This brand is not licensed in the markets we cover (or only in part of them), so it has no Wayfinder Score. If you play there, you do not get the protections a local licence brings: limits, self-exclusion and a regulator to complain to.

How it works
Underdog launched in 2020 and popularised best ball, a draft-only format with no weekly line-up changes. Its pick'em game asks users to predict whether athletes will go over or under statistical lines, and multiplies the entry if every pick is right.
Drafts and contests are played for real-money entry fees.
Where it stands
Fantasy contests are legal in most US states under their own rules, but several regulators have ruled that pick'em against the house is sports betting. Underdog has changed or withdrawn that product in some states as a result. It holds no licence in the other markets we cover.

What to know
Multi-pick entries are attractive because of the multiplier and rarely come in. Fantasy apps also lack some of the safeguards required of licensed sportsbooks.
