Bonus tile icons appear randomly within the levels. They should be collected!
Rabbit Bonus Icon
If a rabbit icon appears on a tile and the player collects it, the rabbit tiles symbols multiply, replacing up to 8 tiles on the layout! Why is this good? Well, if the player collects them quickly, which is easy as they all look the same, then the result of this is often a multiplier boost as the rabbit tiles are quickly paired!
Timer Bonus Icon
Sometimes a timer bonus icon appears on a tile. If the player collects it, they get time added to their level timer. More time can give more bonus points at the end of the level!
