Minesweeper

Minesweeper is a puzzle of deduction. Clicking a cell opens it, and a number tells you how many mines touch that cell, counting all eight neighbours. Empty cells open their neighbours automatically. Flag the cells you believe hold mines and use the numbers to shrink the set of possibilities. One wrong click on a mine ends the game, so the safe move is always one the numbers prove.

• Click a cell to open it
• A number counts the mines in the eight cells around it
• Flag the cells you believe are mined
• Use the numbers to work out which cells are safe
• Clear every safe cell without hitting a mine

Click a cell to open it; use the flag control to mark a suspected mine.

• Never guess while a number still has a forced answer
• A 1 touching only one unopened cell marks that cell as a mine
• Keep opening the edge of a cleared area for new numbers
• Count the flags around a number before opening more cells

• Classic Minesweeper rules
• Number hints count adjacent mines
• Flag any cell you suspect
• Short rounds, quick restarts
