Learn More about GameMaker

GameMaker Studio 2 is the latest and greatest incarnation of GameMaker.

Making games development accessible to everyone means taking away the barriers to getting started. GameMaker has everything you need to take your idea from concept to finished game.

Using the intuitive 'Drag and Drop' development environment you can have your game up and running in a matter of minutes without ever having to write any code! GameMaker's built-in language (GML) helps you learn to program as you go and not jump in at the deep end of coding.

It's perfect for game jams. Try for free today!
