3Sum League

Every player.
One shot.

Set your lineup every week from a roster your league defines. The catch: each player can be used only once all season.

How it works

Your league, your roster

The format. The classic QB, RB, WR, TE, or your own mix of slots. Commissioners define the weekly lineup. No benches, no waivers, no trades.

Each player, once

The catch. Use Mahomes in Week 3 and he's gone for the year. Once a player is used, he's burned. Every pick is a resource-management decision.

Real scoring, live

The payoff. Points from real NFL stat lines with per-game bonuses, a live scoreboard on game day, and season standings.
