Just finished building a fully functional and playable minesweeper map in my community world ENDLESSFOREST, feel free to check it out! Its quite hard, and if you have trouble finding a safe starting spot, the bottom two corners are almost always safe spots, have fun!
This took me about 6 hours to build, if you want a fun day-long challenge, Its quite fun to build yourself! While I recommend trying it yourself, you can also use VIP to see my wiring.
