If you have ever played Mastermind, you will be familiar with the object of Colour Logic. The computer has in mind a sequence of five colours and you must try to guess what they are, in the correct order. Key in a sequence of your own - Y for yellow, R for red, G for green, M for magenta, C for cyan, B for blue, W for white - and the computer will give you a white star for any colour which is correct but not in the proper place, and a green star for the proper colour in the correct place. You have 14 rows to determine the answer by a process of elimination.

Press RETURN to change a row you have just entered, and N to go on to the next row.

Attractive, clear graphics add to the appeal of this absorbing, if scarcely original, game.
