When putting together your slips, Underdog gives you a couple of strategic options for how to play your picks. You can choose a Standard entry, which requires 2+ picks and triggers the largest potential payout. However, keep in mind that all legs must hit perfectly to cash a standard slip. The other option is to Flex an entry, which requires 3+ picks. Flexing your slip offers a bit of a safety net, meaning you can still receive some winnings even if a leg is incorrect. Decide which strategy fits your analytical read on the game and enjoy the action!
