Play Chu Chu Rocket! (J)(Capital) Online

Chu Chu Rocket! came out on the Game Boy Advance in 2001, developed by Sonic Team. It was one of those early puzzle games for the system that felt perfectly suited for quick sessions, a clever little title that stood out without needing a lot of flash.

You don't control a character; instead, you place directional arrows on a grid to guide a stream of mice, called ChuChus, into rockets while avoiding cats. The main objective is to get a required number of mice to safety before the cats eat too many. Key mechanics include plotting paths under time pressure and sometimes scrambling to correct your mistakes as the screen fills up. The pacing starts simple but the difficulty spikes fast, demanding quick thinking and precise placement. It feels like conducting a frantic, tiny rescue operation with every level.
