Spin & Trap is a strategy game that's easy to play but impossible to master! Using "rotators" to change the position of the marbles on the game base, players attempt to "trap" a green marble, surrounding it by all white or all black ones. Both offensive and defensive strategy is needed to win. This is a great family game - an 8-year-old can be just as successful as an adult! The contents of this game include a game board, 21 marbles, 3-marble rotator, and a 6-marble rotator. The underside storage compartment holds all of the marbles. 2 Players. Recommended for age 8 years and up.
