FanDuel Sportsbook's "Dog of the Day" promotion gives you the chance to win a share of $1 million in bonus bets simply by betting on the lowest-seeded team to win on March 21, 2025. Yesterday was #12 McNeese who Dimers predicted with a 22% probability with a shocking win over #5 Clemson.
Plus, new users who haven't yet signed up for FanDuel can earn a $200 bonus if they place and win their first $5 bet at the sportsbook - claim via the offer below!
How the "Dog of the Day" Promo Works
Claim Your Token – Log in to your FanDuel Sportsbook account and claim your "Dog of the Day" Jackpot Token from the promotions page.
Place a Moneyline Bet – Use your token on a straight moneyline wager for any March 21st NCAA Tournament game.
Win and Share $1 Million – If your chosen team is the lowest-seeded team to win that day, you’ll split $1 million in bonus bets with all other participants who wagered on the same team.
- Key Terms and Conditions
- Minimum wager: $0.09
- Only pre-live, straight moneyline bets qualify
- Bonus bets will be credited within 72 hours
- Tokens must be used before 11:59 PM ET on March 21, 2025
- State restrictions apply; users in certain states may need to bet on the next-lowest seed
Example Payout
If #15 Wofford is the lowest-seeded team to win and 10,000 bettors used their token on them, each participant would receive $100 in bonus bets ($1,000,000 / 10,000 = $100 per person). If multiple teams tie for the lowest-seeded win, the prize pool will be evenly distributed among all qualifying participants.
For users who are prohibited from betting on in-state teams, if a Connecticut team like #13 Yale wins their game as the lowest seed of the day, then the next lowest team who wins (#10 Arkansas for example), will qualify in that state.
Best College Basketball Tournament Upset Picks Today - March 21, 2025
Below you'll find Dimers' win probabilities for college basketball tournament teams seeded between #10 and #13. To see our upset predictions for all teams, including the 14-16 seeds, use our Dimers Pro college basketball picks.
| TEAM | OPPONENT | UPSET PROBABILITY |
|---|---|---|
| #11 North Carolina | #6 Ole Miss | 57% |
| #12 Colorado State | #5 Memphis | 54% |
| #11 Xavier | #6 Illinois | 38% |
| #10 New Mexico | #7 Marquette | 38% |
| #10 Vanderbilt | #7 Saint Mary's | 33% |
| #12 Liberty | #5 Oregon | 23% |
| #13 Grand Canyon | #4 Maryland | 17% |
| #13 Akron | #4 Arizona | 10% |
Based on our model's predictions, both North Carolina and Colorado State are strong options given their mid-low seed and over 50% win probability. However, for those looking to take a longshot on a less popular pick, #12 Liberty and their excellent defense looks like a solid play.
