NFL, NBA Ladders on Underdog Fantasy

One of the most fun ways to play on Underdog is to check out the ladders challenge. Essentially, this is a way to call your shot on players you think have potential to go significantly over what their projection is, hence climbing the ladder.

You must choose a minimum of three players, but if you correctly call your shot on all three of them to reach their ceiling outcome, you can 1000x your initial entry amount.

• TNF Ladder Plays: Derrick Henry and Jaylen Waddle are set up for huge games, with Henry on the rushing yards and Waddle with the receiving yards.
• NBA Ladder Plays: In a star-studded matchup between the Warriors and Bucks, both Steph Curry and Giannis Antetokounmpo are projected to go over what their points prop are set at
