Playing on Underdog and their picks platform has two standard ways to create an entry, along with additional promotions that are a little more unique.
As far as the two entires go, you can either enter a standard contest with 2+ picks for a shot at the largest payout, but keep in mind that all legs must hit. Then, the other option is to flex an entry, which will still result in some winnings of only one leg is incorrect. That said, if you get every single pick correct it will be a lower payout than a standard contest.
The additional promotions on Underdog include ladders, streaks, and injury protection via the rescues promotion. There are also NBA and NFL packs, which are pre-populated entries to give you a head start on how to play the slate.
