Pokemon Trozei!

"A meager selection of gameplay modes keeps Trozei from being essential, but the core gameplay remains engaging, regardless."

"Pokemon Trozei is a new take on the familiar tile-sliding puzzle design, and it's a really good one. It's not the usual fare, and its heavy focus on combos may be a bit misleading that there's not a whole lot of challenge. It's actually quite tough, and in some cases, addictive to try and grab the high score quotas and random, rare Pokemon critters that wander onto the playfield. It's not a classic in the same way that Tetris and Puyo Pop have become in the genre, but it's still a lot of fun and definitely a unique diversion for DS owners."
