How to Use Underdog Fantasy Promo Code TOPACTION on NCAAF Lineup
With the Underdog Fantasy promo code TOPACTION, you can claim a $100 welcome bonus for today’s college football slate. Here’s what Nick Goodling has to say about claiming this offer from one of the best DFS apps:
"Claiming the $100 welcome bonus is a great way to jumpstart your first lineups and explore different strategies. It gives you extra flexibility to experiment and maximize your DFS experience from day one."
Once you complete the sign-up process, it’s time to create your first lineup. Simply select "Higher" or "Lower" on a player projection to add a pick to your lineup. If your lineup has three or more picks, you must choose between the Standard and Flex lineup.
With the Standard entry, you get the maximum payout, but you must win every pick. The Flex lineup offers a smaller payout if your lineup is perfect, but you can still profit or get your stake back even with one losing pick.
