The verdict
If you want to play daily fantasy, Underdog is one of the two places to start, and the first place if you care about Best Ball. The draft room is the best in the business, entry is low, and the app is quick and clean. The catch is the one that applies to all DFS: it is a game of skill, not a sportsbook, so what you can play depends on your state, and Pick'em in particular is restricted in more places than the draft contests.
What you can play
Season-long drafts with no in-season management; your best lineup is scored automatically each week. Underdog is the market leader here.
Choose whether players go over or under a projected stat line and combine picks for a multiplier. The player-prop-style format; availability is more state-restricted.
Fast-draft single-day and traditional snake-draft contests across the major sports, available in every state where Underdog operates.
