The character is located at the bottom of an infinitely high tower. His/her goal is climbing upwards and exploring the tower, trying to jump as high as possible, with good precision. The paddles are one-directional platforms, so moving upwards over them is possible. As the game progresses, faster climbing is required. Bonus score is received after continuous jumping over more than one paddle at once. Falling beyond the bottom of the screen is fatal for the character. Player can jump manually, but also this game can be easily played with only two buttons, because automatic jumping is performed right before reaching the paddle's edge.
