Big Atlantis Frenzy

Big Atlantis Frenzy Slot Review — BGaming

Big Atlantis Frenzy, released by BGaming on 9 June 2022, runs on a 5×3 reel grid across 5 paylines and combines a Hold and Win respin round with a Bonus Buy entry point, capping its theoretical top payout at 4,320 times the stake.

BGaming, the studio behind Big Atlantis Frenzy, is headquartered in Valletta, Malta, and holds a Malta Gaming Authority licence (MGA/B2B/785/2020, issued 18 March 2021).

Core Gameplay Experience

Big Atlantis Frenzy builds its setting around a sunken Atlantis, populating the reels with coins, chests, fish, and a fisherman character rather than relying on a serious ancient civilization aesthetic. The theme places the title among Ancient & Historical themed slots, while the compact grid keeps the pace between rounds quick.

Features and Mechanics

Big Atlantis Frenzy builds its round structure from a set of linked mechanics rather than a single bonus trigger:

• Cash Collect / Symbol Collection — coin-style symbols land on the reels and accumulate toward the trigger for the Hold and Win round.
• Hold and Win — collected symbols hold their position while the remaining reel positions respin for extra value, the core respin mechanic of the title.
• Reel Set Modifier — the reel configuration itself can change during play, a mechanic layered on top of the base 5×3 grid.
• Stacked Wilds — wild symbols appear stacked on the reels, substituting for paying symbols across more of a payline at once.
• Scatter Symbols and Free Spins — scatters trigger the free spins round, and Extra Free Spins add further spins during the round rather than restarting it.
• Free Spins Multiplier — wilds collected during free spins raise a multiplier as the round progresses; every 4th wild applies a 2x multiplier, the 8th a 3x and the 12th a 10x, per BGaming's own description of the round.
• Bonus Bet — an optional side wager, separate from the base stake, that raises the odds of reaching the feature round naturally.
• Bonus Buy — a direct purchase into the Hold and Win round instead of waiting for a natural trigger.
• RTP Range — the game is built with more than one configured payout rate; which one runs live is set by the operator and shown in that casino's own game information.

RTP, Volatility and Payout Model

Big Atlantis Frenzy operates at medium-high volatility with a stated return to player of 96.77%.

The maximum theoretical payout at this limit reaches $4,320 on a $1 wager, a number that does not indicate the frequency of individual spin payouts.

Stakes on Big Atlantis Frenzy run from 0.1 to 100 per spin, a range wide enough to scale a session from a small testing bankroll up to a larger one.

Similar Slots — Comparison

All six games in this comparison carry a medium-high volatility rating and sit within the same ancient-treasure theme, but they differ in how far a win can run and how the feature round is reached. Big Atlantis Frenzy leads the group on return, at 96.7% against Catdiana — a noticeable gap worth about $1.40 per $100 wagered in theory — while the edge over Scale of Heaven: Anubis and Totem de Oro is smaller, about $0.63 per $100 for each, $0.66 against Raiders of the Lost Book and $0.70 against Midas Links, all still theoretical figures. On ceiling size, Midas Links tops the table at 10,000x a stake through a paylines, Hold and Win and jackpot structure, against 4,320x here; that comparison carries a mechanic caveat, since Midas Links adds a jackpot layer that Big Atlantis Frenzy does not carry, and the same caveat applies to Catdiana, built by BGaming on the same paylines-plus-Hold-and-Win core but capped at 2,500x with a jackpot rather than a Bonus Buy option. A player weighing return over ceiling size gains a small, theoretical edge by choosing Big Atlantis Frenzy over the lower-RTP alternatives in this set; a player chasing the largest single result, and comfortable with a jackpot-style trigger instead of a Bonus Buy, has more room with Midas Links.

How to Play Big Atlantis Frenzy Online

A demo mode is available for Big Atlantis Frenzy, allowing players to observe how the collection meter fills without risking real funds. The game sits alongside other titles in the Slots category and the wider slots directory for browsing similar mechanics.

BGaming’s catalogue is carried by 126 casinos as of 26 October 2026, including RoyalXO, PlanBet and KatsuBet among others; which titles and which RTP setting are live varies by operator, and the version of Big Atlantis Frenzy in play should be checked in that casino’s own game information.

Verdict on Big Atlantis Frenzy

Big Atlantis Frenzy incorporates a Reel Size Change feature (customizable grid: 5×3, 5×4, 5×5), and its 96.7% RTP at medium-high volatility keeps the payout math on the steadier side of that risk band without flattening it into a low-volatility release. It suits a player who wants Hold and Win-style respins, a defined 4,320x ceiling and occasional free-spin multipliers, and who sizes stakes for streaks without a payout; it is a weaker match for a player who wants frequent, low-swing wins at minimal volatility, or who specifically wants a jackpot layer of the kind built into some of the comparable titles above.
