Calm Games Hub

Calm Sort is a color-sorting puzzle with everything that makes the genre great and none of what ruined it. No ads. No tracking. No energy timers. Pay once, play forever.

Pour colored layers between glass vessels until every vessel holds a single color. Simple to learn, genuinely deep to master.

Optional Game Center features — leaderboards and friend matches — are provided by Apple and require Game Center and an internet connection. Airussolutions does not operate an account server and does not receive your Game Center friend list, profile, or match data; GameKit handles these features on your device.

Made by a small independent studio. When you pay once, you are the customer, not the product.
