Trouballs is a 2001 Game Boy Color game developed by Paragon Five and published by Capcom Entertainment, and is a puzzle game similar in design to Tetris and Puyo Puyo.

Trouballs requires players to match balls of the same color into boxes of four or six, which then disappear. Players manipulate the balls on the screen through turning wheels. Additional features include falling balls, moving winches and gears. The game has two modes: a "set number" mode that has a set number of balls on the screen, that requires the player to arrange the balls in rectangles of four or six balls until they vanish, or "ever more balls", in which balls keep falling into play, and keep the play screen from filling up with balls until the time limit.
