How Showdown Edge works

From slate to DraftKings upload in a few minutes.

Pick a slate
Today's Showdown games are already loaded with official DraftKings salaries, player IDs, prop-based projections and injury news. Click Refresh live data any time for the latest injuries and props.
Set your rules
Lock players, set Captain-only or exclude, choose stacks and bring-backs, set your Captain mix by position, and decide how different your lineups should be with minimum unique players and max exposure.
Build your lineups
The optimizer searches every legal Captain plus 5 FLEX combination under the $50,000 cap, not a sample, then picks the best lineups for your objective. The ceiling objective is tuned for large-field GPPs.
Simulate
Run thousands of correlated simulations. Teammates and opponents move together the way real games do, and you control the game-script mix: shootout, defensive grind or one team in control. Each lineup gets a top-1% rate and a win-score distribution.
Export and upload
Download the CSV and upload it to DraftKings under Lineups, Upload Lineups. CSV Export Help walks through it.
Learn from the slate
After the game, load actual scores from licensed box scores, see the hindsight optimal lineup and run backtests against real contest results.

Lean on ceiling, not just median projection. The ceiling objective and the simulator's top-1% rate are built for this.
Use ownership estimates to find Captains the field is underplaying.
Correlate your Captain with teammates who benefit from the same game script.
Set minimum unique players and max exposure so a multi-entry set doesn't lean on one outcome.
