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. While the chart is shown, press W to change the colors. Press Q again to hide it.
If you have a red, green, blue, and white mine, they cancel each other out! The number will be 0, but it will be a different 0 from the empty tiles. Adding mines to that 0 works like adding mines to an empty space, so a red 1 could be either 1 red mine or 2 red, 1 green, 1 blue, and 1 white mine. It is safe to reveal 3 spaces around a tile, because it needs 4 spaces to cancel out.
