Big Atlantis Frenzy Slot Review

Big Atlantis Frenzy lets the player choose a five-reel height, setting paylines: 5×3 gives five, 5×4 gives ten, and 5×5 gives twenty. Fish change roles by mode. In the base game, three or more on a winning line pay displayed random amounts; during Free Spins, Fish on reels two through five need a Wild. Wild milestones award extra spins and multipliers.

Reel size sets the line count

The configurable main grid is five reels high by three, four, or five rows. Those options correspond to five, ten, or twenty paylines respectively. The source presents this as a selectable reel-size feature, so the line count is not one fixed setting across every play configuration. Three or more Bonus symbols on any reels trigger Free Spins, with the initial award tied to the Bonus count: three give ten spins, four give fifteen, and five give twenty. These are distinct threshold awards rather than a single fixed bonus length.

The game’s Fish symbols have a mode-dependent condition. In the main game, at least three Fish must be on a winning line; each pays the random amount displayed on that Fish. During Free Spins, Fish appear on reels two through five, and the rule says they pay only if a Wild drops. The listing does not specify whether Fish must also align on a winning line in that mode, so that extra condition should not be presumed. This change means a Fish’s presence alone is sufficient only under the stated base-game winning-line rule; the bonus requires the Wild event described by the source.

Wild milestones add spins after the initial round

During Free Spins, Wilds can appear on any reel and substitute for symbols other than Bonus symbols and Fish. Every fourth Wild awards ten additional spins with a ×2 multiplier, every eighth awards ten with ×3, and every twelfth awards ten with ×10. The multiplier applies to the total win of each Free Spin. The additional spins are played after the initial Free Spins end, so a milestone award creates a later block rather than immediately extending the current sequence. The rules do not say whether the Wild counter resets after each threshold or how multiple milestone multipliers interact when awards have been earned; no cumulative formula is inferred.

Buy Bonus can start Free Spins at a price adjusted to the bet, while Chance ×3 increases the chance of entering that feature. The options disable each other, so they are alternatives rather than simultaneous modifiers. Both routes lead into the same documented Bonus-count award and Wild milestone rules; the description does not state that buying guarantees a particular Bonus count or Wild sequence. Medium-high volatility is published, but it does not quantify how often those thresholds are reached.

Published settings

BGaming lists 96.77% RTP, Medium-high volatility, maximum win €250,000, and maximum multiplier ×5,000 for the standard game. The release date is June 9, 2022. Its five-reel grid has three selectable heights with corresponding line counts of five, ten, or twenty. Fish values are random, and the available rules do not provide their distribution; neither the listed maximum nor the Wild milestones explain the likelihood of a particular bonus result.

Strengths and weak points

Strengths

The three grid choices map cleanly to three line counts, and the feature rules distinguish initial Scatter awards from later Wild milestone awards.

Weaknesses

Fish value probabilities are absent, and the rules do not settle the Wild counter’s threshold handling or how multiple Free Spins multipliers affect total wins.

Our Editor’s View

Big Atlantis Frenzy offers a clear configuration choice: increasing grid height also raises the line count. Fish change roles by mode, paying random values on base-game winning lines but requiring a Wild in Free Spins. Bonus symbols set initial spins; later Wild thresholds award additional blocks with multipliers. Fish probabilities, Wild counter handling, and multiplier stacking remain unexplained. Players can follow the adjustable layout and mode-specific symbols, though mathematical comparison needs those details.
