Pairs of contestants face each other in head-to-head trivia duels, with the winner taking over all territory controlled by the loser.
The game progresses over the course of a season with the grand prize of €50 000 awarded to the player who ultimately controls the entire floor.
[1] Secondary prizes of €2 500 are awarded throughout the season to the winner of the final duel with the two players with the most territory at the end of each episode.
The season begins with 100 contestants standing in separate spaces of a ten-by-ten grid on the studio floor.
One contestant is chosen at random and shown the categories of all opponents whose territories share at least one edge with their own, then the player chooses one of them to face in a head-to-head duel.
The two contestants take turns identifying a series of images, words, or sounds associated with the challenged opponent's category.
Multiple guesses are allowed without penalty, and a contestant may pass whenever desired; however, they must wait three seconds for a new image, text, or sound to be shown.
The first contestant to run out of time is eliminated from the game and gives up all of their territory to the winner, who takes/retains the challenger's category.
The winner may then either challenge another opponent or return to the grid; in the latter case, a new contestant is selected at random from those who have not yet played a duel.
At the end of each episode, except the last one, the two contestants holding the most territory will battle in a final duel with a mystery category.
The last contestant standing at the end of the tenth and final episode of the season wins the grand prize of €50 000 .
