20Q

The 20Q is an amazing guessing game developed by software maverick Robin Burgener, who came up with the idea back in 1988. After experimenting with neural networks, Burgener developed an online website to play the game 20 Questions. This site was a huge success and led him to develop a toy with the power of 250,000 neural synaptic connections.

The 20Q game learns as it goes, and it can hold a tremendous amount of information in its memory. The game can guess very unusual items. Children can spend hours trying to trick the 20Q into messing up, but the game does a good job of breaking even complicated codes. The 20Q fits in a pocket and requires two AAA batteries. Avid game players may want to stock up on extra AAA batteries.
