The object of this puzzle is quite simple, all you have to do is to rotate each of the six numbered rings around the central pin so that each straight ‘line’ of six numbers from that on the bottom disc to that on the top disc when added together totals 100! A great family leveler and one that provides everybody with a real incentive to get to grips with some mental arithmetic. Revolving-Century-375
