Color Decryptor - Mastermind

You have to solve code.

Use coloured pins to find out what the code is. Decryptor will tell You how many of those pins are in the code. Try to solve it in as less try-outs as possible. If You don't do it in 12 rounds, you lose.

Start from Easy level to learn how it works. An keep practicing. Maybe one day You will be able to solve code on Hard level.
