Code breaker - board game app for iPhone and iPad

Code Breaker is a logic and deduction board game. It is played between two players, one of whom is the codemaker and the other is the codebreaker.
The rules of the game are as follows:
1. The codemaker chooses a secret combination of 4 colors (from 6 available) which he places on a board.
2. The codebreaker must guess the secret combination by making attempts by placing combinations of 4 colors on another board.
3. After each attempt, the codemaker indicates to the codebreaker the number of colors that are in the correct position and the number of colors that are present in the secret combination but in the wrong position.
4. The codebreaker must guess the secret combination in a limited number of attempts, usually 12, and each color can only be used once.
5. The codebreaker wins if he guesses the secret combination before running out of attempts, otherwise the codemaker wins.
