Rules, hints & daily puzzles
Each number counts mines in its eight surrounding squares (fewer at an edge). Numbered squares are always safe. ◆ marks a mine; × marks a safe square. Tap an already matching mark to erase it. There is no timer or life limit.
Choose Mine or Safe, then tap squares. Undo reverses a mark. Check marks checks your current answers without filling any squares. Hint explains one deduction, highlights the affected squares, and lets you apply it.
Hard cannot be completed using single-clue counting alone. Expert requires at least four overlap deductions in our solver. Master has 7×7 boards requiring at least six. All 144 boards have one solution and a verified deduction path.
Daily offers one board per difficulty, changing at midnight UTC when you return to the tab (also checked every 30 seconds). Standard, Hard and Expert each have 40 boards; Master has 24. Daily repeats after that many days and shares the practice bank. Practice and Daily progress are separate, including difficulty and UTC date. Your latest practice opens on return if saving is enabled. Without saving, records last only for this page visit. Restart and Undo do not remove help usage. Browser data clearing can erase saves; saves do not sync between devices or site domains.
