Dab Hand says: Grand Mastermind is described as the most difficult version yet of the classic code-breaking ‘game of cunning and logic’. Players take turns to set a code of 4 shape counters and 4 colour counters for their opponent to solve. The player who cracks the code with the fewest attempts wins. A second more advanced version of the game offers the equivalent challenge of using 6 code shapes and 6 colours! The contents are in pristine condition and 100% complete as itemised on the instruction pamphlet. The shape counters are still affixed to their plastic holders, meaning that this copy of the game has not been played. The box is in good condition for its age with some minor wear and tear around the corners and edges. Overall, this is an excellent example of this 1974 game. We love the 1970s evening dresses on the box cover!
