Cubicolor

Cubicolor is a tile-shifting puzzle game for the Atari 2600, designed by Rob Fulop and published by Imagic. Players move tiles one space at a time on a 5x5 square, attempting to recreate a pattern shown on a smaller 3x3 square using the center nine tiles.

The game includes two large playfields for competitive two-player play. Cubicolor is also noted for its extreme rarity: reportedly, only 50 numbered cartridges were produced.
