Getting Started With Fireboy and Watergirl on Hooda Math
The game runs directly in your browser at hoodamath.com. You control Fireboy with the arrow keys and Watergirl with WASD simultaneously. The premise is simple enough that I wasted about twenty minutes watching people argue about controls when they should have just learned to read. This is a co-op puzzle-platformer series. Fireboy can't touch water. Watergirl can't touch lava. You have to navigate rooms filled with green gas, diamond puzzles, light switches, and teleporters. Each level requires both players to solve environmental puzzles at the same time. It sounds straightforward until you hit the early gas chambers where one player has to hold a button while the other sprints through green gas protected by crystal shields. I spent hours trying to speedrun these games thinking I could just play alone. You can't. There's no AI partner. You need a second person or you need to use the keyboard for both characters, which is actually harder than it looks because your hand has to be in three places at once — left hand on arrows, right hand on WASD, switching back and forth when someone needs to collect something at a different position.
The actual mechanic that trips people up is the diamond puzzle. In certain rooms, each character can only pick up diamonds of their own color. Fireboy picks up red. Watergirl picks up blue. If Fireboy touches a blue diamond, it counts against him and the level won't complete fully. You have to coordinate who grabs what and often one player has to wait while the other collects, then they move forward together. The levels are timed but there's no penalty for taking longer. I learned this the hard way after repeatedly failing a level because I kept grabbing the wrong colored diamond out of habit. There are also elevator mechanics where one player has to stand on a pressure plate to raise a platform for the other player. This seems obvious on paper but in practice, especially with younger players or people who've never played this kind of game before, someone will just keep running ahead and leave the other person stuck on a low platform. Communication matters more than reflexes here. If you run into issues loading the game, clearing your browser cache usually fixes it. I had a student try playing on Chrome one day and the levels wouldn't load past the intro screen. Switched to Firefox and it worked immediately. Different browser versions handle the Flash-era code that some of these older Hooda Math games are built on in wildly different ways. Chrome has been slowly dropping support for older web technologies which is why newer browsers sometimes struggle with certain levels.
The game is free. No download required. Just go to the site and pick a level. I've seen people pay for mobile ports of this game that do exactly the same thing but with ads injected and worse touch controls. Don't do that. The browser version is the one everyone should be using unless they need offline play, in which case the official mobile apps are the better route if you're going that direction at all.
