How the Underdog Promo Code TOPACTION Works for College Basketball Today
When you sign up with the Underdog promo code TOPACTION, play $5+ and get $75 in fantasy bonus entries to utilize for any sport, including college basketball today. Let's break down how entries work at Underdog.
There are two different entry formats to choose from: Standard and Flex. A Standard entry requires all of your picks to win to receive a payout, while a Flex entry requires you to win all picks or lose just one. The key difference is that a Flex entry provides a much smaller payout when you win all of your picks, while a Standard entry rewards you much more for the risk you take.
Here is an example of a $5 Standard entry I created that contains NCAAB picks, which has a 3x payout multiplier:
- Jeremy Fears Jr. (Michigan State) Higher Than 17.5 Points
- John Blackwell (Wisconsin) Lower Than 23.5 Pts + Rebs + Asts
- Robert Hinton (Harvard) Higher Than 17.5 Points
Here is what I receive based on the outcome of the entry:
- If all of my picks win, I receive a $15 total payout ($32.50 profit + $5 entry back) and $75 in bonus entries.
- If one or more of my picks lose, I receive $75 in bonus entries.
