New Online Slots: This Year’s Releases Ranked on Their Published Figures, and What Has Changed

New slots in five lines

• The year’s best on price. Top of the list is Gates of Olympus POP (96.54%). Big Bass Vegas 1000 and Eastern Fury share second place on 96.53%, and Gates of Olympus 2500 (96.51%) and Harvest Moon – Grave Profits (96.50%) complete the first five.
• Where to try them. Casinos licensed offshore, whose deposit packages open at £20 or €20. Because the terms name no games, check the lobby for the release before you pay anything in.
• The number to check. The RTP on screen. Hacksaw’s pair and Blueprint’s Fishin’ Frenzy release all list cheaper versions, and Max Win Machine’s bottom one roughly doubles a 30-minute try-out at 20p, from £1.87 to £3.87.
• The cheapest way to judge a new game. A small stake and enough spins. On our Spiky model the bonus round only becomes more likely than not after 160 spins, which at 20p is £32 of stakes.
• The catch. New does not mean better value. No 2026 default in our sources beats the 96.71% of the original 2020 Big Bass Bonanza, and Blueprint’s UK-only release starts at 95%.

Your plan for this week: pick one release from the table below, budget 160 spins at the smallest stake you enjoy, and stop there whatever happens. That is enough to learn how the game feels without paying to find out twice.

Play this if: the 2026 releases matched to your try-out

Each row pairs an aim with the release that serves it best on published figures. Costs are for a 30-minute try-out at 20p, which at the national average pace of about 496 spins an hour is 248 spins and £49.60 staked; the working is £49.60 times the share the game keeps.

Recommendation: if you want to see what 2026 has added, try one Pragmatic game for its mechanics and one Hacksaw game for its disclosure, on separate evenings, and keep the stake the same so the comparison is fair.

This year’s releases, ranked on what their providers publish

Nine 2026 releases in our fact sheet carry a published RTP. Here they are, highest default first; where two defaults tie, the newer release goes ahead.

Unranked: Play’n GO’s July to September 2026 release list puts no RTP or top prize beside Infernal Trinity, Viking Runecraft 1000, Moon Princess Extreme or Reactoonz Blitzways, noting only that Infernal Trinity debuted a new Play’n GO mechanic. Until figures appear, the info screen is your only source for those releases.

Now read the gaps. The six Pragmatic releases span 0.08 of a point, 96.46% to 96.54%, which is 4p on a 30-minute try-out at 20p, so choose among them on mechanics. The Hacksaw pair sit 0.32 of a point below the top, 15p more per try-out, in return for publishing everything. Blueprint’s release starts 1.54 points below the top and costs 76p more per try-out than Gates of Olympus POP.

Just before 2026

Two 2025 releases sit just outside the ranking. On 8 December 2025 Pragmatic released Big Bass Splash 1000, with a 96.52% default, money symbols as high as 1,000x and a 25,000x ceiling; on price it would land between Eastern Fury and Gates of Olympus 2500. Light & Wonder’s Rainbow Riches update, listed for the UK and EU on 16 July 2025, defaults to 96%, offers versions as low as 87% and stops at 520x.

Each new release in brief

1. Gates of Olympus POP (Pragmatic Play, 31 August 2026)

The Olympus theme on a compact 3×5 grid: 15 positions where the original has 30, six by five. Its multipliers go to 1,000x, and its jackpot prizes are given as multiples, the largest 25,000x. Its 96.54% default heads this year’s list in our sheet, though Pragmatic publishes no volatility rating or overall top prize for it.

2. Big Bass Vegas 1000 (Pragmatic Play, 24 September 2026)

Pragmatic’s newest fishing game is generous with free spins: three scatters bring 15, four bring 20 and five bring 25, in each case five more than the 2020 original gave. It adds red and blue fisherman wilds, and its money symbols reach 1,000x. Its default, 96.53%, is 0.18 of a point below the first Big Bass Bonanza’s; the Big Bass slots guide sets it against the rest of the series.

3. Eastern Fury (Pragmatic Play, 27 August 2026)

Built on a 5×5 grid, its signature is the fifth reel, where wilds expand and carry multipliers from 2x up to 100x. There is no earlier game to measure it against; the default is 96.53%.

4. Gates of Olympus 2500 (Pragmatic Play, 28 September 2026)

The final release in our sheet keeps the original six-by-five grid that pays anywhere and raises the multiplier cap to 2,500x: five times what the 2021 game offered and two and a half times Gates of Olympus 1000. Before the free spins, a wheel decides which of two modes you get. Default: 96.51%.

5. Harvest Moon – Grave Profits (Pragmatic Play, 13 August 2026)

Respins that collect money symbols are the centre of this one, with wilds multiplying by up to 1,000x, on a 96.50% default. The Pragmatic Play slots guide covers the provider’s other collect and grid games.

6. Helios – Triple Sun (Pragmatic Play, 14 September 2026)

Tumbling reels with as many as three modifiers. At 96.46% it has the lowest of the six Pragmatic defaults on this page, which makes a try-out 4p dearer than on POP.

7. Epic Ze Zeus (Hacksaw Gaming, 18 August 2026)

Hacksaw’s August headline: a 96.22% default with two cheaper versions (94.16% and 92.35%), the top score of 5 on the provider’s five-point volatility scale, and a 50,000x maximum, £10,000 from a single 20p spin. The only higher ceiling anywhere in our sources is Dead or Alive 2’s up to 100,000x, from 2019.

8. Max Win Machine (Hacksaw Gaming, 6 August 2026)

Released twelve days before Epic Ze Zeus, this line-paying game shares its 96.22% default and its 5/5 score, offers versions at 94.28% and 92.20%, and stops at 10,000x. Set the pair beside Hacksaw’s older Wanted Dead or a Wild (96.38%, 4/5, 12,500x): the new games are one step spikier, their defaults are 0.16 of a point lower, and their cheapest versions stop higher, at 92.20% and 92.35% rather than 88.42%.

9. Fishin’ Frenzy The Big Catch Gold Spins (Blueprint Gaming, page dated 29 January 2026)

Blueprint sells this 10-line spin-off in the UK only. Its ladder starts at 95% and steps down through 93% and 92% to 90%, and its maximum win is 2,500x. The original Fishin’ Frenzy starts at 96.12% and shares the 90% floor, so the UK version begins 1.12 points lower: on a 30-minute try-out at 20p, £2.48 against £1.92.

Play’n GO’s four, with no figures yet

Play’n GO’s summer list names Infernal Trinity, Viking Runecraft 1000, Moon Princess Extreme and Reactoonz Blitzways without an RTP, a volatility rating or a top prize for any of them. Viking Runecraft 1000 carries the same suffix as Pragmatic’s high-multiplier remakes, but nothing in the list explains what Play’n GO’s number refers to.

Sequel or new name: what each tells you before you spin

Four of the nine ranked releases build on a game you may already know, and five are new names. A sequel comes with a reference point, which helps when the provider publishes little.

The new names, Eastern Fury, Harvest Moon – Grave Profits, Helios – Triple Sun, Epic Ze Zeus and Max Win Machine, have no predecessor to lean on, although the two Hacksaw games can be set beside the studio’s own Wanted Dead or a Wild. Two patterns stand out. The Olympus sequels kept their original’s price, within 0.04 of a point. The two fishing sequels both start lower than the game they follow, by 0.18 and 1.12 points.

The planner’s rule that follows: with a sequel, compare its default with the original before you play, and walk away if the new one is dearer for no feature you want; with a new name, rely on the info screen and give it the full try-out described below.

Where to try them: the welcome offers, the lobby and the terms

In October 2026 the welcome offers are offshore casinos. Their licences were issued in Anjouan, Costa Rica and Curaçao; the Gambling Commission licenses none of them, and Gamstop Online covers none. The terms set out the licence, the ways the cashier takes payment and the full conditions. A welcome at this end of the market needs a deposit: the minimum is £20 or €20, the play-through runs from 35x to 40x, and the free spins, between 150 and 500, come in instalments with later deposits. The shapes vary: a 300% total built over three deposits, with no single deposit matched at 300%; a 200% match on the first deposit; matches spread over five deposits in places; and a free bet somewhere. Some terms say spin winnings arrive as cash, and documents are wanted everywhere before the first withdrawal.

A 2026 launch date sometimes appears in the terms. A new casino and a new slot share a problem: neither has a track record yet. If you combine them, read the terms twice, upload your documents on the first day and keep the first deposit at the minimum.

Because the terms never list games, the lobby search is part of choosing where to play. A release from late September may simply not be there yet; if it is missing, the release ranked next to it is usually a close match on price.

What wagering costs on a new game

If you clear a bonus on a new release, its RTP sets the bill. As an illustration, take a £30 bonus at 40x: £1,200 of play. At Gates of Olympus POP’s 96.54% the average cost is £1,200 × 3.46% = £41.52; at Max Win Machine’s 92.20% bottom rung it is £1,200 × 7.8% = £93.60. Bonus terms often list games that do not count, so check before you plan. Packages for slot players are compared in slots sign-up offers.

How long to give a new game before judging it

A new slot’s pay table is not public, so you learn it by playing, and the bonus round is what you most need to see. The question is how many spins that takes. Our model slots give a fair range, from the low-volatility Steady to the high-volatility Spiky, though Hacksaw’s 5 out of 5 games sit beyond even Spiky.

The curve flattens slowly. On Spiky the chance reaches 58.2% at 200 spins and 82.5% at 400; Book-style gets to 85.2%, Classic to 91.9% and Steady to 97.4% over the same 400. These figures come from each model’s average gap between bonus rounds (110, 160, 175, 210 and 230 spins), worked as 1 − (1 − 1/N) to the power of the spins.

What a 50-spin taster at 20p actually returns

Many people judge a new game on a quick taster. We simulated exactly that: 50 spins at 20p, £10 staked, 250,000 tasters per model, each with enough money to finish.

Every model averaged close to its RTP, £9.61 to £9.70, but the middle taster on Book-style returned less than half the stake. A short taster on a volatile game mostly shows you the base game, while a large share of the payback waits in the feature. Judge it on that and you will usually judge it harshly; chase the bonus beyond your plan and you will usually pay for the privilege.

What a 160-spin try-out costs at your stake

So the try-out worth planning is about 160 spins for any game rated high or above. At the national pace that takes about 19 minutes (124 spins per 15 minutes); at the fastest licensed pace, one spin every 2.5 seconds, it takes 6 minutes 40 seconds. Here is what it costs on average at four stakes, on the cheapest and dearest defaults of the year and on Max Win Machine’s bottom rung:

The average cost is small next to what you need to bring: a 160-spin try-out at 20p needs £32 in the balance to be sure of every spin, even though it costs about a pound on average. Pick the stake that makes the full 160 affordable (at 10p that is £16), and stop at 160 even if the bonus has not landed. For shorter, phone-length sessions, the mobile slots guide works through the same sums. The calculator opens on a 30-minute try-out at 20p on Gates of Olympus POP’s 96.54%.

What is really new: four trends in the figures

1. Ceilings climb inside each series

Each new generation in a series tends to lift the top, and the jumps are large:

Between those end points, the Big Bass ceiling stepped up through 4,000x (Bigger Bass Bonanza), 5,000x (Big Bass Splash), 10,000x (three releases from October 2022) and 20,000x (Big Bass Bonanza 1000). Yet the highest ceiling in our sources is older than all of them: Dead or Alive 2’s up to 100,000x, from 2019, twice anything launched this year. And no provider publishes how often its top prize is actually paid.

2. The number in the name

Pragmatic uses the number as a label for one feature. Gates of Olympus 1000 and Gates of Olympus 2500 are named after their top multiplier; Sweet Bonanza 1000 after its candy-bomb cap; Big Bass Bonanza 1000, Big Bass Splash 1000 and Big Bass Vegas 1000 after their highest money symbol. It is never the maximum win: Big Bass Bonanza 1000 can pay 20,000x and Gates of Olympus 1000 15,000x. Read the suffix as “this feature goes up to”, nothing more.

3. Default RTPs drift, then recover

Defaults are not fixed across a series either. Count the Big Bass releases with a published RTP: five at 96.70% or 96.71% (December 2020 to June 2022), then five at 96.07% (October 2022 to March 2024), then three at 96.51% to 96.53% (April 2025 onwards).

Turned into a 30-minute try-out at 20p, the three levels cost £1.63, £1.95 and £1.72 on average. The middle period made play about a fifth dearer, and the recovery undid most of that. Across all providers, 2026 defaults range from 95% to 96.54%, so on price alone a 2026 game is no clear step up or down from the ones already in the lobby.

4. Fewer figures, longer ladders, and “UK-only” labels

Disclosure is uneven. Of the nine ranked 2026 releases, two publish a volatility rating and three publish cheaper versions; the six Pragmatic releases give one RTP each and no overall top prize, and Play’n GO’s four give nothing in the release list. Where ladders are published, the bottom rung roughly doubles the bill: on a 30-minute try-out at 20p, Max Win Machine goes from £1.87 to £3.87, Epic Ze Zeus from £1.87 to £3.79 and The Big Catch Gold Spins from £2.48 to £4.96.

Market labels need care too. Blueprint’s UK-only Fishin’ Frenzy release defaults lower than the original, and Light & Wonder’s UK and EU version of Rainbow Riches runs as low as 87%. A UK label tells you where a game is sold, not that it pays more.

The British rules every new release must follow

A game launched this autumn at a licensed site arrives under the same rules as one from 2011. Five matter most for a new release:

• Speed and controls. Spins take 2.5 seconds or more, nothing spins on its own, and turbo, quick-spin and slam-stop buttons are banned, under design rules announced on 2 February 2021 and in force since 31 October 2021. That caps any new game at 1,440 spins an hour.
• No false wins. The same rules forbid sound or animation that celebrates a spin returning no more than its stake, and keep your net position and time played visible, however lively the new graphics.
• Stake limits. Spins are capped at £2 for players aged 18 to 24 (from 21 May 2025) and at £5 from 25 (from 9 April 2025), for online slots only. Epic Ze Zeus’s 50,000x is therefore worth £250,000 at most to a player of 25 or over, and £100,000 to someone aged 18 to 24.
• No bonus buys. In its warning of 17 January 2020 the Commission described a game that charged more than £3,000 to enter its feature; the six operators it contacted withdrew the option, and at licensed sites the bonus has to be triggered.
• Checks before a demo. Since 7 May 2019 nobody plays anything, free versions included, until age and identity are verified.

Two more apply to the money around the game: no reversing a withdrawal once requested (31 October 2021), and, since 19 January 2026, a 10x cap on bonus wagering and a ban on promotions that require two kinds of gambling.

Licensed sites: new names on established licences

New slots reach licensed sites through the same groups as old ones, and a brand that looks new may sit on a licence that is not. Nothing here says a brand carries any release on this page or runs any offer now.

BetMGM shows how a new name can sit on an old licence: when its British site opened in 2023, it ran on the licence and platform of LeoVegas, the MGM Resorts group that puts mobile first and also runs Bet UK. William Hill shows the opposite, an old name under a new owner: it joined evoke, the former 888 group, in 2022. evoke’s 888 Casino dates from 1997 and spent ten years advertising no-deposit spins; the group’s two largest penalties are £19.2m (William Hill, 2023) and £9.4m (888, 2022).

For how a series performs, Entain is the only operator with figures on record. Agreeing on 25 November 2025 to put the Big Bass games into over 2,700 of its Ladbrokes and Coral shops, the first major retail estate the series had entered, Entain said each title is a regular in its top 20 games for those two brands, and that Big Bass Splash did better than any other online slot it ran in the UK in 2025. Several Entain brands, Gala Casino and PartyCasino among them, share one account system, so expect one welcome across the group; Entain’s largest fine or settlement is £17m (2022).

Elsewhere the patterns hold whatever the release. Sky Vegas is Flutter’s casino-first brand and the one best known there for no-deposit spins. 32Red is casino-first within Kindred, now part of FDJ United, whose largest fine or settlement came to £7.1m in 2023. Jackpotjoy and Virgin Games run on Bally’s casual-games platform, where welcomes usually add extra play to a £10 deposit. PlayOJO and MrQ attach no wagering to bonuses. Dream Jackpot and Amazon Slots, Jumpman Gaming sites, open with a prize-wheel spin. bet365 (£582,120 in 2024) is led by its sportsbook, Betway (£11.6m in 2020) keeps sport and casino under one brand, and Genting Casino and Betfred (£3.25m in 2023) keep premises on the high street.

To check any brand, new or old, read its footer. Kwiff, LiveScore Bet and Hollywoodbets, for instance, give their licence holder and Gambling Commission account number there, which the public register will confirm. The new casino sites guide covers how to judge a fresh launch.

New offshore casinos: what a 2026 launch does not tell you

Offshore, the new games are the same, but the rules are not. A site without a British licence need not apply the 2.5-second minimum, the stake caps or the ban on autoplay and turbo, and nothing in British rules stops it from selling bonus buys on the Pragmatic releases above. Wagering is uncapped, which is why 35x to 40x is normal out here, and Gamstop and the British complaints process do not reach it.

New offshore names deserve the caution you would give a new game, and more. Kinghills and NineWin are recent launches from Curaçao companies that run sister sites; neither has a public record, and both are promoted in Britain through pages about avoiding Gamstop. Rainbet, licensed in Anjouan and run by RBGAMING N.V., is built for Bitcoin and other coins, which no licensed British cashier offers. Donbet and Goldenbet are two of the five Curaçao brands that Santeda International B.V. operates. All of them lack a British licence, so a complaint about any of them is beyond the Commission’s reach and the protections above do not apply.

Judge a new release in five minutes

1. Read the RTP (one minute). Compare it with the ranking table. For the Hacksaw pair and The Big Catch Gold Spins, a lower figure is a cheaper version that roughly doubles the cost at the bottom.
2. Look for the volatility and top prize (one minute). If the pay table gives neither, assume the game is at least as bumpy as our Book-style model until you see otherwise.
3. Look for a buy button (thirty seconds). A button that sells the bonus round means you are not at a site applying British rules.
4. Set the try-out (one minute). About 160 spins for a high-volatility game; pick the stake that makes 160 spins affordable.
5. Write the stop rule (one minute). The balance at which you stop, win or lose, and the spin count. Then start.

Where the release figures come from

Release facts. Dates are the providers’ announcement dates; RTPs, versions, volatility ratings, top prizes and features come from providers’ pages and press releases, as logged in our October 2026 fact sheet. Blueprint’s game is dated by its listing page and Rainbow Riches by its UK and EU listing. If a provider is silent on a figure, so is this page.

Ranking. 2026 releases with a published RTP, ordered by default RTP, newer first on a tie. Ranking on the cheapest listed version gives the same order.

Arithmetic. A try-out is 30 minutes at 20p at about 496 spins an hour, the pace implied by the Gambling Commission’s average of 124 spins in 15 minutes for January to March 2026: 248 spins and £49.60 staked, with an average cost of £49.60 × (100% − RTP). The 160-spin try-out costs 160 × stake × (100% − RTP).

Model slots. Steady (low volatility, 96.2%), Classic (medium, 96.0%), Spiky (high, 95.9%, 10,000x), Book-style (built to Book of Dead’s 96.21% and 5,000x) and Bass-style (built to Big Bass Bonanza’s 96.71% and 2,100x). The bonus-round odds use each model’s average spins between rounds; the tasters are 250,000 simulated runs of 50 spins at 20p per model. They illustrate kinds of game, not any 2026 release, whose pay tables are not public.
