It is based on Master Mind! If you google something like "play master mind online" you will probably find a lot of websites which will give you puzzles.
The biggest difference, is that in Monster Mind the guesses are all made for you -- so you have to be very clever and very efficient! When you play online, you can make a lot of silly guesses and you will probably always win, even if you are not very clever.

OH and a little easter egg, but this specific puzzle is the reason why I have 5-peg puzzles in my game! I laughed at how hard it was to solve these puzzles with 5 pegs and only 6 guesses. But with Abra's help, I now understand it's actually one guess too many. If you're clever, you can always solve it!
