The Powder Toy

The Powder Toy is now on Android! This time it is officially supported, completely free, and slightly optimized for touchscreen devices instead of the traditional mouse and keyboard Powder Toy is usually run with.

The Powder Toy is a free physics sandbox game, which simulates air pressure and velocity, heat, gravity and a countless number of interactions between different substances! The game provides you with various building materials, liquids, gases and electronic components which can be used to construct complex machines, guns, bombs, realistic terrains and almost anything else. You can then destroy them and watch cool explosions, add intricate wirings, play with little stickmen or operate your machine. You can browse and play thousands of different saves made by the community or upload your own - we welcome your creations!

The game is very resource intensive. A powerful phone is recommended to play it properly. Button sizes have been increased in many places, but you might need a large phone screen or a tablet in order to have a better experience. If you find a feature that is hard to use on a touchscreen, or is absent from the Android version of the game, leave some feedback by clicking the bug icon in game or making a post on the forums.

It is fully compatible with the PC version of the game, saves made in one version can be loaded in the other.
