Fire and Water
Work through forest temple levels where a fire hero and water hero must cooperate to solve puzzles. Fire can walk through lava, water through ice — but neither can touch the opposite element. Collect diamonds, hit levers, and open doors together. Play solo switching between characters or cooperate with a friend.

About Fire and Water
Fire and Water, also known as Fireboy and Watergirl, is a classic co-operative adventure puzzle game originally created by Oslo Albet. Players guide two elemental characters — a fire boy and a water girl — through a series of increasingly complex temples, each themed around a different element. The game has been a browser gaming staple for over a decade.
Each character has unique abilities and fatal weaknesses: Fireboy can pass through fire but is destroyed by water, while Watergirl thrives in water but is harmed by fire. Both characters must avoid the green goo entirely. Players must navigate levers, buttons, platforms, and elemental pools to guide both characters to their respective exit doors simultaneously.
The game is best enjoyed in two-player mode, with one person controlling each character, but it is fully playable solo by switching between characters. Communication and timing are crucial — many puzzles require both characters to activate switches in perfect sync. The challenge ramps up steadily, making progress feel genuinely rewarding.
