## What is opensweeper?

The classic mine-sweeping puzzle. Reveal every cell that is not a mine. Each number tells you how many mines touch that cell; use them to work out where the mines are and flag them.

No ads. No tracking. No accounts. No in-app purchases. opensweeper never touches the network. You can play it in airplane mode.

HOW TO PLAY
• Tap a cell to reveal it. The first tap is always safe
• Press and hold to place a flag
• Tap a revealed number to clear its neighbours once its flags are placed
• Tap the face to start over

THREE DIFFICULTIES
• Beginner: 9 x 9, 10 mines
• Intermediate: 16 x 16, 40 mines
• Expert: 30 x 16, 99 mines
• Optional question-mark flags

FITS YOUR SCREEN
• Play upright or sideways, on iPhone or iPad
• Expert's wide grid stands upright on a phone held upright, so the cells stay as large as possible
