Each question is multiple-choice, having four choices. Unlike a traditional quiz where you pick one answer, however, it is possible for you to hedge by placing money on multiple answers in proportion to how confident you are on the answer.
After the answers and question have been read out, you have 30 seconds to move your money onto trapdoors corresponding to the answer(s) you choose.
If you are sure of their answer, you may choose to stop the clock before the time limit is up to carry on with the answers.
After the end of the time limit, the trapdoors relating to incorrect answers open, and any money placed on those answers is no longer available to be won. In addition any money not placed by the end of the time limit is also lost.
If you have any money left, you proceed to the next question where the process is repeated. However, if you lose all money, you are out of the game.
