Cosmo Gang the Puzzle is a 1992 falling block puzzle arcade video game developed and published by Namco worldwide. The third game in its Cosmo Gang series, succeeding that year's Cosmo Gang the Video, players stack groups of blocks and aliens known as Jammers in a vertical-oriented well. The objective is to clear as many objects on the screen before they reach the top of the screen. Blocks are cleared by aligning them into complete horizontal rows, while Jammers are cleared by defeating them with blue-colored spheres.
