The Floor is a physical quiz show that sees 81 contestants face off in quiz duels on a giant LED floor divided into a 9×9 grid of squares, each representing its own field of knowledge.

The first challenger, selected at random, must choose one of his or her neighboring opponents to go head-to-head in an epic quiz duel in the opponent's category. The winner takes over the loser's square, gaining valuable ground as they expand their territory, while the loser exits the game. The winner must then choose – do they continue on and attempt to secure another square? Or do they let The Floor choose a new challenger? The last contestant standing who gains full control over The Floor takes home a life-changing $250,000 cash prize.
