This is a great game. My kids came home from school and they had been doing this in PE class and they loved it. This toy came out in 2006 and was one of the top toys. It comes with the mat, 12 cups with a bag for storage and the speedstack control panel.
Basically, the control sits on the mat in its place and you put your palms on the control panel which it reads some how and it starts the timer. The goal of the game is to stack the cups in different sequences(that comes with the game) in the fastest amount of time. This is great because it makes your brain work which for most kids their brain working is usually with tv of video games.
You can buy additional cups both in different colors and glow-in-the-dark so as you get better you can make bigger and bigger stacks and sequences.
I woudl recommend this game to everyone, the entire family because even as an adult it is alot of fun to play. I know because I play it. You can get it just about anywhere. When we purhase ours it was around $30.
