As you might expect in the first GBA game from Sega's Sonic Team, ChuChu Rocket! blends high-speed action with truly baffling puzzles. The result is an addictive head-scratcher for as many as four players.

A gang of KapuKapu space cats has overrun a space port. Your job is to guide the ChuChu mice to escape rockets before the KapuKapus can have them for dinner. You'll also have to make sure the ChuChus don't fall-fall through holes in the space port floor and the KapuKapus don't beat them to a rocket.

Both ChuChus and the slower KapuKapus follow straight lines they come across an Arrow Panel that's been cleverly placed by you, at which point they head off in the direction indicated by the arrow.

Single-player ChuChu Rocket! teems with hundreds of puzzle situations. After trying your hand at the dozens of preset puzzles, you can create puzzles that you can then send to a friend's Game Pak via the Game Boy Advance Game Link Cable. A rudimentary drawing tool even allows you to create your own creatures to replace ChuChus and KapuKapus.

The multiplayer modes require only one Game Pak, although each player will need a GBA. GBA Game Link Cables will be needed to link all the systems to together. You can play a multiplayer free-for-all or opt for two-player teams.

Based on the Dreamcast hit, Chu Chu Rocket! is a first-rate hand-held puzzler for the GBA.
