Remember Mastermind? The code breaker game? I have made a version using google sheets. I've designed several heart pumping variants for real time head to head play. Current variants include:
-Solo
-head to Head (up to 3 simultaneous opponents can win based on speed or turns)
-Panic
-memory
-fair start
Who wants me to share the file with them? We can get a little 3 player action going and is live some feedback from this great community even though this is technically a computer game, it is really a board game design at heart!!
