Where to play Big Atlantis Frenzy — 96.77% RTP, free demo and specs

Inside the game

Captured in the studio's own free demo on 11 September 2026. Nothing below is taken from a press release or another site — it is what the game shows when you open it.

The base game — Big Atlantis Frenzy — The base gameFive reels, five rows: the grid is set to its largest size, the one that puts 20 lines in play, and the double arrow at the top right shrinks it. The pot of gold, the game's highest-paying symbol, has landed three times on this opening screen. On the left the game's two buttons sit waiting: Buy Bonus, and Chance ×3 with its switch still at rest.

Game rules, page 1 — Big Atlantis Frenzy — Game rules, page 1The Wild, shown in its four guises — the fisherman in his rubber ring changes colour, not function. It appears only during Free Spins, can land on any reel and replaces everything except Bonus and Fish symbols. At the displayed 0.30 FUN bet it pays 0.30 FUN for 2 symbols, 0.75 FUN for 3, 3.00 FUN for 4 and 30.00 FUN for 5.

Game rules, page 2 — Big Atlantis Frenzy — Game rules, page 2The Bonus symbol is a fishing boat, and it can land on any reel in the main game: three or more open the Free Spins, with their number depending on how many boats landed. The game specifies that a winning combination landing on the same spin is paid out before the bonus round starts. The next section opens on the Fish Symbols.

Game rules, page 3 — Big Atlantis Frenzy — Game rules, page 3The four fish and their scale, where colour sets the value: red is worth ×20 of the total bet, orange ×15, blue ×10 or ×5, green ×3 or ×2. In the main game, two or more fish on the same payline add their amounts together. During Free Spins they land only on reels 2 to 5 and pay only when a Wild is present — the Wild collects and pays out the sum of every fish on screen.

Game rules, page 4 — Big Atlantis Frenzy — Game rules, page 4The paytable at a 0.30 FUN bet. Two symbols already pay from two of a kind: the pot, up to 30.00 FUN for five, and the gem, up to 7.50 FUN. The others need three — the seahorse climbs to 4.50 FUN, the rubber ring to 3.00 FUN, while the amphora and the A and K letters all top out at 1.50 FUN.

Game rules, page 5 — Big Atlantis Frenzy — Game rules, page 5The end of the paytable — Q and J share the lowest scale, 0.15 / 0.45 / 1.50 FUN — followed by the game's first feature, Reel size. The illustration stacks the three available formats, 5X5, 4X5 and 3X5, and shows the double arrow used to switch between them.

Game rules, page 6 — Big Atlantis Frenzy — Game rules, page 6The opening page: the game calls itself a slot inspired by the sunken island of Atlantis and lists its levers — the reel size left to the player, the Bonus and Wild symbols, the Free Spins, the fish carrying a cash amount, and Buy Chance, which raises the odds of triggering the bonus. The instructions note that the number of lines follows the grid: 5, 10 or 20.

Game rules, page 7 — Big Atlantis Frenzy — Game rules, page 7After the Autospins stop conditions comes the Features block. Reel size sets the rule of the game: 5x3 gives 5 paylines, 5x4 gives 10, 5x5 gives 20, and the arrow at the top of the screen does the switching. The Free Spins paragraph then gives the full scale — 3 Bonus symbols open 10 spins, 4 open 15, 5 open 20.

Game rules, page 8 — Big Atlantis Frenzy — Game rules, page 8The densest passage of the panel: every 4th Wild retriggers the feature for 10 extra free spins, three times at most, with a ×2 multiplier on the first retrigger, ×3 on the second and ×10 on the third — applied to the total win of every spin. The fish scale is restated, then Buy Bonus, which buys the free spins at the current number of lines or activates Buy Chance.

Game rules, page 9 — Big Atlantis Frenzy — Game rules, page 9The spin results page: wins on several active paylines are added together, only the highest win is paid on each line, and payline wins are multiplied by the bet per line — except for Bonus symbols. One detail matters: free spins are played at the same bet and the same number of lines as the round that triggered them.

Game rules, page 10 — Big Atlantis Frenzy — Game rules, page 10The game's figures page. It announces that RTP depends on the reel size, then gives the same value for all three: 96.77% on 5x3, on 5x4 and on 5x5 alike. The two buy returns follow the same line — 96.77% for Buy Bonus and 96.77% for Buy Chance, whatever the grid.
