On September 6, 1998, Tiger Electronics released a similar game to Brain Warp, a tabletop electronic audio game called Brain Shift. Players move a 'stick shift' in response to voice commands to complete color and sound patterns, and the game becomes increasingly fast. The game requires close attention, and teaches children to recognize and replicate patterns. It came second in the 1998 Duracell Kids' Choice National Toy Survey, and gained a "Seal of Approval" from the US-based National Parenting Center. The hype around the release by Tiger Electronics of the Furby at the same time allowed the company to concentrate its marketing on Brain Shift. This game has two different versions of introduction. It either says "Ok, listen up" or "Alright!" followed by its catchphrase, "Get your brain in gear and let's play Brain Shift." This game has six colors: red, green, yellow, blue, orange and white. The game will then say "Now choose your game". Some units of Brain Shift glitch on low batteries and cut out "your game" with a "you shift". and there are six different games: After choosing a game, the voice will then say "Now how many shifters do we have?" The number of players will be selected and then the game will give a short explanation of how the game is played and then the game will commence.
