An interesting an often overlooked spin-off, Block Ball is Kirby's take on games like Breakout and Arkanoid. Like in those games, each stage is completed by clearing all of the breakable blocks. Kirby can use one of four Copy Abilities to perform strategic tricks in order to get the highest score possible. There are ten levels--each with a boss at the end--and one secret stage that is unlocked if the player is good enough.
