Underdog Flex: How to Optimize Flexed Entries at Underdog Fantasy

by Chris Altman (Caltman) Last Updated 2025-04-07T16:41:25

When making your picks at Underdog Fantasy, you might notice the option to “Flex” your entry. But what exactly does this feature entail?

I’m here to share everything you need to know about flexing 💪 at Underdog. You’ll learn how this feature can increase your chances of winning, albeit at lower payouts. I also go over how flexed entries differ from standard entries and tips for when/how to use the Underdog Flex feature.

What Is Underdog Flex?

Underdog Flex is a feature exclusive to Underdog Fantasy’s pick’em entries. It makes it easier to win an entry but decreases multipliers, meaning you’ll get lower payouts if you win.

Its lower-risk, lower-reward payout structure is perfect for beginners wanting some cushion on their entries and experts desiring to take a risk on underdogs.

Remember, the “Flex” is just short for “flexible.” Flexed entries have more wiggle room, as you can get a payout even if one or more of your picks are incorrect.

If you still need to sign up for this DFS app, be sure to claim the Underdog signup bonus.

How Flex at Underdog Works

Flexing at Underdog couldn’t be easier. Just make your picks like normal in the app, they go to the entry tab.

Under Expected payout, choose the Flex option and see what the multipliers will be. Then, just submit your entry as usual.

As you can see from the screenshot, I’m in a state where Champions is legal. Luckily, Flex is also available in this format.

Flexed Entry Payout Structure

The multipliers (and therefore payouts) you get from Flexed entries depend on how many picks are in the entry and how many picks you get wrong.

Note that for all of the scenarios below, your entry must have at least three picks before you can Flex it. You may not flex a 2-pick entry.

Flexed Entry Payouts With a Tie/Void

A Flex entry with one tie/void will get the payout of the next closest entry:

So, if you flex an 8-pick entry that ends up having one tie/void, you’ll get the 40x payout that corresponds with the 7-pick entry multiplier.

Flexed Entry Payouts With 1 Loss

Here are the multipliers for Flexed entries that end up with 1 loss. The more picks your entry, the higher the payout will be:

Flexed Entry Payouts With 2 Losses

If you want to give yourself the leeway of two losses, your entry must contain at least six picks. The payouts for flexed entries with two losses (double-flexed) are as follows:

Pros and Cons of Underdog Flex

Here are some of the pros and cons of flexing entries at Underdog Fantasy:

Pros

A few reasons that I personally love flexing include:

Cons

As much as I like flexing at Underdog, the feature comes with its downsides:

Hindsight is 20/20, sure, but there’s nothing worse than all of your picks being correct when you flexed. Because even though they’re all right, you’ll get the payout at Flexed rates.

Underdog Fantasy Standard Entry vs. Flex

The difference between a Flex and standard entry is simple—standard entries are traditional pick’em contests that require you to get all picks correct. If you opt to flex your entry, you can get up to two picks wrong and still win.

Of course, the increased flexibility of a Flexed entry comes at a cost. You’ll have to settle for lower payouts, while the accuracy that a standard entry requires rewards you with higher multipliers.

How to Maximize Underdog Flex

Want to get the most out of flexing entries at Underdog? Here’s how to capitalize on the feature:

Do Your Research

We know that many of you play based on instinct, but if you want to get the most out of Flex, you should consider doing some research.

One of the best options is our daily Underdog Fantasy picks tool. It provides the latest insights into top picks for NBA, NFL, MLB, NHL, and other sports so you can find the best edge.

Personally, I use this tool for Underdog and other apps like PrizePicks to find strong picks. If any of my entries have picks that are riskier, that’s when it’s time to flex.

Check Community Forums

While it might not be the most scientific method for building optimal Flexed lineups, community forums can offer interesting insights. People might find edges at Underdog that you initially overlooked or have unique perspectives on which picks to take on a Flexed entry.

You can incorporate opinions from average users and experienced daily fantasy players to make balanced decisions.

Diversify Picks

While Flexed entries help you mitigate riskier picks, you should also have some solid selections in your lineups. This way, the Flexed part can focus on saving you if your riskier picks go haywire.

Other DFS apps don’t have a feature like Flex—see our review of Underdog vs. PrizePicks for more comparisons.
