This is not so much of a game as a device for simulating a test match. The board holds a score board and two rotating randomizers. The bowler rotates his handle to first ball of the over and back to the start, revealing a type of ball (leg break, bouncer, etc). The batsman rotates his handle to the type of ball bowled, and back again, revealing a batsman scoring runs or being dismissed. If you know the rules of cricket, it's obvious how to simulate a test match given these rules.
