Brain Warp
The game was the most popular in Duracell's Kids' Choice National Toy Survey in 1996. During the manufacturing process, there were some units of Brain Warp that contained an earlier revision of the game. The earlier revision was able to cope with faster speeds between 36-44 points on the three reflex games, Colors, Numbers and Combo than the original revision. The revision also had some unused sound files in test mode and had a different background music compared to the newer revision. Also, there was a bug in the older revision that lead to the voice and sound effects not in the right pitch against the music. This also happened with Hasbro's Bop It Extreme and Tiger's Boogey Ball game.
