Arranging tiles dropping off a perpetually running conveyor belt is the deviously simple premise of Klax. A Klax is three or more identically colored tiles in a row. You catch and hold as many as five at a time with your paddle, then drop them onto one of file piles below. Three tiles make up one Klax, four tiles make up two Klaxs and five tiles compose three Klaxes. Horizontal Klaxes are worth more than vertical Klaxes, while diagonal Klaxes are worth still more. Tiles come in 10 different colors and three difficulty levels.
