Code Breaker description

Can you work out the secret code by placing colours in a row?
To help you out, each time you complete a row lights will be illuminated to show how close you are to the correct code.
A green light means that one of your choices is perfect.
A red light means that one of the colours is correct but in the wrong location.
Your score will be determined by how fast you can crack the code and how few attempts you make.
