Every square on the board can be either a normal square or a mine. The number on a square represents how many of its eight neighbor squares are mines. If a square has no number, it is not touching any mines. The goal is to press every normal square without triggering any mines. You can use the flags to help yourself see where the mines are. You can change whether your clicks reveal squares or place flags by pressing the button in the top right corner or pressing the a key.
Mobile Friendly! To start, click any square. Click a to change your click mode. If you are the first person to beat impossible, comment your time, and I will follow you. (I can see who beats impossible via cloud) I am aware that hard and impossible modes take a long time to load. They will load eventually, though. Easy takes about five seconds to load. Hard takes about 20 seconds to load. Impossible takes about 90 seconds to load.
