Triball is a variant of Tetris, but with balls. The game is a 3 match game. Two players play against each other.
Each player has his/her own playing field, in which he/she must rotate balls which fall from the top of the screen to form vertical, horizontal or diagonal rows of three or more. Achieve this and the balls will disappear. The aim of the game is to remove as many balls as possible from the game and score points along the way.
