About Fireboy and Watergirl 3

Fireboy and Watergirl 3 is from the Fireboy and Watergirl series, the definitive two-player co-op puzzle games: Fireboy is immune to lava but dies in water, Watergirl the reverse, and every temple level needs both moving in coordination — one on WASD, one on arrows, ideally two people, one keyboard, zero arguments (good luck).

Grab your keyboard and mouse and you're set; there's no settings maze to fight through first. The game is mobile-friendly: same game, touch controls, any device. Hit the fullscreen button and the browser gets out of the way entirely. Scores here are personal: the only leaderboard that matters is your last attempt.

Tips for Fireboy and Watergirl 3

Move one character at a time through hazard sections; simultaneous panic kills co-ops.
Plan the level's mirror logic first: what she unlocks for him, what he holds for her.
Green goo kills both characters. It's the only shared enemy — respect it.
