This double games cassette for the unexpanded Sord M5 contains Three Circles and Number Search.

Three Circles is described as an original version of the three circle game and is a contest between your brain and the computer's CPU. You must consider your move as well as your opponents. I'm afraid this is all I can say about this game since I found the instruction booklet totally incomprehensible.

Number Search is a simple version of the once popular game Master Mind by Invicta Plastics. If you've been living in an underground shelter for the last 50 years, you won't know this game so let me explain. The purpose of this game is to find a special number generated by the opponent - in this case the computer - by using the fewest possible hints. In this version you choose the number of digits and the computer gives the hints.

These are two trivial games which don't exploit the capability of the M5 to any extent. This is surprising since all the other double cassettes are fairly good but I honestly cannot recommend this.
