Master of Code is a print & play game of number logic and deduction for 2-4 players. The goal is to be the first to figure out what 6 digit code the other players have. You do this by asking questions regarding sums, differences and position of the numbers. However, the opponents can also block you from asking a specific question if they feel it gives away too much information or perhaps want to bluff you. But be careful, if you guess wrong you will not know which code you got wrong and have to stay out for a couple of rounds. —description from the publisher
