36 hours, 12 rounds, about 200 builders, one name. Paris. No second place.

HOAT brings everyone who thinks they’re the best builder in Europe into one room in Paris, with the best sponsors behind them. Then the clock runs for 36 hours, and only what ships counts.

Twelve rounds.
Thirty-six hours.

Three hours a round. The bell never stops, and neither do you.
