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!

The game is nice and chill. It's exactly what it claims to be: build tracks for the marbles, launch them, and set up marble races. The system requirements are low, and the graphics and sounds are nice. There's a sort of progression system where you can earn new building parts and cosmetics. You can share your builds through the Steam Workshop, which is a perfect solution for those who don't feel like building from scratch, and for those who want to show off their grand creations. Of course, it's not without its flaws. You can only build within a designated area, and the space around the platform is just background for atmosphere. I didn't notice any bugs except for one, which I'm sure will be patched later: right after release, my Steam achievements weren't working, even though the overlay is enabled and everything works fine with other games. I think Cozy Marbles is simply a good game in its niche, and it's very much worth its price.
Object placement is way too restrictive, even when you tweak settings. It's impossible to get really weird with it, and often even basic ideas are frustrating to get to work.

this makes me so happy
面白い。面白いんだよ。でもたまにコースがみえなくなるからそこは改善してほしい。でも面白いから👍。
Fun game that I can let the kids play too. It's both fun and easy making tracks, and downloading some amazing ones others did on the steam community. I was fine with the gradual unlocking of the marble and track pieces as it got me accustomed to trying out other ideas and pieces that I probably normally wouldn't have. The only problem I had with the game was the inability to hide the names of the marbles during a race, but that has been fixed with the latest update. I recommend it if you're looking for a fun marble run builder type of game.
Did I stay up until 4:30am playing this release night? Yes Did I mean to? Uh. No. I had never even heard of it until last night.
You know you want it. Just get it! It's awesome!
I am having such a good time playing this game. I've been looking for a slower paced game for MONTHS trying to just relax for a while. This is definitely it. There is so much to do I can feel my little monkey brain working. I like the shop system because it encourages you to really dive into the game without it feeling like you HAVE to grind achievements. The game is plenty playable without the shoppable items. I'm obsessed with silly marble racing online, so getting to make my own little races is such a good time. The customizable marbles make me giggle. The only thing I can think of to mention is that the track pieces feel pretty 1-lane heavy and trying to build wider lanes is a little frustrating and the races are my favorite part! All the pieces seem to go down? Perhaps I'm missing something or I need to think more outside the box. I can't wait to spend more time on this and I'm excited to see what else they'll do! :)
I absolutely love this game, i streamed it a day after release and it was super fun racing with my viewers. For future updates id love a replay mode to see where and how the marbles are falling off my tracks and also a speed up button for faster simulations.Plus more fun stuff obvi. Overall perfect cozy game.
