A player can use power-ups to have a better shot at beating a level, such as a beach ball that allows birds to travel farther with each bounce. Power-ups can be collected by either buying them with gems or winning them by opening wooden chests. Up to 3 chests can be opened after beating a level, depending on how many stars were earned on that level (although more chests can also be purchased with gems), and on occasion, an additional chest can be opened after a certain amount of coins are collected.
