Mastermind Code Breaker

你能破解密码？你是主谋？

With up to five digits in the code and up to eight colours to choose from this app guarantees you will be playing and breaking codes for hours. You will have to keep practicing if you want to be a champion. There are three game modes available: easy, medium and hard.

After each guess you will be given a clue as to how close you are to completion. A black dot means one of your colours is in the correct position. A white dot means one of your colours is in the code, but not in that position. The order of the dots is not important.
