Playing in teams, or individually, players try to guess the correct answer from one of 816 questions arranged into three levels of difficulty.

Points are awarded for the difficulty level and the team with the most points at the end of the game is the winner.

A sand timer ensures that no-one takes too long, and the ability for different teams to work at different difficulty levels means that contestants can still be competitive when coming from differing ages and experience.
