How to Sign Up For Underdog Fantasy
What is Underdog Fantasy?
Underdog Fantasy is one of the Daily Fantasy Sports sites that is legal in many states where sportsbooks like Caesars, DraftKings, and FanDuel are not. Best of all, with promo code ‘ODDSJAM’ you can get a first deposit match up to $100. That’s a free $100 to help get your bankroll off to a good start.
It’s a little different from classic sportsbooks in that each Pick’Em entry is made up of a combination of player props where you select if the player will go higher or lower than the line.
For example, a prop to include in an entry may be if Aaron Judge will go higher or lower than 1.5 total bases in a given game.

How does Underdog Work?
Underdog has several different payout structures depending on how many props are included in your entry. You may also choose whether or not to insure your entry, which means less payout if everything wins but a smaller payout if just one leg loses. Here’s a breakdown of the payout structures:
Non-Insured
| Number of Props in Entry | Non-Insured |
| 2 | 3x ($10 stake pays $30) |
| 3 | 6x ($10 stake pays $60) |
| 4 | 10x ($10 stake pays $100) |
| 5 | 20x ($10 stake pays $200) |
Insured
| Number of Props in Entry | All Win | Exactly One Loses |
| 3 | 3x ($10 stake pays $30) | 1x ($10 stake pays $10) |
| 4 | 6x ($10 stake pays $60) | 1.5x ($10 stake pays $15) |
| 5 | 10x ($10 stake pays $100) | 2.5x ($10 stake pays $25) |
Note that the payout includes your stake. So a 10x payout with $10 paying out $100 means $90 of profit.
How to Make Money on Underdog
Simply put, to profit long-term on Underdog you need to be winning individual props at a higher rate than the implied odds.
Essentially, a 3x payout is equivalent to +200 odds. So you need to find three props to parlay together that have a true value lower than +200 odds. That number is -122. To profit long-term, your Underdog props for two-leg entries with 3x payouts MUST have a higher probability of hitting than -122.
Here’s a full breakdown for every entry type:
| Entry Type | Implied Odds to Beat |
| Two-leg non-insured | -136 |
| Three-leg non-insured | -137 |
| Three-leg insured | -122 |
| Four-leg non-insured | -123 |
| Four-leg insured | -128 |
| Five-leg non-insured | -122 |
| Five-leg insured | -120 |
As you can see, the best entry type to win in the long run is five-leg insured. At -120 odds, we’re able to find a lot more profitable props than if we have to beat -137.
I’ve made a ton of money off Underdog, so be sure to watch this video breaking down how.
The reason I’m able to find so many profitable bets is because of the OddsJam Fantasy Optimizer. The screen not only shows Underdog, but can also be filtered to show profitable bets on PrizePicks, No House Advantage, ParlayPlay, Jock MKT, and Thrive.
If you are new to Underdog Fantasy (a PrizePicks competitor), then I recommend reading this betting strategy article. Almost always, it is mathematically optimal to place “three-pick” and “five-pick” entries on Underdog Fantasy. I rarely give out plays that do not have three or five picks. Two-pick entries are a surefire way to lose money on this DFS platform.
