These are very cheesy games (but that probably has a lot to do with their age). Each one is exactly the same in gameplay and scoring: you press play, the computer randomly selects and lights up one of the 6 LEDs, and you manually adjust the score wheels appropriately. I currently know of six of these (all sports games except Space Shot): Baseball, Basketball, Bowling, Football, Hockey and Space Shot. They are kinda cute though, I was expecting them to be about the size of a Mattel Football game or something, but they are actually about the size of a common handheld LCD game, a lot smaller than you might think.
