On each episode, four contestants compete to accumulate and win prize money by choosing the best answers to questions and matching them against each other.
All questions used during the game have six answer choices, which are secretly ranked as to how close they are to meeting the criterion stated.
The highest-scoring contestant chooses one opponent to battle; in case of a tie for high score, a random draw determines who will have priority.
If neither contestant presses their button, the face-off proceeds to a series of battles, with two victories required to win the board.
The opponent of that contestant gets first choice of the remaining four answers if the board is not immediately decided, and the one in control chooses first if a third battle is needed.
If the unbeatable answer is not found after five guesses, the contestant who did not have initial control wins the board but does not receive any money.
