I got bored with normal minesweeper so I made a 3D one. I don’t have the skill to make 3D graphics, but the structure is three-dimensional.
The rules are basically the same. Press Z and X to move between layers.
That’s a great idea. I didn’t add the modes, but you should be able to change the dimensions yourself to use these modes. One minesweeper site used 16*16*1 with 40 mines for intermediate mode and 30*16*1 with 99 mines for expert mode. I’m currently trying to finish a 10*10*10 minesweeper with 100 mines.
