About
Created by indie developer Gaz Thomas (that's me!) in November 2008 Super Stacker was one of the first examples of a physics puzzle game. At the time Gaz was creating a series of short experimental game ideas for his website The Game Homepage and this was one of them. Super Stacker was an instant viral success quickly spreading around the internet and enjoyed by millions of players. Super Stacker 2 was Gaz's follow up which expanded and improved on the idea. Released February 2009 Super Stacker 2's exploded in popularity immediately on release. It went on to be played hundreds of millions of times and was one of the most popular flash games of the era. The version of the game on this page is the current definitive version. It has been adapted and improved as of May 2026 to work in modern browsers. This includes full mobile support so you can now play it on mobile as well as PC. In addition the level sharing system has been repaired and updated and even a discord server created to share levels with others. Whether you are here for nostalgia or a brand new player have fun and thanks for being a Super Stacker!
