Twister is a game of physical skill produced by Hasbro Games. It is played on a large plastic mat that is spread on the floor or ground. The mat has four rows of large colored circles on it with a different color in each row: red, yellow, blue and green. A spinner is attached to a square board and is used to determine where the player has to put their hand or foot. The spinner is divided into four labeled sections: right foot, left foot, right hand and left hand. Each of those four sections is divided into the four colors. No one can share the same spot on the mat.
