- This is small tabletop Mastermind game; a code-breaking game where the player
- needs to find out the correct sequence of colours (numbers in our case).
- It is known as Logic 5 in Europe, and as Pythaligoras in Japan.
-
- Press the R key to start, followed by a set of unique numbers and E.
- Refer to the official manual for more information.
