Minefield

Clear a minefield without stepping on a mine. You never have to guess. Solo

How to play Minefield

Open every cell that doesn't hide a mine.

You start with an open area in the middle of the board.
A number tells you how many of the eight cells around it hide a mine.
Hold a cell (or right-click) to place a flag where you know there is a mine. You can also switch on the flag button.
Tap a number once all its mines have a flag, and the rest around it opens.
Open a mine and the game is over.

You win when every safe cell is open. The faster, the better.

Every board can be solved with logic alone, so there is always a safe move somewhere.
Look for a 1 with only one hidden cell next to it: that is where the mine is.
