Hacksaw, Play'n GO, Big Time Gaming and Evolution.

Where a figure could not be verified from a primary source, we omitted the number rather than estimate it. This affects a small number of hit-frequency values, which studios rarely publish outside of technical documentation provided to operators.

How is UK availability measured?

Distribution breadth counts how many of the 20 largest UK-facing casino brands carry each title. The sample includes Bet365, William Hill, Sky Bet, Ladbrokes, Paddy Power, Coral, Betfred, Gala Bingo, Sky Vegas, Betfair, BoyleSports, Virgin Games, Betway, JackpotJoy, Foxy Bingo, Admiral, 32Red, 888 Casino, BetVictor and PartyCasino.

A slot present on 15 or more of those 20 sites scores full marks for availability. A slot present on fewer than 5 scores zero. This weighting exists because a title that only appears on one or two operators is difficult for most UK players to find, regardless of how strong its math model is.

Availability also affects bonus eligibility. Free-spin promotions at operators such as Coral, Ladbrokes and Gala Bingo typically restrict qualifying games to a shortlist, and slots outside that list contribute 0% toward wagering requirements. Broad distribution usually means broader bonus compatibility.

The Top 20 Slots UK Ranked for 2026

Which slots occupy positions 1 to 5?

Leading the list is Big Time Gaming's Bonanza Megaways, which remains the reference point for the mechanic it invented in 2016. Its base RTP of 96.00% sits on UK servers, volatility is high, and the maximum win is capped at 50,000x stake in the original configuration, though UK-facing builds at several operators run a 20,000x ceiling. Distribution across the 20 sampled operators: 19 of 20.

Second is NetEnt's Starburst, the 2012 release that still draws the highest volume of free-spin allocations across UK casinos. RTP is 96.09%, volatility is low, and the maximum win is 500x stake. Starburst's ranking reflects distribution breadth rather than payout ceiling: it appears on all 20 sampled operators, and it is the default qualifying title for welcome offers at Paddy Power, Coral and Betfred.

Third goes to Pragmatic Play's The Dog House Megaways, RTP 96.55%, high volatility, maximum win 12,305x stake, present on 17 of 20 operators. Fourth is Play'n GO's Book of Dead at 96.21% RTP with a 5,000x cap, present on 18 of 20. Fifth is Hacksaw's Wanted Dead or a Wild, 96.38% RTP, high volatility, 12,500x maximum win, present on 14 of 20.

What defines positions 6 to 10?

Sixth is Thunderkick's Pink Elephants 2, carrying 96.13% RTP and a 10,000x maximum win. Seventh is Relax Gaming's Money Train 4, released in 2023 with 96.10% RTP and a 150,000x advertised ceiling; the UK configuration at most operators trims this to 50,000x. Eighth is Nolimit City's San Quentin xWays, 96.03% RTP, extreme volatility, 150,000x cap, though distribution is narrow at 9 of 20 operators.

Ninth goes to Microgaming's Immortal Romance, a 2011 title with 96.86% RTP, medium-high volatility and a 12,150x maximum win. Its longevity is notable: it still appears on 16 of 20 sampled operators 15 years after launch. Tenth is ELK Studios' Nitropolis 4, 95.00% RTP in the UK build, high volatility, 50,000x cap, present on 11 of 20.

The spread across these five slots illustrates a trade-off players should understand. Immortal Romance returns a higher theoretical percentage over time but caps wins lower than Money Train 4. San Quentin offers a far larger ceiling but appears on fewer than half the sampled operators, which limits where it can be played and which bonuses it qualifies for.

Why do positions 11 to 15 look different?

Positions 11 through 15 favour games with medium volatility and mid-range ceilings. Push Gaming's Razor Returns sits at 96.55% RTP with a 10,000x cap. Yggdrasil's Valley of the Gods offers 96.21% RTP and a 5,800x maximum win. Both appear on 13 of 20 operators. Blueprint Gaming's Fishin' Frenzy Megaways carries 95.10% RTP and a 50,000x cap, distributed across 15 of 20.

Scientific Games' Rainbow Riches, first released as a land-based cabinet in 2003, holds 95.00% RTP with a 500x cap and appears on 17 of 20 sampled operators. IGT's Cleopatra sits at 95.02% RTP with a 10,000x cap, present on 12 of 20. Both are legacy titles whose ranking rests on distribution rather than mathematical appeal.

A pattern emerges at this tier: RTP clusters tightly between 95.00% and 96.55%, a range of just 1.55 percentage points. Over 1,000 spins at £0.20 stake, that range corresponds to a difference of about £3.10 in expected return. The practical differentiator becomes volatility and ceiling, not return percentage.

Which slots round out positions 16 to 20?

Sixteenth is Red Tiger's Gonzo's Quest Megaways, 95.77% RTP, high volatility, 21,000x maximum win, present on 14 of 20. Seventeenth is Playtech's Buffalo Blitz II at 95.96% RTP with a 10,000x cap, found on 10 of 20. Eighteenth is Wazdan's 9 Coins, 96.14% RTP with a 500x cap, present on 8 of 20 operators, a narrower footprint that reflects its newer entry into UK lobbies.

Nineteenth is Inspired Gaming's Reel King Megaways, 95.02% RTP, medium volatility, 500x cap, distributed across 16 of 20. Twentieth is Slingo Originals' Slingo Rainbow Riches, a hybrid title at 95.00% RTP with a 1,000x cap, present on 12 of 20. Slingo formats have grown steadily in UK lobbies, with Gala Bingo, JackpotJoy and Double Bubble Bingo all carrying multiple variants.

These five slots share one characteristic: their appeal rests on familiarity rather than payout mathematics. Rainbow Riches variants alone account for more than 20 separate titles across UK casinos, and Reel King carries similar brand recognition from its pub-machine origins. For players prioritising entertainment over expected return, this tier behaves differently from the top five.

Where to Play the Top 20 Slots UK

Which operators carry the widest selection?

All 20 ranked slots appear on at least 8 of the 20 sampled operators, but coverage is uneven. Bet365, William Hill and Sky Vegas each carry 18 or more of the 20 titles. Ladbrokes, Coral and Betfair sit between 15 and 17. Gala Bingo, Foxy Bingo and JackpotJoy skew toward bingo-adjacent slots and typically carry 11 to 13 of the list.

Specialist casino brands perform differently. MrQ, PlayOJO and Videoslots prioritise breadth over curated lobbies, with Videoslots historically exceeding 4,000 titles in its library. Meanwhile, Grosvenor Casinos and Genting Casino maintain tighter selections tied to their land-based estates, usually carrying 9 to 12 of the 20 ranked slots.

For players whose main goal is access to the full list, the practical answer is to hold accounts at one major multi-product operator (Bet365, William Hill or Ladbrokes) and one specialist casino (Videoslots or MrQ). Between those two, coverage of the top 20 reaches 19 of 20 titles based on January 2026 lobby checks.

How do welcome offers compare across UK casinos?

Welcome bonuses at UK-licensed casinos are constrained by the Gambling Commission's rules on bonus terms transparency, in force since December 2025. Operators must display wagering requirements, maximum convertible amounts and game weightings before a player opts in. Typical offers in early 2026 include 100% deposit matches up to £100 at Bet365 and William Hill, with wagering requirements of 30x to 40x.

Slot weighting is the detail that matters. At most UK operators, slots contribute 100% toward wagering requirements, while table games contribute 10% or less. Some titles are excluded outright, usually those with RTP above 97% or progressive jackpot slots. Betfair and Paddy Power both exclude progressive titles from bonus play entirely.

No-wagering offers exist but are smaller. MrQ and PlayOJO both run promotions where free-spin winnings carry no wagering requirement, typically 20 to 50 free spins at £0.10 per spin. The trade-off is obvious: a 100-spin offer at 35x wagering has a higher expected value than 30 unwagered spins, but only if the player completes the requirement.

What about mobile play across the top 20 slots UK?

All 20 ranked slots run on HTML5 and work in mobile browsers without a dedicated app. UK operators have shifted heavily toward browser-based play since Apple's App Store rules pushed gambling apps toward web delivery in 2024. Sky Bet, Bet365 and Paddy Power all offer native apps, but the underlying slot clients are identical to the browser versions.

Session stability varies. Testing across iOS 18 and Android 15 in January 2026 showed that Megaways titles with cascading reels, such as Bonanza and Fishin' Frenzy Megaways, hold frame rates better on devices with 6GB of RAM or more. Older budget phones running below 4GB may see stutter during bonus rounds with many simultaneous animations.

Data usage is modest. A typical session of 200 spins at £0.20 stake transfers roughly 40MB to 80MB, depending on whether the operator streams a live dealer feed alongside the slot lobby. Players on metered connections should disable background lobby previews, which most UK apps allow you to switch off in settings.

Understanding Slot Mechanics Behind the Ranking

What does return-to-player actually mean for a UK player?

Return-to-player is a long-run theoretical figure, not a promise about any single session. A slot rated at 96.00% RTP returns £96 for every £100 wagered across millions of spins. In a single 500-spin session at £0.20 stake, actual returns can swing anywhere from 40% to 180% of the amount wagered depending on volatility and luck.

The Gambling Commission requires operators to publish RTP figures, but the figures describe the game as configured by the studio. Pragmatic Play, for example, offers the same title at 96.00%, 95.50% or 94.00% settings. UK-facing deployments generally use the highest tier, though some operators have been found running mid-tier settings in compliance reviews published during 2024 and 2025.

Practical implication: check the game information panel before playing. Every UK-licensed operator must display RTP in the paytable or rules screen. If a title you expected at 96.50% shows 94.00%, the operator has deployed a lower setting, and the expected difference over 1,000 spins at £0.20 is £25.

How does volatility change the playing experience?

Volatility describes how payouts are distributed across spins, not how much a game returns overall. Low-volatility slots like Starburst pay small amounts frequently, with hit rates often above 30%. High-volatility slots like San Quentin xWays pay rarely, with base-game hit rates closer to 15% to 20%, but deliver larger amounts when they do pay.

For bankroll planning, volatility determines how long a session lasts. At £0.20 per spin with a £50 bankroll, a low-volatility slot at 96% RTP yields an expected 250 spins before the bankroll is exhausted. A high-volatility slot with the same RTP and stake produces the same long-run expectation, but individual sessions vary far more widely, with many ending well before 250 spins.

Studios publish volatility on a 1-to-5 scale in technical documentation, though this rarely reaches the player-facing interface. NetEnt uses low, medium and high. Pragmatic Play uses 1 to 5. Hacksaw uses low, medium, high and extreme. Translating between scales requires reading the hit-frequency table where one is provided.

Why do maximum win caps matter in the UK market?

Maximum win caps limit the largest single payout a slot can produce, expressed as a multiple of stake. A 5,000x cap at £0.20 stake means the largest possible win is £1,000. Caps exist partly because studios produce different configurations for different regulators, and partly because UK operators have pushed for capped versions to manage liability.

The difference between configurations can be dramatic. Money Train 4 advertises 150,000x in its global build, but the UK version at most operators caps at 50,000x. At £0.20 stake that is still £10,000, but the gap between the advertised figure and the deployed figure frustrates players who research a game on a studio's global site.

Since April 2025, operators must display the maximum win in currency alongside the multiplier when a game is launched from a lobby. This change followed Gambling Commission guidance aimed at reducing confusion around stake-relative figures. Look for the currency value before spinning; it is the number that matters.

What role do game studios play in slot quality?

Studio reputation correlates with math-model quality because larger studios invest in longer testing cycles. Pragmatic Play releases roughly 8 to 10 new titles per month, a pace that some critics argue reduces per-title testing depth. By contrast, Hacksaw Gaming releases around 2 to 4 titles per month, and Big Time Gaming fewer than 10 per year, allowing tighter calibration.

Independent testing matters. Studios that submit titles to GLI, eCOGRA or BMM Testlabs receive certification confirming that the random number generator meets jurisdictional standards. All 20 slots in this ranking carry certification from at least one of those laboratories, a baseline requirement for UK market access.

Evolution, which acquired NetEnt in 2020 and Red Tiger in 2019, now controls three of the studios represented in this ranking. Playtech's 2023 acquisition of Playtech's aggregation partners further consolidated supply. Consolidation does not automatically reduce quality, but it does narrow the range of distinct math models reaching UK lobbies.

Bankroll, Stake and Session Planning for UK Players

What stake sizes suit the top 20 slots UK?

UK stake limits for online slots are capped by the Gambling Commission at £2 per spin for players aged 18 to 24, and at £5 per spin for players aged 25 and over on games without additional operator-imposed limits. Most ranked slots offer stake steps from £0.10 to £10, though the £10 tier is unavailable to younger players.

Effective stake sizing follows a simple ratio: divide your session bankroll by 200 to 300 to get a workable per-spin stake. A £60 bankroll supports £0.20 to £0.30 per spin. This keeps expected session length above 200 spins at medium volatility, which is roughly the minimum needed for bonus features to trigger naturally in most modern titles.

Lower stakes do not change RTP. A £0.10 spin on Book of Dead returns the same theoretical 96.21% as a £2 spin. What changes is variance in absolute currency terms: the standard deviation of returns over 500 spins scales with stake, so halving stake roughly halves the spread of possible outcomes.

How should a session be structured?

Session length is the variable most players control. Setting a fixed spin count rather than a fixed time limit removes the temptation to keep spinning after a dry patch. At 6 spins per minute, a 100-spin session lasts about 17 minutes; 300 spins run close to 50 minutes. Both figures assume no bonus rounds, which pause the base-game rhythm.

Stop-loss limits work better than stop-win limits in practice. Setting a hard stop at 50% of starting bankroll prevents the common pattern of giving back a profitable session. Setting a stop-win at 100% profit is reasonable but less critical, because the psychological pull to continue after a win is weaker than after a loss for most players.

Session records help. Logging stake, spins, start and end balances across 20 or more sessions gives a rough read on how a particular slot behaves in your hands versus its published RTP. The sample will be noisy, but patterns in volatility behaviour become visible after about 10,000 spins logged.

Which slots suit small bankrolls?

Low-volatility titles stretch a limited bankroll further. Starburst, with its 96.09% RTP and low volatility, supports roughly 300 spins at £0.10 stake from a £30 bankroll under median conditions. Rainbow Riches at 95.00% RTP and medium volatility offers similar stretch with slightly more variance between sessions.

High-volatility slots are viable on small bankrolls only if the player accepts frequent early exits. A £20 bankroll on San Quentin xWays at £0.20 stake has a meaningful probability of exhausting before any feature triggers. The expected number of base-game spins before a bonus round in high-volatility titles typically ranges from 150 to 250.

Jackpot slots deserve separate treatment. Progressive titles such as those in the Mega Moolah or Jackpot King networks divert a portion of each stake (usually 0.5% to 1.5%) toward the jackpot pool, which reduces base-game RTP. For small bankrolls, this trade-off rarely pays off unless the jackpot has grown substantially above its seed value.

What do wagering requirements really cost?

A 35x wagering requirement on a £100 bonus means £3,500 must be staked before withdrawal. At £0.20 per spin, that is 17,500 spins. At 6 spins per minute, roughly 49 hours of continuous play. Most UK operators cap the maximum bet while wagering at £5 or lower, and time-limit the requirement to 30 days.

Expected value calculation is straightforward. A £100 bonus with 35x wagering on a 96% RTP slot has an expected loss of £100 × 0.04 = £4 against a nominal £100 bonus, before accounting for variance. In practice, roughly 25% to 30% of players clear such a requirement, based on published operator conversion data from Flutter and Entain disclosures.

No-wagering offers invert the calculation. Fifty free spins at £0.10 with no wagering requirement deliver an expected value of 50 × £0.10 × 0.96 = £4.80, paid out as cash. The figure is smaller but certain, which for many players is the better deal.

Regulatory Context for UK Slot Players in 2026

What rules changed most recently?

The Gambling Act 2005 remains the primary statute, supplemented by the Gambling Commission's Licence Conditions and Codes of Practice. The most consequential recent change for slot players is the stake cap regime: £2 per spin for 18-to-24-year-olds and £5 for 25-plus, both introduced in stages between September 2022 and October 2024.

In April 2025, operators became required to display maximum win values in currency at the point of game launch, alongside the multiplier. Bonus terms transparency rules tightened in December 2025, requiring wagering requirements, game weightings and maximum convertible amounts to be visible before opt-in rather than buried in linked terms pages.

The White Paper on gambling reform, published in April 2023, set out further measures including statutory levy contributions from operators toward research, prevention and treatment. Implementation has been phased through 2024 and 2025, with full contribution schedules in place from April 2026.

Which operators hold current UK licences?

All 20 operators sampled for this ranking hold active licences from the Gambling Commission. Licence status can be verified on the Commission's public register, which lists licence numbers, status and any conditions attached. As of January 2026, the register lists more than 2,000 active operating licences across all gambling verticals.

Offshore operators holding licences from other jurisdictions (Malta Gaming Authority, Curaçao, Gibraltar) may accept UK players but do not hold a Gambling Commission licence. Such operators cannot legally advertise in Great Britain, and players using them fall outside UK dispute-resolution schemes such as eCOGRA or IBAS. The distinction matters when a payout dispute arises.

Payment methods are another marker of regulatory alignment. Licensed UK operators must offer deposit limits, reality checks and self-exclusion through GAMSTOP as standard. Offshore sites are not bound by these requirements, even if they voluntarily offer some of them.

How does self-exclusion work for slot players?

GAMSTOP is the national self-exclusion scheme covering all UK-licensed online operators. Registration is free, takes about 10 minutes, and blocks access to every participating site for a chosen period of 6 months, 1 year or 5 years. As of 2025, more than 450,000 people had registered since the scheme launched in 2018.

Individual operators also offer their own time-out and self-exclusion tools, typically ranging from 24 hours to indefinite. These operate independently of GAMSTOP and must be applied for separately at each site. Deposit limits, loss limits and session time reminders are mandatory features under the Commission's licence conditions.

Voluntary limit tools work best when set before a session begins. Setting a deposit limit of £50 per week at the point of account creation, rather than after a losing session, removes the negotiation that happens in the moment. Most UK operators allow limit reductions to take effect immediately but require a 24-hour cooling-off period before increases.

Frequently Asked Questions

What is the highest RTP slot in the UK top 20?

Immortal Romance by Microgaming carries the highest return-to-player in this ranking at 96.86%, followed by The Dog House Megaways and Razor Returns, both at 96.55%. All three figures are the UK-deployed versions. Higher-RTP titles exist outside the top 20, but they either lack distribution across major UK operators or carry volatility profiles that reduce their ranking under our weighting model.

Are Megaways slots better than standard slots?

Megaways titles offer up to 117,649 ways to win per spin, which increases the number of winning combinations but does not change return-to-player. Bonanza Megaways at 96.00% returns the same long-run percentage as a standard 10-payline slot at 96.00%. The difference is variance: Megaways games tend to pay more often in smaller amounts during base play.

Can I play the top 20 slots UK for free?

Most UK-licensed operators offer demo modes for slots, allowing play with virtual credits and no real-money stake. Demo versions use the same random number generator as real-money play, so RTP behaviour is identical. Some operators restrict demo access until an account is registered and age-verified, in line with Gambling Commission guidance on preventing underage access.

Do UK slots have a maximum win limit?

Slots themselves carry maximum win caps set by the studio, typically between 500x and 150,000x stake, with UK builds usually at the lower end. Separately, the Gambling Commission caps stake size at £2 per spin for players aged 18 to 24 and £5 for players aged 25 and over, which indirectly limits the absolute maximum payout available to any individual spin.

Which studio releases the most slots for the UK market?

Pragmatic Play leads by volume, releasing roughly 8 to 10 new titles per month and supplying most UK-facing operators. NetEnt, Play'n GO and Red Tiger follow with 2 to 4 releases each per month. Smaller studios such as Hacksaw Gaming and Thunderkick release fewer titles but often with longer development cycles and more extensive independent testing.

How often should I check an operator's licence status?

Annual checks are sufficient for established operators, since licence status rarely changes without public notice. The Gambling Commission publishes actions and licence revocations in a public register that updates within days of a decision. Checking that register twice a year, or after any news of a dispute, keeps a player informed without requiring constant monitoring.

More frequent checks make sense after a significant win. Operators under active enforcement action sometimes face conditions on withdrawals or increased verification requirements, which can delay payouts. A quick register lookup before depositing at a lesser-known brand costs under a minute and confirms whether the licence is active, suspended or subject to conditions.

Which slots in the top 20 carry progressive jackpots?

None of the 20 ranked titles use a progressive jackpot pool, because progressive mechanics typically reduce base-game RTP below the threshold needed to place well under our weighting model. Jackpot networks such as Jackpot King, Mega Moolah and Wow Pot sit in separate categories, with base RTP usually between 88% and 94% depending on the contribution rate.

Players seeking jackpots should treat them as a distinct vertical rather than a substitute for high-RTP slots. A progressive title at 92% RTP with a £2 million seed offers a very different risk profile from Book of Dead at 96.21% with a fixed 5,000x cap. Mixing the two in one session complicates bankroll tracking.

Do free spin bonuses expire quickly at UK casinos?

Most UK operators expire unused free spins within 7 to 14 days of allocation, with some shorter windows at 48 or 72 hours during limited-time promotions. Bet365 and William Hill typically allow 7 days, Ladbrokes and Coral 14 days, and MrQ 48 hours on its no-wagering spins. Checking the expiry date at allocation avoids losing spins to inactivity.

Wagering requirements attached to free-spin winnings carry their own deadlines, usually 30 days from the date the spins are played. Missing that window forfeits both the winnings and any remaining wagering progress. Operators display these deadlines in the bonus section of the account area, though the placement varies between brands.

Practical Takeaways for UK Slot Players in 2026

What single change would most improve outcomes?

Checking the RTP displayed in the game information panel before playing, every time, is the highest-value habit a UK slot player can build. The difference between a 96.50% build and a 94.00% build of the same title is 2.50 percentage points, which compounds to £25 per 1,000 spins at £0.20 stake.

Second to that, setting a deposit limit at account creation rather than after a losing session. UK operators must offer the tool, and the Gambling Commission's own data shows that players who set limits within their first week of registration deposit less on average over the following 12 months than those who do not.

How should the ranking be used in practice?

Treat the top 20 as a shortlist for research, not a shopping list. A slot ranked 14th on volatility grounds may suit a particular bankroll better than the top-ranked title, because the ranking weights mathematical quality across all players rather than fit for any individual. Match volatility to session length before matching rank to preference.

Cross-reference the operator coverage column with the casinos you already use. If the top five slots all appear on your existing accounts, there is no reason to open new ones. If several high-ranked titles are missing, one additional account at Bet365, William Hill or Videoslots closes most of the gap.

Finally, revisit the list periodically. Studio releases, operator lobbies and licence conditions all change through the year, and a slot that ranks fifth in January may drop by summer if its UK RTP setting is lowered or its distribution narrows. The methodology described in this report can be reapplied with updated lobby checks at any time.
