Select your Thursday Night Football picks with Underdog Fantasy promo code LABSNEWS, then make a Standard or Flex entry today. A Standard entry offers a higher payout multiplier, but you must get all your picks correct to win. Meanwhile, a Flex entry allows you to miss one pick and still win, but it comes with a lower payout multiplier.
With a three-pick Standard entry, the payout multiplier is 6x. If you make a Flex entry instead, the payout multiplier is 3x or 1x. The number of correct picks within the entry determines the payout on a Flex entry.
