Codebreakers, for most of you, should be quite easy. You will start with four stones. Your objective is to guess the stones sequence and colours within ten steps.

The Stone Colors
Here is how the stone colours progress -clicking a stone will change its colour

Meaning of Marks
No marks = nothing right
White marks = colour right but position wrong
Red marks = Same colour and position as the master stone(s).

How to do it
I basically just start off guessing all red
If none are right, change all the colours to white
If some are right, leave the number that are right, and change the rest to white
Progress thru the colours and you will eventually find them all!
