Super Bowl weekend always brings out the best promotions, and Underdog, the social sportsbook, is leaning all the way in with The Big Reveal, a new promotion designed to stack value the more you play. With the biggest game of the year finally here, this promotion is all about momentum: unlocking rewards, chaining boosts, and turning entries into even bigger payouts.
At the same time, Underdog is giving UFC fans something extra this weekend—but make no mistake: the Super Bowl is the main event.
Super Bowl entries with escalating boosts
Starting tomorrow, Underdog’s Super Bowl promotion puts players in control right from the start. You begin by choosing your player, then revealing what you’ve unlocked. That reveal could land you a Gimme Pick, instantly lowering the difficulty of your entry, followed by a Boost Builder tied directly to the big game.
The real hook comes after that.
Once the Super Bowl promo is live, every boosted entry unlocks an even bigger boost on the next one. Keep playing, and those boosts climb up to 60%. The concept is simple: the more you stay involved, the more Underdog rewards you.
It’s a smart structure for Super Bowl weekend, especially for players who like building multiple entries across props, stat lines, and game scripts. Instead of a one-and-done bonus, The Big Reveal encourages players to keep pushing forward and stacking value as the weekend progresses.
With massive interest around Super Bowl props every year, this promotion fits naturally into how players already approach the biggest betting weekend on the calendar.

UFC 325: Extra boosts for MMA fans
While the Super Bowl promo takes the spotlight, Underdog isn’t ignoring fight fans.
For UFC 325 this weekend, players on the social sportsbook can take advantage of a 50% boost, along with a Gimme Pick to make entering contests even easier. It’s a strong add-on for anyone planning to mix some MMA action into their weekend slate.
The UFC offer works well as a complementary promotion, especially for players bouncing between sports or looking to diversify entries while still chasing boosted payouts.
The Big Game + UFC 325 promo reveal
Between The Big Reveal Super Bowl promotion and the UFC 325 boosts, Underdog is aiming to make this one of its most player-friendly weekends of the year. Bigger boosts, easier entries, and rewards that build on themselves make this a promotion slate worth paying attention to as the Super Bowl finally arrives—on a social sportsbook built for players who love to compete, share, and win together.
