How to Play Bonus Island


Before playing Bonus Island, it is vitally important that you set yourself a stake that you are comfortable to bet. This can be done by adjusting the arrows above the coin images situated to the left of the reels grid. Please remember that you can adjust your stake to suit you at any time during the game.


Once you are comfortable with your stake, begin the game by selecting the spin button on-screen. This will spin the reels and the game will begin. If you wish to use the iconic autoplay function, select the autospin button below the main spin button and choose the number of spins you would like to be spun automatically. The autoplay function in Bonus Island also comes with loss limits that will stop the game if they are reached.

Bonus Island Bonus Features

Mystery Boost

There are different mystery symbols that can appear on the reels at any point during the game. If you land a transform symbol whilst there are mystery symbols on the reels, they will be transformed into standard symbols or coins, potentially leading to winning combinations being formed.

Coin Bonus

If mystery symbols are transformed into coins, the coin bonus symbol will be triggered. Any coins that have cash rewards will spin on the reels where mystery symbols were and once they have stopped spinning, cash values will be awarded.

Bonus Island Feature

If you achieve 4 or more winning cascades, the Bonus Island feature will be triggered. 4 consecutive cascades will award the bonus, 5 consecutive cascades will award the mega bonus whereas 6 or more consecutive cascades will award the epic bonus.

Free Spins

Free Spins are awarded via the Bonus Island feature with an unlimited win multiplier increasing during every cascade whilst the Bonus Island feature is being triggered. Any winning combinations from the Free Spins bonus will be multiplied by the current multiplier at the start of the winning cascades that initially awarded the Bonus Island feature.
