The Challenging Game of Logic and Deduction. The object: your opponent has set up a hidden code. You must guess which color pegs he¹s used and the order he¹s placed them in. With over 2000 combinations possible, Mastermind® is a challenge every time you play. Mastermind® for Kids also has a secret code game scenario but uses color-coded jungle animals instead. Young players simply guess which animals are hiding while older players must guess the order they¹re in too. Both games are for 2 players. Mastermind® is for ages 8+. Mastermind® for Kids is for ages 6+.
