Marble World

Marble World is a physics sandbox where you build marble runs, races, loops and machines from tracks, tools and decorations. You can simulate more than 10,000 marbles at once, depending on your computer, and create contraptions in a range of themes.

Build your contraptions

Track pieces come in different forms, sizes and themes. You can move, snap, rotate and scale them, then paint tracks and objects with customizable colours. Place decorations around your build or on the track to create interactions with the marbles. Special objects include boosters, gravity pads and spinners, and logic lets you change tracks dynamically while marbles are rolling.

Control the simulation

You can build while the marbles are moving or stop time to set up more elaborate mechanisms. Slow motion and sped-up gameplay let you adjust the pace, while the game’s physics simulation governs how the marbles move.

Marbles and races

Customize marbles with skins, names and special effects, host marble races, and share your creations with others. The game also includes Twitch integration that lets viewers join.
