It is good old Minesweeper puzzle game but on infinite desk.
If you are lucky to have a PC, you can just use left and right botton on your mouse.
If you have mouse or something like that, but you have no right buttom, you are to hold one of the modefier keys to emulate right botton. Try one of these: Command ⌘/, Control Ctrl/⌃ or Shift Shift/⇧.
If you use touchscreen device, try to obtain right click by tap with second finger.
