Underdog
Covered todayUnderdog Fantasy is a fantasy product whose higher and lower pick'em entries are the part Slateline reads, separate from its best ball drafts.
What Slateline can do here
- Underdog lines appear on the board with their own platform chip wherever the feed carries the sport.
- The sides Underdog sells come from the app's own option list, so a one sided higher only offer is never shown with a lower.
- Where Underdog publishes a price on a side, that price is treated as published: it drives the break-even and the expected net return shown on the row.
- Where a one sided offer carries a stated payout multiplier, the multiplier is carried through to the comparison instead of a price.
Terms that change how a prop reads
- A player who does not appear voids that leg, so probabilities are conditional on the leg being decided.
- A two sided offer is a standard offer whatever its price, and the product will not read a boosted or reduced payout into it from the odds alone.
- An entry reduced to a single player refunds rather than paying a reduced table, which is not how every app handles it.
- Underdog's own scoring chart is what fantasy score markets settle on, and it differs from other apps.
What Slateline cannot do
- In several sports Underdog reaches the product only through an aggregator, which carries the over side and not a directly published under price.
- Slateline cannot see your account, your entries or your balance, and it never submits anything.
Platform rules change. Check the app's own rules page before relying on anything here.
