I would like to share with you an Excel game that I made back in the day. It is called Mine 3D, and it works like the popular minesweeper game, except that the playing board is “3 dimensional”. The worksheets are protected, but with no password. There is a interesting combination of formulas and programming used in the making of this game. So, feel free to explore how it works. Enjoy!
You can download the Excel game here.
