Plenty of hand held electronic games can be fun but it takes a special game to be both entertaining and deeply unsettling. This small spherical game of 20 Questions looks like it rolled right out of 1979 with a retro design, old arcade style sound effects, and a red light display for its various questions and guesses. Game play could not be simpler. Just think of something and then answer the ball's assorted queries by pressing buttons for yes, no, sometimes, or don't know. In our informal test, the ball accurately guessed our selection of giraffe, motorcycle, and sock but came up a little short on buttered toast. Two AA batteries are required and included. --Charlie Williams
