Click on cells and flag the mines with Spacebar. Ordinary stuff like you usually need to do, but there are more than 1 mine in a cell, and more numerals up to 48.
Changes between original Minesweeper: - More mines, more difficulty (not for beginners, difficulties were not implemented) - Smiley clicked variations If you can, help me revealing all the cells when clicking on empty cell in the zone where you clicked, win condition and safe first click upon my code. Would appreciate that.
