Set in a retro-futuristic universe, the game concerns Polly Spark, the bratty daughter of an apparently very wealthy inventor, and her attempt to alter history so that her inane answers to a history quiz she failed will be correct. It is currently included as the 'Fundamentals' disc of JumpStart Advanced 3rd Grade. This is the only version of this game created and, unusually for Knowledge Adventure, is still being sold over fifteen years after its initial release in 1996. As the title suggests, the game is intended to teach a third grade curriculum.
JumpStart Adventures 3rd Grade: Mystery Mountain is a personal computer game in Knowledge Adventure's JumpStart series of educational software.
