Why each fits

Avalon runs at medium volatility with a 96.01% RTP, sitting in a well-trodden sweet spot: wins arrive at a measured pace, and the 1,400x max win is built around the free spin bonus rather than requiring a base-game miracle. Players who find that rhythm satisfying and then go looking for games like Avalon are usually chasing the same combination: a classic reel format where wilds and scatters drive the bonus, moderate swing, and a realistic ceiling. The picks below are anchored to those dimensions, matching volatility band, comparable RTP territory, or a similar max-win order of magnitude.
Agent Jane Blonde comes from the same studio as Avalon, Games Global, and the two slots share the same medium volatility band and an almost matching RTP: 96.1% against Avalon's 96.01%. The mechanic is a standard 5-reel layout across 9 paylines, keeping the format in the same family as Avalon's winning-combo structure.
The clearest separation is the max win: x3421, notably above Avalon's 1,400x ceiling. For a player who finds Avalon's session rhythm comfortable but wants more headroom on a single spin, this is the natural next step within the same volatility band and provider stable.
ThunderStruck II is a Games Global slot running at medium volatility with an RTP of 96.65%, a slightly higher figure than Avalon's 96.01%. Players accustomed to Avalon's moderate swing will land in familiar territory on the volatility axis.
The structural difference is the mechanic: a 243-ways-to-win format replaces Avalon's standard payline structure, and the max win climbs to 8,000x, well above Avalon's 1,400x ceiling. Those two elements change the feel of each spin, but the volatility rhythm connecting the two slots is genuine and provider-consistent.
Chilli Heat from Pragmatic Play shares Avalon's medium volatility and posts an RTP of 96.5%, a slightly higher figure than Avalon's 96.01%. The 5-reel structure keeps the base-game format in the same general territory.
The key divergence is the bonus mechanic: the Hold and Win mode, triggered by cash symbols landing on the reels, replaces the scatter-and-multiplier free spin approach that powers Avalon's 1,400x ceiling. The max win sits at 2,512x, a higher ceiling than Avalon's, reached through a different bonus path. Players comfortable with Avalon's pace but open to a collect-mechanic bonus will find this a reasonable bridge.
Blood Suckers from NetEnt is a classic 5-reel slot with fixed paylines and a Vampire Slaying Bonus Game as its headline feature. Its low-medium volatility puts it one step below Avalon's medium on the swing scale, and its 900x max win is the nearest ceiling to Avalon's 1,400x among the alternatives listed here.
Where it stands apart most sharply is RTP: at 98%, the long-run return is notably higher than Avalon's 96.01%. For a player who values a max-win scale closest to Avalon's while accepting a slightly calmer volatility profile and a higher long-run return, this is the logical pick in the set.
Big Bass Secrets of the Golden Lake from Pragmatic Play uses a classic 5x3 reel layout with 10 paylines, a mechanic band that closely matches Avalon's standard left-to-right combo format. Its RTP of 96.07% is an almost matching figure to Avalon's 96.01%, the closest in this set of candidates.
The meaningful divergence is volatility: this slot runs at high, versus Avalon's medium. That step up brings a 5,000x max win, considerably above Avalon's 1,400x, but also longer dry patches between bonus triggers. Players who want Avalon's mechanic structure and RTP profile but are ready for higher variance will find it here.
Game of Thrones from Blueprint Gaming operates with 4,096 ways to win, a mechanical departure from Avalon's standard payline format. Its RTP sits at 94%, below Avalon's 96.01%, and volatility is high versus Avalon's medium, meaning fewer and larger wins replace the moderate-paced sessions Avalon delivers.
The draw for Avalon players is the max win: 17,000x positions this title well above the 1,400x ceiling, for players who have decided Avalon's top end is too conservative. The 4,096-ways mechanic and licensed property branding make it a different product in style, but for a reader benchmarking ceiling size against Avalon, it is the clearest escalation option in this set.
The Library from Kitsune Studios runs on a 5-reel fixed-payline setup and posts an RTP of 96.34%, a comparable figure to Avalon's 96.01%. Players who benchmark on long-run return will find the two close on that dimension.
The departures are volatility and mechanic: this title carries a volatility rating of 5 and includes a bonus buy feature absent from Avalon, giving players direct access to the bonus round rather than waiting for scatter triggers. For Avalon players who want a broadly similar RTP but are willing to accept higher variance and a bonus-buy option, this combination covers that preference.
Medusa's Mystic Reels Megaways from Playzia uses the Megaways engine, a fundamentally different mechanic from Avalon's standard winning-combo format: the number of symbols per reel changes each spin, creating a variable win-ways count that Avalon does not have. Its RTP is 94%, below Avalon's 96.01%, and its volatility rating of 5 places it above Avalon's medium band.
No verified max-win figure was available from the sources at the time of writing. This title is included for Avalon players curious about how the Megaways format changes session dynamics compared to Avalon's fixed reel structure, with the understanding that the mechanic, RTP, and volatility all sit in meaningfully different territory.
Across the eight alternatives, medium volatility is the most common thread tying candidates to Avalon. Agent Jane Blonde and ThunderStruck II share both the volatility band and the Games Global studio, making them the tightest mechanical siblings. Chilli Heat mirrors the medium volatility and lands in comparable RTP territory, though its Hold and Win mechanic shifts the session toward coin-collect rather than scatter-driven free spins. Blood Suckers sits just below at low-medium volatility, with a 900x max win that is the nearest ceiling to Avalon's 1,400x among the candidates listed. For players comfortable moving up the risk curve, Big Bass Secrets of the Golden Lake carries an almost matching RTP but steps into high volatility, and Game of Thrones lifts the max win to 17,000x. Slots like Avalon reward patience over high-variance swings, and the table below shows exactly where each alternative converges and diverges on that axis.
For the closest substitute, Agent Jane Blonde is the answer: same medium volatility, near-identical RTP to Avalon, same studio. Move to ThunderStruck II if the volatility match matters most and you are comfortable with a 243-ways mechanic and a higher max-win ceiling. Blood Suckers suits players who want a ceiling closer to Avalon's 1,400x alongside a notably higher RTP and a calmer swing. For those ready to trade Avalon's medium volatility for high variance and a much bigger ceiling, Big Bass Secrets of the Golden Lake or Game of Thrones cover that escalation. Players searching for games like Avalon primarily on RTP alignment will find Blood Suckers and Big Bass the closest figures, though the volatility trade-off in each case is real.
A casino game like Avalon earns a place on this list only when it shares a verifiable, fact-checked dimension with the head game: volatility band, RTP proximity, mechanic type (payline structure, wild behaviour, scatter-triggered bonus), or comparable max-win ceiling. Every figure cited in the reviews below is sourced from verified documentation. Alternatives with incomplete data appear with the caveat noted rather than a figure estimated. Thematic adjacency is flagged as a secondary consideration, not a primary ranking criterion.

Online slots are games of chance. Every spin is decided by a random number generator, and no system, staking pattern, or "hot" machine changes the odds in your favour. There is no skill or strategy that guarantees a win, and no way to make a game due to pay out. Slots are a form of entertainment, and the cost of that entertainment is the money you stake. Treat them as something you spend on for fun, not as a way to make money or to recover money you have already lost.
Decide what you can comfortably afford to lose before you play, and set that as a firm budget. Licensed operators give you tools to hold yourself to it: deposit limits, loss limits, time-outs, reality-check reminders, and self-exclusion. Turn these on at the start rather than in the heat of a session, when a limit is far easier to set than to respect. Playing within a fixed budget, with limits already in place, is the single most reliable way to keep slots enjoyable.
Watch for the signs that it has stopped being fun: chasing losses to win money back, playing longer or more often than you intended, betting money you cannot spare, or feeling anxious, secretive, or low about how much you are playing. If any of that sounds familiar, take a break and reach out. Free, confidential help and advice are available through GamCare and BeGambleAware, whose support is independent of any operator and available whether you gamble a little or a lot. Asking for help early is a sign of good judgement, not failure. This site and its content are strictly for adults aged 18 and over.
