Thanks for playing SolaMoon! If you have a question, a bug to report or a suggestion, we would love to hear from you. Most emails are answered within a few business days.
When reporting a problem, it helps to include:
Fill every cell with a sun or a moon, following three rules:
Tap once for a sun, tap twice for a moon. Level 1 walks you through it step by step.
A symbol placed where the solution has the other one costs a heart. You have three per grid. If you run out, simply start the grid again — nothing else is lost.
No, never. Every grid has exactly one solution, and a solver checks before the game ships that it can be reached by logic alone — one row or one column at a time, without ever trying a symbol to see what happens. If you are stuck, look for a line that already holds all its suns or all its moons, or a pair of identical symbols side by side.
It gives you a hint — and it shows you why. Rather than simply revealing a symbol, it often plays the reasoning out on the board: it tries the wrong symbol, walks through what that would force, and flashes the rule it would break. The cells that make the argument light up, so the next time you can find it yourself.
Once you reach level 20, a new puzzle is waiting for you every day. Solve every puzzle of a month to win its trophy. Everybody gets the same puzzle on the same day.
From level 5, every grid you finish scores the hearts you had left, and those points place you in a leaderboard that resets at midnight. Finish in the top three and you win hints and a badge for your collection.
Each one has a switch in Settings, behind the gear icon.
The language of your phone, when it is one of the 17 the game supports; otherwise English.
No. Every level, every daily puzzle and the whole tournament run on your device, and the game is fully playable offline.
Uninstalling the app removes everything it stored: your progress, your collection and your settings. Nothing is kept on our side — see the Privacy Policy.
