This lovely incarnation of a game we played in the 80s includes more than 6 colors, more than 5 spots to solve, and limitations for the harder levels on using the same color. The hardest level is "Insane," but after some months, there are methods to solve under two minutes with a little luck and multiple tries (no, a real winner doesn't try the same level twice in a row!). Anyway, letting us review our attempts (like it used to do) to train logic should be an option we can turn on in settings

I wish it would be more like Classic Mastermind with the option of four slots and repeating colors. There are lots of options but not that one.

A fun game that I played as a kid. A pretty good version, although I agree with others it would be nice to hide/unhide rows. Also, a warning that you've already entered that combo would be nice, too, especially as the board gets longer.

Awful. Just downloaded it. Played one game. No way to get out. Had to restart my phone. If I had to call 911 but had to restart the phone just to get out of an app ... !! I have had to call emergency a few times lately for family, so I'm not taking chances. Trashing this immediately.

The idea of multiplayer mastermind is nice but the UI is terrible. It mixes the two games and the time makes it impossible to think it through. Also there are bugs. Sometimes there is no code possible 6 pegs 7 colors 4 gave nothing and the remaining 3 only used 4 (I have screenshotted to show it) positions. Absolutely not ready to be on the market

Once you chose "empty peg" and "duplicate peg" you can't change it. Why?
★★☆☆☆R Mix· May 17, 2025
In multiplayer, not often, but sometimes the opponent has a different color that ends up being one you can't even use. So you have zero way of winning. How has nobody fixed this. Aside for that it'd be great. But that ruins the game.
★★☆☆☆Sander Bouwhuis· Aug 8, 2025
It looks good, but it doesn't seem to have a simple standard game mode where the computer randomly chooses a combination for infinite replayability. Uninstalled, I will try another Mastermind game.
