Cozy Marbles

Cozy Marbles is a marble-run building game. You use freeform construction tools and a library of parts to design courses, then release marbles to roll through them. Build simple tracks or complex routes, and watch marbles follow the path—or fly off track.

Build a marble run

Create spirals, twists and drops, and guide marbles over obstacles with boosters, ramps and cannons. Anti-gravity fields let them float, while xylophone blocks turn their runs into music. Build with wood, metal or plastic, choose colors for your course and give it a name.

You can add checkpoints to split a track, or place multiple start and finish lines. Set up races with tons of laps and hundreds of marbles, or keep your course short and simple. Challenges unlock more customization options, track pieces and environments.

Themed environments

Build with themed parts in three settings:

• Living Room: a mellow setting available in daylight or at night.
• Fairytale Tavern: build a castle coaster or a labyrinthine mushroom forest.
• Space Station: create high-tech courses with portals and laser tunnels.

Customize and share

Customize marbles with colors, patterns, national flags, facial expressions, hats and little arms that flail as they roll. You can export and import courses to share your builds and try courses made by others. Twitch integration lets Twitch Chat drop marbles into your course and join the race.

The game includes a bespoke lo-fi soundtrack.
