Click to place, click again to change color. The goal is to discover the hidden combination of colored pegs.
Start on the bottom row, and choose a combination of colored pegs (click once to position, and again to change color.)
You will then be given black or white clues on the right hand side.
Black = correct color, correct position. (You want to have five of these to win!)
White = correct color, wrong position.
Try different color combinations and use your brain to figure it out, before all your moves are up!
