Reveal all safe cells on a board with hidden mines.
Rules
Tap a cell to reveal it. Numbers indicate how many of the 8 adjacent cells contain mines.
Place flags on cells you believe contain mines. Long-press or use flag mode.
When a number cell has the correct number of surrounding flags, tap it to reveal the remaining cells at once.
Revealing a mine ends the game. Reveal all safe cells to win.

Start from edges and corners — fewer adjacent cells means easier deduction.
The 1-1 pattern: two adjacent 1s in a row means only one side has a mine.
When unsure, place flags first to secure safe areas.
Minesweeper is an NP-complete problem combining logical deduction and probabilistic judgment, effectively training deductive reasoning and working memory.
