As blocks fall from above, players must align similar designs by groups of three or more to launch them back up. Players can move blocks only vertically (preferably with the stylus, although the game can be played with the plus control pad). Each planet has its own gravitational rules and block style, so as players unlock new ones, they must learn new skills. There are many modes, and in all of them players earn Meteos – anything launched off the top of the screen goes into a bank, and players can then spend them to unlock new planets, items, features and modes.

Special powers/weapons/moves/features: There are an incredible number of modes, from Star Trip (progress from planet to planet) to wireless multiplayer to deluge mode, where the Meteos fall at a steadily increasing rate. Not only that, but almost every mode is customizable, allowing players to set the difficulty level of their opponents, time or stock limits, or even item sets. Items vary from vision-obscuring smokescreens to Meteos-destroying hammers. Besides an instantly addictive multiplayer mode, this game also features DS Download Play, allowing players to fight up to three friends with just one game card.
