Ball is played by controlling the character's arms, moving them left and right, to repeatedly catch and throw balls flying through the air like a juggler. The game ends if even one ball is dropped to the ground. There are two modes, GAME A and GAME B. GAME A has two balls, with one point awarded for each ball received, for a maximum score of 999 points. GAME B serves as a hard mode, having three balls, with 10 points awarded for each ball received, for a maximum score of 9,990 points. The ball's movement speed will frequently increase and decrease as the game progresses, in an attempt to throw the player off.
