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 Klaxes and five tiles compose three Klaxes. Horizontal Klaxes are worth more than uertical Klaxes, while diagonal Klaxes are worth still more. Tiles come in 10 different colors. There are three difficulty levels. Remove tiles of the same colour from the conveyer belt.
