"Fireboy and Watergirl" is a children's PC game series created by Oslo Albet. The series includes five online flash games distributed by Miniclip.com and Armor Games, with a sixth game in production, as of 2015. The games are free to play and are designed to be single-player and multiplayer compatible.
The goal of each "Fireboy and Watergirl" game is to move the characters through a temple while avoiding obstacles, collecting diamonds and solving puzzles along the way. The game ends when Fireboy and Watergirl escape the temple. There are five "Fireboy and Watergirl" games available, with four unique temples: Forest Temple, Light Temple, Ice Temple and Crystal Temple. Forest Temple, the original temple, is revisited in the third game of the series. Each installment features a new collection of obstacles, interactive components and challenges.
One of the most popular elements of the "Fireboy and Watergirl" series is that each of its installments functions as both a single-player of multiplayer game, such that players can complete the game alone or with a friend. The arrow keys control Fireboy, whereas the W, A, S and D keys control Watergirl. Using these controls, a single player can move both characters through the game separately, or two players can work together to reach the end of the game.
