Understanding Your Entry Options
When building a lineup for the Spurs vs. Pistons game, Underdog offers two distinct ways to play. It does stand to reason that understanding the risk profile between a Standard entry and a Flex entry is key to managing your strategy:
- Standard Entry: This format requires you to make at least two picks (for example, combining props for Victor Wembanyama and Cade Cunningham). To win a Standard entry, all legs must hit. This option carries higher risk but triggers the largest payouts—ideal for those confident in their specific reads.
- Flex Entry: This option is available when you make an entry with three or more picks. It acts as a safety net, allowing you to receive some winnings even if one of your predictions is incorrect. While the maximum payout is lower than a Standard entry, the added insurance is popular for building longer rosters and mitigating variance.
Note: This offer is valid for new users only. Players must meet age and region requirements to participate.
