The game is based around a floor divided into a grid of squares initially each representing a different contestant with expertise in a different trivia category.
In the original Dutch version, 100 contestants compete over the course of an entire season, standing in separate spaces of a 10x10 LED grid displayed on the studio floor.
The first contestant whose clock runs out is eliminated from the game with no winnings, and the victorious opponent claims all territory held by that person in addition to their own.
They may then either challenge another adjacent opponent or return to the grid; in the latter case, a new contestant is chosen at random.
The last contestant standing at the end of the season takes the entire floor and wins the grand prize of €100,000.
