Brain Quest is a series of educational flashcards that quiz children on a variety of subjects including science, math, English, geography, history, and others.
It sold 4.2 million copies in its first 16 months,[1] and made The New York Times Best Seller list for children's books.
[vague] LeapFrog Enterprises designed and released a special Turbo Twist handheld toy that is based on the Brain Quest license.
Similar to the original flashcard product, the player must answer multiple choice questions based on science, social studies and/or language arts, by "Twisting" the end of the unit to select answers and "Slamming" a button to choose the correct one when it is displayed.
The player can choose from ten levels of difficulty and also encounter questions from all three categories, called the "Grab Bag", like in the original flash card game.
