Bubble Craze is a slot that does not have the standard reels layout typically associated with slots but instead has symbols represented by different coloured bubbles aligned in rows of 3, 4, 5, 4, and 3 symbols. The symbols also do not spin but pop after each turn to be replaced by more bubble symbols that rise from the bottom of the screen to form the next set of combinations.
The aim of Bubble Craze is to hit winning combinations with the different coloured bubbles. Players can earn at least 10x their stake by hitting combinations of four or more symbols of the same colour.
This slot also includes a number of special symbols that can have an influence on the game. First there are the multiplier bubbles. These symbols are bubbles that have a multiplier value up to 5x positioned at their centre. If a player triggers a winning combination of four or more bubbles including that multiplier bubble then the player will see that multiplier value added to their winnings.
Secondly, there are the free spins bubbles. These are bubbles that have a multi-coloured centre. If players manage to hit three or more of these across the reels then they will win 5 free spins.
Finally, there are the transform symbols. These symbols are bubbles that have four arrows located at their centre. These symbols will then turn all bubbles directly attached to them into the same colour to create potentially huge winning combinations. It is possible to trigger up to 10,000x the player’s stake if enough bubbles are turned the same colour.
