Crownfall: Logic Grid Puzzles

Crownfall is a logic puzzle where you place crowns on a colored grid using pure deduction — no guessing required. The rules are simple to learn: on each board, place exactly one crown in every row, every column, and every colored region. No two crowns may touch, not even diagonally. Every puzzle has exactly one solution, and it can always be reached by logic alone. Features - Five grid sizes, from a gentle 5×5 up to a 9×9 challenge - A daily puzzle that's the same for everyone each day - Tap to cycle a cell between empty, a mark, and a crown - Optional auto-marking to block out cells around a placed crown - Undo, redo, and up to three hints per puzzle - Live conflict highlighting so you can spot mistakes as you go - A built-in timer, plus streak and personal record tracking - Light and dark themes - Keyboard navigation and reduced-motion support - Full-screen mode for a bigger board Everything runs on your device and works offline.
