Code breaker - decoding

Code Breaker is a logic and deduction board game. It is played between two players, one of them is the encoder, the other is the decoder.
The rules of the game are as follows:
1. The encoder selects a secret combination of 4 colours (from 6 available) which they place on a support.
2. The decoder must guess the secret combination by making attempts placing combinations of 4 colours on another support.
3. After each attempt, the encoder informs the decoder of the number of colours correctly placed and the number of colours present in the secret combination but incorrectly placed.
4. The decoder must guess the secret combination within a limited number of attempts, usually 12, and each colour can only be used once.
5. The decoder wins if they guess the secret combination before exhausting all attempts, otherwise the encoder wins.
