Minesweeper
PuzzleWorks on a phone
Play Minesweeper online on beginner, intermediate, or expert. The first click is never a mine. After that, the numbers are the only warning you get.
Numbers count the mines next door. Right-click plants a flag, and a long press does it on a phone. Both mouse buttons on a number clear the safe squares around it.
Beginner is a 9 by 9 field. Expert stretches to 30 columns and 99 mines. The face deals again.
How to play
Click a square to open it. Right-click to plant a flag, and hold a square on a phone. Press both mouse buttons on a number to clear around it. Game switches beginner, intermediate, and expert. The face deals again.
