Bozo keeps score for a friend-group parlay. Everybody in the pool submits a leg. The legs combine into one parlay. Whoever's picks did worst is the Bozo, and the Bozo funds the next round. That's the whole game. AUTOMATIC SETTLEMENT Bozo syncs real schedules and final scores, grades every leg the moment its game ends, and works out who's on the hook. No arguing over a half-point. FOLLOW THE ROUND Every leg shows where its game stands, from upcoming to in progress, then turns into won, lost or push as soon as the final score lands. Your pool list sorts itself by whatever is waiting on you. REAL LINES Pick spreads, totals, or moneylines straight from synced sportsbook odds, or write in a custom bet and settle it by hand. COMPARE THE BOOKS See what every major licensed sportsbook and prediction market is offering on the same game, side by side, and spot where they disagree. POOL RULES Admins can set a minimum-odds floor so nobody pads the parlay with a heavy favorite, lock a pool to a single sport, or require several legs per member. STANDINGS THAT LAST Every settled round feeds a running leaderboard, a differential-over-time chart, and a net profit-and-loss column. CLAIM BOZO Watching your leg die early? Claim it, settle the round on the spot, and get the next one started. GLOBAL LEADERBOARD The highest-odds winning parlays from every pool, anywhere, with each leg credited to whoever called it. A second board tracks who has funded the most rounds within a single pool. Bozo never takes payments, holds money, or places bets. It keeps score. You and your friends settle up however you already do. 18+. Please gamble responsibly. If you or someone you know has a gambling problem, call 1-800-GAMBLER.
