Optimizer

Our NFL Optimizer is a tool that will allow you to optimize or build hundreds of lineups at a time. You will have access to advanced settings or even simple “1 click correlations” that will help you generate lineups for the contest of your choosing (GPP, Single Entry, Cash, etc). The optimizer is where you “pull the levers” of the slate to build teams that you want. If you want to learn more:  Short Overview | Tutorial on Advanced Settings

Simulator

The Solver NFL DFS simulator takes a lineup (or up to 500 lineups) and simulates them in a DraftKings or FanDuel contest. This will give you a variety of info about the lineup(s) such as; its projected ROI, mean and ceiling projections, projected cash rate, and a distribution of the lineup’s finishing position in the simulated contest. For more information and a video see our Simulator FAQ. The purpose of the simulator is to use it as a tool for finding how lineups perform in a certain contest.
