Three layouts beneath the surface

BGaming released Big Atlantis Frenzy on June 9, 2022. The current official profile lists 96.77% theoretical RTP, medium-high volatility and a 5,000x maximum win. These are the present profile's figures. An older publisher introduction image advertises 4,248x instead, so that startup image is excluded from the article and the older number is not treated as the current headline specification.

The layout can be five reels by three, four or five rows. Those options correspond to five, ten and twenty paylines respectively. The player chooses the size in the main game. This makes reel height a functional setting rather than a purely visual zoom control.

A taller window gives more positions to inspect, but it does not mean the same wager has automatically become better value. Check the final stake and active help after changing the setting. The linked rules define separate RTP fields for layouts, bonus purchase and Chance mode, yet leave their numerical values as runtime parameters. The 96.77% headline is not confirmation of one identical percentage across every combination.

The sea theme is readable: the ordinary game is bright, the bonus has a deeper underwater background, and the Wild counter is shown above the reels. The contrast helps distinguish the two stages even when similar symbols are present.

Fish, Bonus symbols and a published discrepancy

Three, four or five Bonus symbols trigger ten, fifteen or twenty initial free spins. These awards are agreed by the current profile and linked rules. A Bonus trigger and any ordinary line payout should be read as separate parts of the spin result.

Fish carry displayed monetary values, but their base-game trigger threshold differs between official documents. The current profile says three or more Fish on a winning line pay their values; linked rules version 1.0 dated May 19, 2022 says two or more. This review retains that difference. It does not promise that a pair of Fish must pay in every loaded version.

During free spins, Fish appear on reels two through five and require a Wild to collect their values. The rules explain that each Wild on the screen collects the sum of Fish amounts. The Wild can also substitute in ordinary combinations, but it does not replace Bonus or Fish symbols.

That distinction is central to reading the bonus. Several valuable Fish without a collector are not equivalent to an already credited collection. Conversely, the Wild's ordinary substitution role and its Fish-collection role can both matter in the same spin.

Wild milestones, paid access and our verdict

The round counts Wilds toward milestones. The fourth collected Wild awards ten additional spins with a 2x multiplier; the eighth awards ten with 3x; the twelfth awards ten with 10x. The multiplier applies to the total win of the relevant free spin. These extra stages are played after the preceding stage rather than being a guarantee that every initial spin already receives the highest multiplier.

The linked rules allow three such retriggers. Watching the milestone bar is therefore more informative than assuming that one collector immediately upgrades the entire round. A bonus can finish without reaching all the steps, and the presence of a 10x marker on the interface is not a promise of reaching it.

Buy Bonus can purchase access to free spins, and Chance x3 is a separate paid option. The current profile says the two are mutually disabled when the other is active. Neither option's universal price is inferred from demonstration screenshots. Use the amount shown in the loaded game and include that full cost when setting a session limit.

Big Atlantis Frenzy is most interesting for its configurable field and staged collector progression. Its weaknesses are the extra reading required and the documented differences in older materials. It suits someone who enjoys tracking a bonus across several phases, provided the chosen version's Fish threshold, stake and RTP are checked before play.

Evidence comes from BGaming's current profile, linked game rules version 1.0 and official publisher media. This is a rules-based editorial assessment, not a claim of a measured real-money test.
