A recreation of minesweeper? Yes, I decided it's finally time. Now with an explanation:
The goal is to click everything but the mines. Clicking a mine causes you to lose!
The numbers tell you how much mines are around it, including diagonals.
Pressing space places a flag on the tile. Flags are used to mark mines. Tiles with flags can't be clicked. To remove a flag, press space again.
Variation specific:
Space puts a red flag down. Press space again to switch it to green. Space again to switch it to blue, again for a white flag, and again to remove the flag.
Pressing Q shows a chart that should (hopefully) make you understand what's going on.
