Trioncube

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:

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.

The game received "mixed" reviews according to the review aggregation website Metacritic. It was said to be far too easy, with the slow pace of the game giving a lack of challenge and making it dull. ONM mentioned that the game was not as addictive as Tetris, and there were better puzzle games on the DS. In Japan, Famitsu gave it a score of 25 out of 40.

GamePro said, "In the end, Trioncube doesn't offer much for a puzzle game. There's little depth or difficulty to be found, and while the odd story is surprisingly entertaining, it isn't enough to keep you playing for long."
