Hello everyone,
I need help on this program I have. It's a matching game.
I want to add the bomb feature like in minesweeper but it doesn't seem to stay with the square its located in.
Also I would like for the game to reset if you click on the bomb, and if you click on the bomb three times you lose.
Please help asap, thanks in advance!
