How the Game Runs

The base game starts when users place bets from £0.20 to £100 per spin. Each spin shows fifteen icons across the screen in three rows and five columns. Winning combinations form from left to right on active paylines. The tuna wild replaces all regular icons except the scatter boat. When three or more boat scatters land anywhere on screen, the free spins round begins. Players get eight free spins to start with chances to win more during the feature. During free spins, every wild tuna that appears adds a 1x multiplier to the total. These multipliers stack and stay active until the round ends. Landing more scatter boats adds four extra spins to the counter.

Special Features and RTP

The return to player sits at 96.12% with medium to high volatility. Maximum wins reach 10,000 times the bet amount through combined features and multipliers. The fishing boat bonus triggers randomly during any base game spin. This mini-game shows different fishing spots on screen where players pick locations to reveal instant prizes. The round continues until finding the ’collect’ message. Key bonus elements include:

1. Random wilds that add two to five tuna symbols on any spin
2. Mystery icons that all change into the same paying character
3. Cascading wins where winning icons disappear and new ones fall down
4. Buy bonus option for instant access to free spins at 100x the stake
