Intelligent Qube

Intelligent Qube (アイキュー, Aikyū?) is a puzzle game for the PlayStation. It is known as Kurushi in Europe and Australia. In the game, the player controls a character who must run around a platform made of cubes, clearing certain cubes as they approach. Cubes are "cleared" by marking a spot on the stage, waiting for the cube to roll on top of it, and then deactivating the marked spot.

Intelligent Qube was well received by critics. The game performed well commercially in Japan and even won Excellence Award for Interactive Art at the 1997 Japan Media Arts Festival. A few sequels have been developed and the game has since been re-released on mobile phones and the Japanese and European versions of the PlayStation Store.
