Build your DFS lineups with a swipe. Optimal DFS turns lineup building into a deck of cards. Every card is an optimized DraftKings Showdown or FanDuel Single Game lineup, best projected first. Swipe right to keep it, left to pass, then export your lineups straight to DraftKings or FanDuel. No spreadsheets. No guesswork. Just swipe. HOW IT WORKS 1. Set your rules: how many lineups, how different they are, which stacks to allow and your salary range. 2. Swipe: every card is a legal lineup with its captain, projected points, salary, stack and exposure. Right keeps it, left passes. 3. Export: get an upload-ready file for DraftKings or FanDuel, checked before it's written. SWIPE BUILDER - Swipe a few, then tap Fill the rest to keep the next best lineups until your set is full. - Choose your spacing: Diverse, Balanced or Top Projected. - Leave out any stack, like 5-1 or 4-2, set a salary floor, and see how many lineups still fit. - Lock a player into every lineup or out of all of them, as captain or flex. - Edit any projection before you swipe. - Track captain and player exposure as you go. - Undo a swipe, or take a second look at the lineups you passed. - Import your DraftKings entries file to fill every contest you've entered, then upload it on DraftKings' Edit Entries page. CLASSIC OPTIMIZER For classic slates, the optimizer builds up to 150 lineups in seconds. - Lock, exclude and edit player projections. - Set max exposures for players and roster spots. - Stack your QB with RBs, WRs or TEs, and keep opponents away from your defense. - Optimize for tournaments, and filter by injury status or projected starters. - Export lineups to CSV for DraftKings or FanDuel, with lineup summaries and player exposures. - Check spreads, totals and projected box scores for every game on the slate. NEVER MISS A SLATE Turn on notifications and we'll let you know when new slates and projections are ready to swipe, plus breaking news that moves lineups.
