Engineer the marble run of your dreams. No need to get it perfect – just release your marbles and let the good times roll. Watch the latest Cozy Marbles trailer for this upcoming simulator game. In Cozy Marbles, 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. Cozy Marbles will be available on PC (Steam) in 2026, and a playtest is available now on Steam.
