I recommend this app to both beginners and Mastermind enthusiasts alike. The app currently is player vs. computer, with the computer setting the code and the player solving it. The game board closely resembles the original Mastermind board, and it has the traditional six colors. Options are: 1) Easy (no color is repeated in the code) and hard (a color may appear twice) modes, and four or five holes. The app runs smoothly, and the user interface is easy to use. The player may drag a color directly to the desired hole or simply touch it and have it go to the first open hole. There is a hint mode available that reveals the color for a random location. The game also keeps stats for how well a player does over time. There are no ads on the game screen itself. There is an occasional ad between games and when asking for a hint. There is an in-app purchase of $1.99 to remove all ads, and I recommend that anybody using the app regularly pay it to encourage the developer

This is not mastermind, not the way you can play it in the original game

For some weird reason which is probably only known by the developer him/herself, the app does not allow me to enter more than 2 gems of a given color. Sometimes I will fill all 4 spots with a single color which can give additional clues to previous steps. For that reason I will need to uninstall the app and try another Mastermind clone. The app looks good though.

DO NOT DOWNLOAD THIS APP, IT IS NOT MASTERMIND, JUST A CHEAP IMITATION. SO MANY ADDS EVERYTHING YOU TOUCH BRINGS UP ANOTHER ADD, YOU MUST PAY TO REMOVE THEM EVERY TIME YOU PLAY BECAUSE THEY'LL COME BACK EVERY TIME YOU RESTART THE APP, OR IF YOU TAKE TOO LONG TO MAKE A MOVE, OR JUST PAUSE LONG ENOUGH TO LIGHT A CIGARETTE AND IT JUST STARTS RUNNING AN ADD. SAD HOW GREED HAS CONSUMED THE DEVELOPERS WHO PROBABLY SIT AROUND AND ARGUE AND FIGHT ABOUT SPLITTING UP THE PENNIES PER ADD.

Ads. Edit: I know how ratings work, and I know how ads work. Everyone does, obviously. But there's a right way and a wrong way, and your low tier, unoriginal app is doing it the wrong way. The rating stays.
