HOW IT WORKS
FOUR STEPS. THAT'S IT.
PICK YOUR XI
Browse 11 live Polymarket World Cup markets — tournament winner, golden boot, group stage results and more. Pick one outcome from each. Every pick is mutually exclusive within its market.
GET YOUR CAPTAIN
Tap C on your boldest prediction to make them captain. Your captain earns 2× points if correct. Stack with a 3× multiplier and a single pick can score 6× — your biggest call of the week.
JOIN OR CREATE A LEAGUE
Enter the $10 Global Weekly Jackpot — winner takes all. Or create a private league and compete against friends. Lock early for a 1.05× score bonus. Your lock timestamp is the tiebreaker.
