Jelle’s Supporter Pack | Coming 10th November!
I am super excited to announce that we are partnering with Jelle’s Marble Run! On the 10th November we will be launching a DLC pack which features 32 Marbula One team marbles,…




Engineer the marble run of your dreams. No need to get it perfect – just release your marbles and let the good times roll.
Cozy Marbles is a comfy game about building marble runs. Using a huge range of bits and pieces from charming homes, fairytale realms and starlit spacecraft, fit together the marble course you’ve always wanted to build and play with. Unwind to a bespoke lo-fi soundtrack and roll with the nostalgia.

Tinker with freeform construction tools and a rich library of parts. Design awesome spirals, 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 over obstacles with boosters, ramps and cannons, floating dreamily through anti-gravity fields, and even making music with xylophone blocks.
Play in a range of environments with themed parts:
A mellow Living Room, in daylight or at night.
A whimsical Fairytale Tavern, the perfect place to build a castle coaster or labyrinthine mushroom forest.
A mesmerizing Space Station for high-tech futurism including portals and laser tunnels.

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, patterns, national flags, facial expressions, stylish hats and silly little arms that flail while rolling. Beat challenges to unlock even more customization options, track pieces and environments.

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, drop your marbles and watch them race to the end. Use checkpoints to split the track or set up multiple start and finish lines wherever you want. Make your race sweet and simple, or huge and complex with tons of laps and hundreds of marbles! May the best one win.

The next step after perfecting your marble masterpiece (or diabolical marble trap) is to share it with the world. Export and import courses to show off your build and try everyone else’s. If you’re a streamer, use Twitch integration to let Twitch Chat drop marbles into your course and join your race!
