Trioncube

is a puzzle video game developed by Namco Bandai Games and released for the Nintendo DS. It follows The Captain, sole pilot of the penguin-shaped spaceship Penko, in his pursuit of the princess captured by the evil Hell Metal and King Pluto.

==Gameplay== Trioncube consists of 45 levels and four different game modes, each of which has the player moving their ship toward an end goal by combining trominoes (a la Tetris’ tetrominoes) into overlapping 3x3 squares, referred to in-game as cubes. Creating cubes in succession starts a combo, which ends either when a certain time passes without placing a block or a block is placed that fails to form a new 3x3 cube. This moves the ship a distance forward depending on the size of the combo, completing the level if the end goal is reached before the timer runs out. Ending a combo produces coins, which can be used to unlock various in-game graphics and sound effects.
