The concept is like the game Twister, but you use the ABCs with corresponding "right hand, left hand, right foot, left foot, ear, etc." It gets pretty crazy! In addition to the ABC's the game will use things that start with the letters so that you learn your beginning letter sounds.
This game is great for reinforcing ABC and beginning letter sound concepts, I love it! Also, who wins the game is actually decided by chance, which I always find to be a nice thing with young children. All in all, this is my favorite game that I have purchased for my kids!
