Custom Minesweeper
Custom lets you set the board yourself: any width and height from 6 to 32 squares, and a mine count from 10% to 75% of the board. Start below on a 20×24 board with 96 mines, then open the settings to make it smaller, bigger or denser. A large board at low density plays long and calm; a small board packed with mines is a puzzle you lose fast.
Board
Width and height 6–32 squares, mines 10–75% of the board.
Tips for custom
- Around 20% mines is classic difficulty; below 15% a board mostly solves itself, above 25% it needs guesses.
- The biggest board here is 32×32 — 1,024 squares. Zoom in to play it on a phone.
- Use the settings button under the board (the cog) and pick Custom to change the size.
- Same density, bigger board: more patterns, more time, about the same chance of a forced guess per square.
