DFS Optimizer

Build DFS lineups for any contest, in seconds

THE SOLVER Optimizer is a tool for building lineups for DraftKings, FanDuel, and other DFS sites. Pick your projections, set the rules you want for stacks, correlations, and exposure, and it will build anywhere from one lineup to 1,000 for you. The included Lineup Builder makes up to 3,000 lineups quickly with fewer rules.

Built by the team behind THE SOLVER, a group of longtime fantasy players and software engineers. Works for 10+ sports and 5 DFS sites.

What can the Optimizer do?

Here are the three main things the Optimizer does.

Build at scale

Generate one lineup or up to 1,000 in a single click, then save, tag, and export them in seconds. Need more volume? The included Lineup Builder makes up to 3,000 lineups quickly with fewer rules.

Your projections, your edge

Start with built-in Default projections (available for most sports), upload your own, or sync a partner’s — and switch between sets instantly.

Rules that enforce your strategy

Quick Rules for one-click stacks and correlations, or advanced rules for exposure, boosts/docks, and precise stacking.

From projections to entry-ready lineups

1

Load your players

Start with our built-in Default projections (available for most sports), upload your own CSV, or sync a partner’s projections — for NFL, NBA, MLB, NHL, Golf, and 10+ sports across dozens of leagues.

2

Set your rules

Use Quick Rules for one-click stacks and correlations, or build advanced rules for player exposure, boosts/docks, and precise stack requirements.

3

Build and export

Build one lineup or up to 1,000 in seconds, then export them to DraftKings, FanDuel, Yahoo, and other sites. When news breaks, you can late swap them in one click.

The Optimizer handles the math, so you can spend your time deciding which players and stacks you want instead of building lineups by hand.
