About
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!

This game started out great, but now it's unplayable. I was having fun creating all kinds of tracks and unlocking all the different pieces, but my neighborhood had a sudden power outage. After the power came back on, I tried to launch the game, but it keeps freezing on the "Supporter Pack Installed" screen at launch. I can't click on anything except the "Don't show this again." checkbox. The animation for the "Let's go!" button plays, but clicking on it does nothing. I am stuck on this screen and can't get it to go away. There is also a "Challenge completed!" flyout in the top-right corner with <challenge description> below the title. It's as if I completed a challenge, but this shouldn't happen as soon as I open the game. I hope they fix this, because I was actually really enjoying the game, but sadly, I can't recommend it if I can't even load into the main menu.
Très bon jeu, pas cher. J'y retrouve le plaisir de créer des circuits de billes que je ne peux pas faire en réel à cause d'un problème de tremblement des mains. Le jeu à du potentiel, j'aime particulièrement les haut-parleurs qui permettent de créer une ptite musique tout en s'amusant. Le seul souhait: pouvoir enregistrer les parcours en vidéos pour les partager.

Great Core Concept, But Needs Controller Support Cozy Marbles is a delightful, relaxing physics sandbox that nailed its core premise with charming track customization and satisfying marble runs. However, the current control scheme holds it back on portable setups. As someone who primarily plays with a gamepad—frequently on handhelds like the Steam Deck or via mobile setups with a physical controller attached—having to rely on touch controls or mouse emulation takes away from the experience. If the developer adds native controller support with refined UI prompts and direct grid navigation for placing track pieces, this will easily become a staple in my portable gaming library.
Brings my Inner child back out to play. Highly recommended if you enjoy cozy creative games.
Ayant toujours été jaloux de mes anciens camarades de classe, à l’école primaire, qui possédaient ce jeu où l’on devait faire traverser une bille à travers un parcours du combattant. De très longues années plus tard, il m’a semblé naturel d’acheter ce jeu, qui m’apporte DOPAMINE et nostalgie. Hâte des nouvelles mises à jour..

Very fun and chill little game!
I love the game! It's amazing, but I'm bummed that there is no custom color option for each pattern of marbles. It would be really cool. Other than that just a few medium pieces, extra cosmetics (I would even buy a reasonably priced DLC for cat ears, and new track colors like Sakura, and of course some decorations along the tracks. And what I really miss, is just slopes and straight areas without any rails or guards to do endurance/survival challenges. I can recommend the game if you are prepared that the things you long for might not be added to the game. Still a good one to build a few fun courses and race your marbles for fun. EDIT: the dev is super open for communication also slopes and straights without any railing was ALREADY IN THE GAME, I was just not seeing it. Good game, support the dev.
Bought this to play with my son, but we both lost interest after about 10 minutes of finishing the tutorial
