How to play

• A number says how many mines touch that cell, counting diagonals.
• The first click is always safe — the mines are placed after it.
• Right click marks a cell you believe hides a mine.
• Clicking a number that already has all its flags opens every other neighbour.
• Open every safe cell to win; the timer is your score, so faster is better.

Tips

• Start from the corners and edges: they have fewer neighbours and give cleaner information.
• A 1 touching exactly one unopened cell always marks a mine — flag it without thinking.
• Compare two adjacent numbers: the difference usually points at a safe cell.
• Chord clicking is far faster than opening cells one by one, and just as safe.
