Plumb, Carillon and Apsis are out on Google Play
Our first three puzzle games are live on Google Play today. What each one is, what they share, how they stay free, and what comes next.

Hi everyone, today is a big day for us. Plumb, Carillon and Apsis are now live on Google Play.
Three calm puzzles
- Plumb: tilt the board and every marble rolls at once. Get each one into the hole of its own colour.
- Carillon: tap a dot and its ring pops its neighbours. Every pop is a note, so every chain plays a little tune.
- Apsis: arrows rest on orbits around a sun. Tap one and it flies straight out, if nothing is in its way.
Each one has its own launch post with more about it: Plumb, Carillon and Apsis.
From an idea to the store
I started all three on 29 September. They went into closed testing on Google Play in early October, and Google approved them for everyone on 18 October. A big thank you to every tester who played the early builds and told me what felt wrong. Many of the changes since came straight from you.
What all three share
- Every level has a solution, and none is easier than the one before.
- Every chapter brings a new rule, so the game keeps changing as you go.
- Three stars for the best solve, and a hint whenever you are stuck.
- Colour themes in light and dark, and looks of its own for each game.
- Every win makes a card you can share or save.
- They play fully offline.
Free to play
All three are free. Once you have solved a few levels, a small banner sits below the board, never over it. The first 15 levels have unlimited hints, and after that you get 3 free hints a day. Every level opens by playing, and the shop is there only if you want it. The Supporter pack turns the ads off for good and makes every hint free.
What’s next
Pyxis, our fourth game, is in testing right now. It is a calm untangling puzzle, and some of its webs are real constellations. If you want to play it early, join the testers.
If you play any of the three, a rating on Google Play helps a small studio more than anything else. And if something feels off, tell me on the game’s support page or mail me at hello@chaosmos.studio.
We post puzzles from the games on YouTube, Instagram, Threads, X and r/chaosmos_studios. Come say hi.
