Play Zooo Online

Zooo is one of those Game Boy Advance games that sneaks up on you—it looks cute with its chunky animal tiles and bright colors, but five minutes in, you're sweating. The basic idea is simple: match three or more of the same animal to clear them, like a zoo-themed Puyo Puyo. But then that little chameleon jerk starts hurling extra tiles at you, and suddenly you're scrambling to keep the screen from filling up.

The music bops along like it's not aware of the panic you're in, which just makes the whole thing funnier. I lost my first few rounds embarrassingly fast, but once you get the hang of chaining combos, it clicks—until the game decides to ramp up the speed again. It's got that "just one more try" pull, especially when you're so close to beating your high score.

If you like puzzle games that don't take themselves too seriously but still kick your butt, this one's a blast. Just don't blame me when you start seeing animal tiles in your dreams.
