Classic Mastermind for Android ( with Google Play Game Services). Guess the order of colors chosen by Android. Start by selecting the colors you want on the right side of the screen. After selecting the 4 colors in a row, click the "OK" button to confirm. Check out the result on the 4 smaller balls: - A white ball means you hit the color in the correct position. - A red ball means the color exists but is in the wrong position. You have 10 chances to hit. Tip: Before clicking "OK" you can change any color by clicking in the desired position. Good luck!
