The Powder Toy
Mix materials. Watch the physics unfold.
Explore a blocky procedural world, gather materials and shape a small WebGL sandbox. It runs on an external host; gameplay and terms follow that page.
Opens on: NetCraft GitHub Pages demo. New tab; host requirements apply.
This legacy MIT browser project describes a WebGL voxel sandbox with procedural terrain, blocks, plants and day/night changes. Its repository also discusses local persistence and optional multiplayer server support; those features were not checked in the linked demo. The page returned HTTP 200 on 2026-10-16, but gameplay, saves, multiplayer and device behavior were not tested.
Denny Games has not verified this external build's gameplay, browser compatibility, controls or save behavior. Check the host's current requirements.
Play style: Check host controls. This game runs on an independent host or browser build. Denny Games does not manage its account, session or saves; see the notes above for how this build handles them.
