About this game

Fill the grid with suns and moons! Lunisol is a calm binary logic puzzle: every level has exactly one solution, and you can always reach it with logic alone, no guessing.

HOW TO PLAY
• Each row and each column holds 3 suns and 3 moons.
• No more than two of the same symbol may sit side by side.
• An = sign means two cells match; × means they are different.

HINTS THAT TEACH
Stuck? A hint explains the next logical step and highlights the cells it follows from, so you learn the technique instead of just getting an answer. Mistakes light up as soon as a rule breaks, or you can turn that off in Settings for a pure challenge.

150 LEVELS, THEN ENDLESS
Start with gentle warm-up grids and work up to expert logic puzzles with only a few symbols given. After level 150, new puzzles are generated right on your device, so there is always one more.

PLAY YOUR WAY
• Undo, restart and a timer with your best time for every level
• Progress saves automatically
• Play offline, no account needed
• 9 languages

A relaxing brain teaser for adults and teens who enjoy Sudoku, grid puzzles and other brain games: easy to learn, satisfying to master. Unwind with a quick grid or train your brain on the hardest ones.

The game is free, and there are no ads in it yet: ads will be available later. Hints are unlimited on the first 10 levels; after that, each level has 3 free hints, and once ads arrive, a short video will give you one more. A one-time "No ads" purchase makes every hint free now and keeps ads away later.
