Atlantis Megaways: Pearl Respins, Fixed Prizes and Alternatives

Atlantis Megaways combines ReelPlay’s changing reel heights with held-prize Pearl Respins. Six scatters start three respins, and new scatters reset that counter. Its Mini, Minor, Major and Grand awards are fixed stake multiples. Hypernova Megaways shares the structure, while Atlantis 10K Ways uses a fixed layout.

Pros and Cons

Reviewed by Paul Stone
Published: September 2018 · Updated: July 2026

Pros

• The Pearl Jackpot Respins lock every chest and clam scatter in place and reset the respin counter to three on each new hit, so a busy trigger builds genuine tension as the grid slowly fills with coin values and jackpot symbols.
• Chest scatters each carry a visible 1x to 100x coin value during the respins, so you can watch your potential payout climb before the round even ends, a clearer reward signal than most respin features give you.
• Four fixed jackpots (Mini, Minor, Major and the 2,000x Grand) sit on top of the coin wins, giving the bonus a top-heavy payout structure rather than relying on a single multiplier.
• The screenshot shows the underwater setting and the extra horizontal reel, which contributes positions above the middle reels

Cons

• There are no free spins at all, the entire bonus is the Pearl Jackpot Respins, so anyone expecting a Megaways free-spins round with a building multiplier will be disappointed.
• The held-prize feature differs from a free-spin multiplier bonus; a headline maximum alone does not explain that difference
• The feature structure is close to Hypernova Megaways. Players looking for a different kind of bonus may find the change of scenery insufficient.
• Six or more scatters are needed for the feature; a near miss does not carry scatter progress into the next paid spin

How the Game Works

Atlantis Megaways has six reels and a horizontal reel above the middle four. The top reel contributes a position to each reel beneath it; a reel can have up to seven symbols including that extra position. At full height, seven positions across six reels give 117,649 ways. Matching symbols pay from the leftmost reel across adjacent reels. Winning symbols disappear and replacements arrive, allowing another win in the same paid round.

Symbols and Paytable

Underwater characters and treasures form the premium symbols, with card ranks below them. Wilds appear on the horizontal top reel and substitute for regular paying symbols, but not scatters. The treasure chest and pearl clam scatters belong to the Pearl Jackpot Respins feature. Their prize role is separate from matching ordinary symbols across the reels.

Pearl Jackpot Respins, the only bonus

Landing six or more treasure chest and pearl clam scatters in one spin sequence triggers the respins. The current number of Megaways and all the triggering scatters lock in place, every other position blanks out, and you start with three respins. Each new scatter that lands locks in and resets the counter back to three, so the round only ends when you run out of respins or the screen fills completely. Treasure chests are marked with a random coin win from 1x to 100x your bet; pearl clams award one of the four fixed jackpots, topping out at the 2,000x Grand. This is the closest a slot like Atlantis Megaways gets to a free-spins round, and the slowly filling grid is where all the anticipation lives.

Cascading Reactions

Every base-game win starts a Reaction. Winning symbols disappear, replacements fall from above on the main reels, and the horizontal reel refills from the right. Another winning combination continues the sequence. The ordinary symbol paytable applies here; the held-prize collection in Pearl Jackpot Respins is a separate feature. A long chain of reactions and a long respin feature therefore describe different events.

Following a Pearl Jackpot round

Once six or more scatters start the feature, those symbols stay in place. The remaining positions spin with a counter of three. A new scatter also stays, and the counter returns to three. The round finishes when the counter runs out or every visible position contains a scatter. The original Atlantis Megaways rules separate these held prizes from ordinary symbol wins, which do not pay during the respin feature.

A counter example

Suppose the feature begins with six held symbols. Two respins add nothing, leaving one respin. If the next spin adds a new scatter, there are now seven held symbols and the counter goes back to three. The counter resets to three; it does not add three on top of any remaining spins. This is an illustration of the sequence, not a recorded result or an estimate of how often a symbol will land.

Fixed prizes and displayed cash

The four named prizes are Mini at 10x, Minor at 50x, Major at 250x and Grand at 2,000x the triggering total bet. Mini and Minor can appear more than once in a feature; Major and Grand are each limited to one award. These are fixed stake multiples, not a growing progressive pot. Ordinary scatter prizes range from 1x to 100x. Wizard Slots’ game rules also explain that displayed non-jackpot scatter amounts already include the total bet.

For a £2 triggering stake, a 10x prize corresponds to £20. If the symbol is already displaying £20 as a cash amount, multiplying that displayed figure by £2 again would count the stake twice. Likewise, adding displayed cash values means adding pounds to pounds. Keep a multiplier such as 10x separate from a currency amount such as £20 when reading the board.

Why the triggering layout matters

The ordinary Megaways count can change between paid spins. Once Pearl Respins begin, the current layout is held along with the triggering scatters. The feature is therefore filling the positions that were available at entry, rather than rolling a new reel height on every respin. A 117,649 maximum describes the largest possible base layout; it does not mean that every bonus begins with forty-two spaces.

The number of held symbols and the number of empty positions answer different questions. Six starting scatters satisfy the trigger. The remaining visible spaces define where more prizes can appear. Seven held symbols on a smaller board and seven on a larger board can leave different numbers of gaps. Do not infer the chance of filling those gaps from a screenshot alone.

In an illustrative £1 feature, two 3x chests and one Mini at 10x add £6 and £10 respectively to the collection. If other symbols display cash amounts, add their displayed currency values without multiplying them by the stake again. A symbol-count total and a cash total need separate readings: another occupied space can carry a different prize from the previous one.

An empty respin reduces the remaining counter. A respin that adds several scatters still resets it to three, rather than awarding three separate batches of spins. At the end, the held scatter prizes are resolved; the ordinary symbol paytable does not run as a second layer of line or ways awards during that feature. Atlantic Lottery’s original game help describes the locked layout and fixed-prize structure.

Bonanza is a useful contrast within Megaways. It also replaces winning symbols, but its GOLD trigger leads to free spins with a continuing multiplier. Atlantis instead moves from ordinary reactions into a held-prize collection. A long reaction sequence is not the same event as repeatedly resetting a respin counter, even if both begin from variable-height reels.

For the closest visual and structural comparison, begin with Hypernova Megaways. For a familiar pearl round on fixed dimensions, use Atlantis 10K Ways. For a conventional fantasy reel game, the wider alternatives below change the matching rules as well as the setting. This gives the shortlist three different purposes instead of treating all fantasy artwork as the same experience.

Similar Slots Worth Trying

The following fantasy titles widen the artwork selection. They are less direct matches than Hypernova’s reactions and held-prize feature or Atlantis 10K Ways’ pearl round. Compare the win format and bonus purpose before choosing by the mythical setting.

King Maker is another Big Time Gaming variable-ways game with a free-spin feature. That makes it a contrast to Atlantis’s held-prize respins: its reel wins remain part of a free-spin sequence rather than turning every scatter into a locked prize position. The medieval artwork is secondary to this difference. A shared Megaways label establishes a way of arranging symbols, but does not establish identical bonus rules or payout probabilities.

Aurora Wilds uses a five-by-three display with ten fixed lines. This makes it a more compact conventional reel contrast to Atlantis’s changing heights and horizontal top reel. Its mystical artwork offers a visual connection, but it should not be called a calmer or lower-loss version of Pearl Respins. A volatility label cannot predict the length or cost of an individual session. Read its own feature rules when comparing the wild behaviour.

Avalon 2 uses 243 ways and an Arthurian setting, with its Grail feature organised around different free-spin modes. That changes both the layout and what the bonus asks you to follow. Atlantis holds scattered prize symbols with three resetting respins; Avalon’s mode-based free games continue to resolve reel combinations. More modes mean more rules to compare, rather than proof of a richer payout or a better return from one visit.

5 Knights supplies a medieval alternative with twenty-five fixed lines and multiplier free spins. The multiplier affects qualifying reel wins; a held chest in Atlantis instead contributes its displayed prize to the collection. These are different ways of building a feature total. Use 5 Knights for the setting and fixed-line contrast, while Hypernova remains the closer choice for the held-symbol sequence. None of the themed suggestions duplicates a rule merely by sharing fantasy characters.

What the Critics Say

Online-Slot.co.uk: The Atlantis Megaways slot is identical in terms of gameplay to ReelPlay’s other Megaways slot, Hypernova Megaways. The only difference is the theme which is much better as this game is better to look at.

TheSlotBuzz.com: An epic Megaways™ slot from ReelPlay based on the myth of Atlantis, with stunning production values and a classic version of the famous expanding reels format with new re-spins and Pearl Jackpots features added.

JohnSlots.com: Discover wonders of the unknown utopian civilization said to be living on underwater islands rich in rare treasures and jackpot payouts. Experience rewarding jackpot respins, consecutive winning reactions and prizes from the depths of the sea worth 8,641x your stake.

SlotsWise.com’s quoted review attributes Atlantis Megaways to Yggdrasil. The game identified on this page is ReelPlay’s Atlantis Megaways, listed by Relax Gaming. Use that named release and its original help for the pearl feature; the review’s attribution should not be used to identify the supplier.

SlotsTemple.com: Atlantis Megaways is a ReelPlay online slot that features a vibrant look. The game is set underwater with some beautiful sea creatures as symbols. They are designed with a lush colour scheme that is sure to dazzle you. Overall, it’s quite a beautiful game that draws you in as soon as it loads.

The underwater art and the absence of a conventional free-spins round are useful points to consider in these reviews. Claims that two games have identical mathematics require more than a visual resemblance, however. Atlantis is easiest to assess by its own rules: reactive wins in the base game, then held prizes in Pearl Jackpot Respins. The respin counter, the prize values and the conditions that end the feature matter more than calling it a reskin.

Atlantis and Hypernova: what the comparison establishes

Relax Gaming’s listing links Atlantis Megaways to Hypernova and describes the reactive-win format and variable ways. That supports comparing their feature structure. It does not supply a side-by-side mathematical specification proving identical RTP configurations, outcome probabilities or win limits.

Use Hypernova Megaways as a starting point for the shared design, then check each game’s own information screen. The third-party comments above express stronger views about equivalence; those opinions do not establish identical payout settings. Relax Gaming’s Atlantis Megaways listing describes it as a follow-up to Hypernova using the same broad formula.

Hypernova and Atlantis 10K Ways compared

Hypernova Megaways: the closest feature structure

Relax Gaming’s Hypernova listing describes variable ways up to 117,649, reactive wins and a jackpot feature with up to 42 prizes. Those are the useful similarities with Atlantis. Hypernova uses a space setting, whereas the screenshot below shows Atlantis’s sea creatures, royal symbols and underwater ruins. The comparison is about a base-game reaction sequence followed by prize collection, rather than merely two games sharing the Megaways name.

Compare the in-game information screens separately before using a return percentage or prize limit from one title for the other. A shared feature outline does not tell you the probability of triggering it, the distribution of its prizes or the configuration loaded by a particular casino. Hypernova belongs near the top of the shortlist for structural similarity, while the lost-city titles further down are grouped by theme.

Atlantis 10K Ways: fixed dimensions, familiar respins

Atlantic Lottery’s Atlantis 10K Ways rules specify four positions on the outer reels and five on the middle four, including the top reel. Multiplying 4 × 5 × 5 × 5 × 5 × 4 gives 10,000 ways. That fixed structure is the main difference from the original’s changing heights. Six scatters still start three Bonus Respins, with new scatters held and the counter reset. The familiar pearl feature therefore survives the change in grid.

Configuration also matters within the newer title. Atlantic Lottery lists 96.16% RTP, while Grosvenor’s Atlantis 10K Ways page lists 94.38%. Neither percentage should be copied into the original Atlantis Megaways information. Check the exact game name and its own rules first. A matching underwater background does not establish the edition or the RTP version.

More Lost-City Games

Strip away the underwater art and this is a Megaways game first and an Atlantis game second, but the lost-city setting is the reason most players pick it over its space-themed twin. If the sunken city is what you are after, there are plenty of games similar to Atlantis Megaways below.

Our favourite Atlantis slots

Atlantis is one of the most reused themes in slots, so there is no shortage of games like Atlantis Megaways if it is the sunken-city setting you are after rather than the Megaways engine specifically.

The underwater setting distinguishes Atlantis from Hypernova. Their related design makes them useful comparisons, but confirm each version’s RTP and feature rules rather than assuming the mathematical settings are identical.

If you simply want more of the lost-city theme, similar slots to Atlantis Megaways include Atlantis Thunder, Atlantis Queen, Atlantis Power Combo and the original Atlantis, each takes the same mythical setting in a different direction.

Other Atlantis-themed demos worth a spin include Atlantis Slot, Atlantis Queen and Atlantis Thunder.

More From ReelPlay

ReelPlay is an Australian games studio (formerly Chance Interactive) best known for inventing the Infinity Reels mechanic and for building the Hypernova/Megaways engine that powers this slot. Atlantis Megaways is listed by Relax Gaming, which identifies ReelPlay as the studio and describes its relationship to Hypernova Megaways.

ReelPlay’s relationship with Relax Gaming covers both distribution and later development work. In its September 2024 partnership announcement, Relax described more than five years of collaboration and over 70 ReelPlay releases, with ReelPlay becoming a Silver Bullet partner. A platform relationship is distinct from the name of the studio that develops a game.

Other ReelPlay games include Hypernova Megaways, Odin Infinity Reels Megaways, El Dorado Infinity Reels and Gems Infinity Reels. Hypernova is the direct comparison for Atlantis’s reactive wins and held-prize feature. The Infinity Reels titles belong to a different format built around reel expansion. Atlantis 10K Ways returns to the underwater setting with a fixed 10,000-way layout and Bonus Respins. The bonus collects held symbols through resetting respins; it does not add a conventional free-spins round.

ReelPlay’s Infinity Reels games provide a separate layout comparison. Their central idea is adding reels as the game develops, rather than holding the visible Atlantis board for prize respins. Odin Infinity Reels Megaways and El Dorado Infinity Reels should therefore be assessed through their expanding display rules. The studio name is a family connection, but it does not turn every ReelPlay title into another Pearl Jackpot game.

If you are chasing a specific mechanic rather than the theme, these picks share Atlantis Megaways’ headline features, the 117,649-way Megaways grid, the fixed jackpots, and the locking no-win respins.

Other Slots With Big Dynamic Ways-to-Win

Bar X Safecracker Megaways (Blueprint Gaming’s fruit-machine take on the mechanic) and Dragon Born (Big Time Gaming’s original 117,649-way engine showcase from 2016) are the closest true matches for the exact ways-count. Wild Weather (Tom Horn Gaming, 18 fixed paylines) and Pillars Of Asgard (Scientific Games, scaling all the way up to 1,000,000 ways) sit in the wider dynamic-reel and big-ways family rather than sharing the identical 117,649 ceiling, but all four add the free-spins round this game leaves out.

Progressive games as a separate comparison

For a true progressive prize rather than fixed jackpots, Coin Coin Coin and Arabian Nights both pool a network jackpot that can dwarf this slot’s 2,000x Grand.

Games with No Win Respins

For more of the lock-and-respin feeling that drives the Pearl Jackpot round, Megajackpots Wheel Of Fortune On Air and Jackaroo Jack both build their bonus around held symbols and repeated respins.

Frequently Asked Questions

What RTP does this slot run at?

Atlantic Lottery’s published original Atlantis Megaways help lists 96.095% RTP, commonly rounded to 96.10%. That is the documented configuration, not a universal return for every operator. RTP is a long-run mathematical percentage and does not forecast a respin prize or a session result.

Does it have a free-spins round?

No. Unusually for a Megaways slot, there is no free-spins round at all. The single bonus is the Pearl Jackpot Respins, triggered by six or more chest and clam scatters in one spin sequence.

What is the maximum win?

The historical catalogue lists 8,641x stake, but the game-help document linked above does not establish that figure as an overall contractual cap. It does document the Grand at 2,000x the total triggering bet. Use the loaded version’s overall payout limit; a fixed Grand award and the total feature maximum are different figures.

How do the Pearl Jackpot Respins work?

Land six or more chest and clam scatters and the triggering scatters lock in for three respins. Each new scatter resets the counter to three. Chests pay 1x to 100x your bet and clams award one of four fixed jackpots, up to the 2,000x Grand.

Is it the same game as Hypernova Megaways?

Relax Gaming describes Atlantis as a follow-up to Hypernova Megaways. The games have related features, but the product listing does not establish that every mathematical setting is identical. Check the information screen for each version.

What are some slots like Atlantis Megaways?

Hypernova Megaways is the closest comparison for reactions followed by held-prize respins. Atlantis 10K Ways keeps the pearl feature on a fixed layout. King Maker and Bar X Safecracker Megaways offer broader Megaways routes; Atlantis Thunder, Atlantis Queen and the original Atlantis broaden the setting. Compare each bonus separately.

Who developed this slot?

It was developed by ReelPlay and is listed in Relax Gaming’s catalogue. Please gamble responsibly; this game is for players aged 18 and over.

Our Verdict on Atlantis Megaways

Atlantis Megaways suits a comparison based on held prizes and an underwater setting. Its Pearl Jackpot Respins keep the collected scatters visible while the remaining positions spin, making the prize collection distinct from the base game’s cascading wins. Hypernova Megaways is the closest starting point for that combination of features. Atlantis 10K Ways is the more useful comparison if you want to keep the setting while changing from variable reel heights to a fixed layout. Neither comparison needs an assumption that every payout setting is identical. The main limitation is clear: players wanting a conventional free-spins round with an increasing win multiplier will need a different feature structure. The fantasy and Megaways alternatives above broaden the choice, but their individual bonus rules matter more than a shared setting or a larger advertised win figure.
