Set: The Game of Visual Perception
It is a fast-paced game that allows one to use logic to the spatial array of patterns using both right and left brain thought processes. The game's object is to either make a set of all the same shapes, shading, number, or color or all different. The first player to see the set — calls out "set" and grabs all the cards. The player with the most sets wins.
Set is recommended for 1-6 players and ages 8+.
