I came across this app after doing research about the TV show "Are You The One?" What's the connection, you might ask? Well, the show is basically one large, interactive human game of "Mastermind". And this app is modeled after that classic board game, "Mastermind". I play this app daily and have mastered the 3-ball and 4-ball levels. It's amazing how this game can train your logic and deduction skills. I'm practicing so that I can "amaze" my young son with my code-breaking skills. He'll have no idea what hit him when we play in a few years, muwahahaha!!!

I like games where you don't have to think a ton to figure things out, but just enough to make you feel smart. I've never tried the hard version yet, but so far it relaxes me, and it's addicting. I feel a sense of accomplishment each time I beat my own goal. I gave it ⭐️⭐️⭐️⭐️ is because I think it would be even more exciting, if we could keep track of our scores, as well as other players scores. Maybe even a daily challenge, similar to what they do for the solitaire app I play. Anyways, I would highly suggest this game for the simple minded, who enjoys feeling smart and relaxed at the same time.

A terrific version of the game Mastermind I played growing up. I like that it's easy enough to win so I feel smart but tough enough I need to concentrate to do it. Agree with others about the gray & white buttons. Until you have both colors on the board to compare it's difficult to know which one you've got.

I have played this game for many years and found it to be reliable, as well as lots of fun. But lately, for some unknown reason, it occasionally shuts down the game in the midst of my play. I lose whatever progress I’ve made on that game and have to start a new one. Please look into this. I don’t see a version number of the game, but it automatically updates, along with other apps. I am on the latest iOS on both my iPhone 7 and my iPad Air. Thanks!
