Fill the grid with suns and moons using balance and match clues. Three sizes, a daily puzzle, works offline. SunMoon: Binary Logic Puzzle Game Fill a grid with suns and moons until every rule falls into place. It's a quiet kind of puzzle — no timers pressuring you unless you want them, no ads interrupting your thinking, just a grid, a few rules, and the satisfaction of watching everything click. Here's how it works: place a sun or a moon in every cell so that no row or column ever has three of the same symbol in a row, each row and column ends up with an equal number of suns and moons, and any "=" or "×" chip between two cells is respected — matching cells for "=", differing cells for "×". Simple to learn, surprisingly deep to master. Three grids to choose from Start with the 6×6 for a quick breather, move up to 8×8 when you want something meatier, or take on the 10×10 if you're after a real sit-down session. Each size is generated to have exactly one valid solution — no guessing games, no dead ends, just logic. A daily grid for everyone Every day brings the same 8×8 puzzle to every player, so you can compare notes with a friend or just make it part of your morning routine. Complete it to keep your streak alive — miss a day and the streak resets, so there's a little accountability built in. Hints that respect your time Stuck? You get a few hints per puzzle. If something you've placed is already wrong, the hint will point that out first. Otherwise, it'll fill in one correct cell for you. Solve without touching a hint and you'll see it reflected in your stats. Everything else you'd expect Undo and redo without any penalty. A pause button that actually hides the board, so stepping away doesn't mean losing your place — or being tempted to keep studying it. Light and dark themes that switch instantly. Full keyboard support for anyone who prefers arrow keys and shortcuts over clicking. And a stats panel that tracks your streak, your fastest times per grid size, and how many puzzles you've solved. Built to stay out of your way Everything runs entirely on your device. There's no sign-up, no account, no internet connection required once it's installed, and nothing about your play is ever sent anywhere. Your progress, your records, and your streak all live locally in your browser. If you've ever enjoyed a good logic grid over morning coffee, this one's worth keeping in your toolbar.
