Ratings and reviews

as someone who loves the board game, this app has not only done it justice but has gone above and beyond with the elements that have been included. I love how you can change the number of slots, it's great for those of us who want to test and push ourselves. The scoring of how useful the guesses are and the number of possible codes on each guess is something that i love considering with the board game and it's so fulfilling for me to see it accurately calculated! I admire the app creators mind!

This is brilliant. If you want to get better at this game, or simply develop your logic and deduction skills, this is the app for you. The UI is a little difficult to use, but hey. It's very small on the phone but I'll try on my tablet and see. Thanks for the hard work.

I break these codes myself no Ai. Started with Super MasterMind about 45 years ago when it took two people to play it!! Code was 5 colors long and 12 tries. Start with one color at a time and use logic. Have fun! 😀
