Tinker with freeform construction tools and a rich library of parts. Design awesome loops, twists and drops, then roll your marbles off on their adventure. Take “playing with marbles” to a whole new level by guiding them across complex courses, bouncing them over obstacles with boosters and ramps, and even shooting them from cannons.

Build your marble run from wood, metal or plastic, choose its colors and give it a name. Customize your marbles with a range of colors, facial expressions, stylish hats and silly little arms that flail while rolling.

Cozy Marbles is a little game with a big brain. Plan and experiment with all sorts of marble constructs, from marble rollercoasters to wacky apparatus. Watch your marbles flow through carefully laid routes… or fly way off track!

Assemble a marble course, place its finish line, and drop your marbles to watch them race to the end. May the best marble win.

The best next step after perfecting your marble masterpiece (or grotesque marble trap) is to share it with the world. Export and import courses to show off your build and try everyone else’s.
