Caesars Bets on Flex Parlays and Bet Insurance: A Comprehensive Guide to Modern Sportsbook Features

As the sports betting industry matures, operators are discovering that simply adding more betting markets is no longer enough to keep users engaged. Bettor habits are shifting—players want not only more ways to wager but also more ways to protect their bets when the unpredictable strikes. Dominic Hammond, Senior Vice-President of Sports at Caesars Digital, explains: “For me, content will always be king. We’re constantly adding new markets… and we always perform very well.” Yet Caesars recognizes that market volume alone doesn’t retain customers. In response, the company has rolled out a suite of features designed to reduce bettor fatigue and increase loyalty, with the NFL season as the ultimate proving ground.

This guide breaks down Caesars’ latest innovations—Flex Parlays, Injury Protection, and Squad Builder—and places them in the context of a rapidly evolving competitive landscape, including the rise of prediction markets and rival sportsbooks’ own protective offerings.

Beyond More Markets: Why Bettor Retention Matters

The old playbook of “add more props, offer more same-game parlays” is still important, but Hammond notes that volume is no longer a differentiator. What bettors truly want, beyond the ability to place a bet, is the ability to protect that bet when key players get injured or when a parlay leg fails.

“Losing parlays over and over again isn’t great. You want to give customers a sense of getting a win,” Hammond says. Caesars listened to its customers, who repeatedly asked: “Give me as many options as you can, and give me multiple ways to protect this bet.”

The result is a trio of products that blend risk mitigation with gamification—a strategy that aims to keep users coming back even after a tough loss.

Flex Parlays: A Safety Net for Multi-Leg Wagers

How Flex Parlays Work

Traditional parlays are all-or-nothing: miss one leg and the entire bet is lost. Flex Parlays change that. With an eligible parlay, a bettor can miss one or more legs and still receive a reduced payout, rather than forfeiting the entire stake.

Hammond recalls the universal frustration: “We all remember the time when we missed the parlay by one.” Flex Parlays directly address that pain point, making the betting experience more enjoyable and less punishing.

Why Flex Parlays Matter

Injury Protection: Refunding Wagers When Stars Go Down

What Is Injury Protection?

Caesars expanded its Injury Protection feature to cover a wider range of qualifying bets—including player props—if a key athlete is ruled out early due to injury.

“Injury Protection was a big one… We heard it from our customers,” Hammond says. He adds that the internal team also considers what they themselves would want: “A lot of us are bettors ourselves—what do we want to build? What excites us?”

Why This Matters for Bettors

Gamification: Squad Builder and Free-to-Play Engagement

Beyond cash bets, Caesars introduced Squad Builder, a free-to-play in-app game designed to keep users engaged throughout the week—even when they’re not placing real-money wagers.

How Squad Builder Works

This type of gamification serves multiple purposes: it keeps users opening the app daily, familiarizes them with player props, and encourages eventual real-money betting on similar markets.

Technology Behind the Features

Caesars’ proprietary technology allows it to roll out these complex tools seamlessly. During the summer 2024 tournaments, Caesars offered ten times as many markets as it did for the 2022 Qatar World Cup. The NFL season, however, remains the “ultimate proving ground” for these innovations. “There’s no getting around the NFL being the biggest platform… where we have the biggest reason to shout in the market,” Hammond says.

The Competitive Landscape: Rivals Are Responding

Caesars is not alone in recognizing the need for bet protection. Competitors are quickly launching their own versions:

These moves underscore a broader industry trend: sportsbooks are moving away from pure volume and toward value-added protection that builds customer loyalty.

Prediction Markets: A New Threat

The product push also comes as regulated sportsbooks face new pressure from the rise of prediction markets (such as Kalshi or Polymarket). These platforms allow users to bet on outcomes in a more exchange-like environment, often with lower margins.

Hammond acknowledges the competition: “We know they have a formidable offering, and they are spending a lot of money.” But he distinguishes Caesars’ product: “Fundamentally, we view their product as sports betting… We know we can take parlays in a completely different direction with things like Flex, plus Caesars Rewards and loyalty programs that prediction markets don’t have.”

The combination of Flex Parlays, Injury Protection, and gamification creates a richer ecosystem that prediction markets—which lack loyalty tiers and sweepstakes-style features—cannot easily replicate.

Conclusion: Why the NFL Season Is the Ultimate Test

Caesars is betting that these features will reduce churn and attract new customers as the 2024 NFL season kicks off. The NFL remains the largest single driver of sportsbook engagement in the United States, making it the perfect laboratory for innovations.

As Hammond says, “We are constantly innovating, but there’s no getting around the NFL being the biggest platform.” For bettors, the new tools offer a blend of excitement and safety—allowing them to take risks on parlays and player props without fear of a single unlucky break ruining their entire wager.

In an industry where the line between entertainment and risk is razor-thin, Caesars is trying to tip the scale slightly more toward fun. Whether that will be enough to outpace rivals and prediction markets remains to be seen, but one thing is clear: the era of “more markets” is giving way to the era of “smarter protections.”
