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. The game features four modes: • Story mode is 45 levels and features cutscenes as well as gold, silver, and bronze completion times for each level. • Arcade is a continuous level that progressively increases in difficulty. • Endless is a game mode with 99 levels. • VS allows players to compete against a computer or one another via DS Download Play.

Trioncube was developed by Namco Bandai Games. The game was chiefly designed by Kouji Asuna and was produced by Hideo Yoshizawa, known for his work on the Mr. Driller series of puzzle games. The idea for the game came to Asuna while he was at home, watching television after a bath. He had been working on a separate puzzle game at the time and was stuck on how to bring the project together. "Something just clicked in my head as soon as this certain shape appeared on the screen," he explained. "That was the moment Trioncube started to [materialize] in my head." Asuna wanted to make Trioncube unique by emphasizing large combos rather than clearing lines. Asuna considered utilizing the DS touchscreen for moving blocks, but chose not to because "it didn't really feel natural or make things easier". The game's "cute" aesthetic was also intentional, evolving from a more basic interface to one the design team hoped would appeal to both younger and female players. Prior to its release, an Adobe Flash demo version of the game could be played on both the English and Japanese Bandai Namco websites. The Japanese site also hosted special promotional content for the game, including commercials, wallpapers, and an official manga featuring the game's development team.
