Research and calculators
Understand the pick before you build the card.
Bring an NFL, MLB, or NBA player-prop line to Research My Pick when an upcoming game and fresh verified data are available, then use payout calculators to compare entry mechanics.
Research My Pick
Choose NFL, MLB, or NBA, then select an upcoming game and an available market. Research a current DFS option or your own editable line when fresh verified data are available. See historical support and research context before you sign in to save it.
MLB Hitter Range Board
Compare current DraftKings MLB fantasy-point floor, projection, and ceiling estimates. Built for range-aware research, not lineup optimization.
Sports Betting Prompt Builder
Build a structured, skeptical prompt that requires current sources, counterarguments, missing-data disclosure, and a no-action conclusion when evidence is weak.
PrizePicks Payout Calculator
Calculate Power Play and Flex Play payouts for 2-6 picks, including 3/4, 4/5, and 5/6 Flex results.
Underdog Flex Payout Calculator
Check Standard and Flex payouts for 2-8 pick entries, including partial Flex outcomes on larger cards.
Pick6 Payout Calculator
Calculate Pick6 fixed multiplier payouts for 2-6 pick entries and compare the payout chart against other platforms.
Compare payout styles before you compare props.
The calculators answer the mechanical question first: what does this entry return if the card hits? Once the payout structure is clear, use Propeller to research which props deserve a spot on the card.
