01
Draft a squad
A fresh $1,000 play-money bankroll each round — pick your players across the fixtures.
02
Set your own lines
Over / Under or a Range on each player's fantasy score. The sharper the read, the bigger the payout.
03
Best return wins
Highest net return tops the round; best across the competition takes the grand prize.
Set your own line

Two ways to call it.

Every pick is a set-your-own-line trade. Accuracy and direction pay differently — so the sharper the read, the bigger the return.
