Nevada-only since its 2024 exit from eight states - and its Vegas operations are transitioning to Caesars

Context for United States: The United States regulates online gambling state by state, not nationally, so an offer on this page is only claimable if you are physically located in a state where that operator holds a licence - most US states license no online casino or poker at all. Check the state, not the country. The Multi-State Internet Gaming Agreement lets state-regulated poker operators pool players across state lines; as of April 2026 its members are Nevada, New Jersey, Delaware, Michigan and Pennsylvania. Nevada also requires an online operator to partner with an in-state casino, keeping its poker market small. SWEEPSTAKES CASINOS ARE A SEPARATE, RAPIDLY CLOSING CATEGORY: dual-currency sites (Gold Coins to play, Sweeps Coins redeemable for cash) are being banned outright, not regulated, in a growing list of states including Montana, Connecticut, New Jersey, New York, California, Nevada, Maine, Indiana and Oklahoma. Sources disagree on the exact total, so check your own state rather than any single figure - and note these laws can reach payment processors and affiliates too, not just the operator.

Pros
- A real, sizeable first-bet match up to $250
- Genuine state gaming licences
Cons
- Minimum odds of -200 required for the qualifying bet
- Deposit and first bet must be placed the same day
- Nevada only - shut down in eight other states (AZ, CO, IA, MD, NJ, OH, TN, VA) in July 2024
- Operations mid-transition to Caesars Entertainment, pending Nevada Gaming Commission approval
- Only 12 sports covered - fewer than most major US sportsbooks
- Some users report withdrawal difficulties and reduced limits after winning
Our verdict
The most important correction here is geography. We had described SuperBook as available in multiple licensed US states. It is not: SuperBook Sports shut down mobile sports betting in Arizona, Colorado, Iowa, Maryland, New Jersey, Ohio, Tennessee and Virginia in July 2024, and now operates only in Nevada, through Westgate Las Vegas Resort & Casino and its Westgate SuperBook Mobile app. A more recent change is worth knowing even if you are in Nevada. On 21 April 2026, Caesars Entertainment announced an agreement with Westgate Las Vegas to take over the SuperBook's race and sportsbook operations and technology - rebranding it 'Westgate SuperBook, powered by Caesars Sportsbook' - pending Nevada Gaming Commission approval. Westgate keeps ownership of the physical property; Caesars takes the operational and technology side. That is not a closure, but it means the app and platform you sign up for may be mid-transition to Caesars' own sportsbook technology. On day-to-day use, independent reviews describe a comparatively narrow offering - 12 sports, fewer than most major competitors, no decimal-odds option - and some users report withdrawal difficulties and reduced betting limits after winning. Others describe the odds as reliable. We report both rather than only the complaints.
How we rated it
Bonuses & value (18%)7.5
A real, sizeable first-bet match up to $250. Only claimable in Nevada, where the brand now operates.
Trust & licensing (27%)7.5
A real positive: genuine state gaming licences across multiple US states. Nevada gaming licensing is solid, but the brand's national footprint collapsed in 2024 and its Las Vegas operations are mid-transition to Caesars, pending Nevada Gaming Commission approval.
Customer support (18%)7
No major documented complaint pattern found. Independent user reviews report withdrawal difficulties and reduced betting limits after winning, alongside some positive comments on odds reliability.
Sportsbook (36%)6.5
Cut from 7.5. We were describing this as available in multiple licensed US states; it withdrew from eight (Arizona, Colorado, Iowa, Maryland, New Jersey, Ohio, Tennessee, Virginia) in July 2024 and now operates only in Nevada, through Westgate Las Vegas. Coverage also only spans 12 sports, fewer than most major competitors, and a Caesars operational takeover was announced in April 2026, pending regulatory approval - real change a reader should know about before signing up.

How we verified this
One thing we could not establish: who owns and operates this brand. The rest of this review is sourced, but an operator we cannot name is one you cannot hold to account.
State availability checked against dedicated closure coverage (Legal Sports Report, SportsHandle) rather than assumed current from the operator's own marketing. The pending Caesars operational takeover is reported with its regulatory-approval caveat rather than as a done deal.

About SuperBook
SuperBook is the sportsbook of Westgate Las Vegas Resort & Casino, and it is Nevada-only: it shut down mobile sports betting in eight other states - Arizona, Colorado, Iowa, Maryland, New Jersey, Ohio, Tennessee and Virginia - in July 2024. We had it listed as available in multiple US states, which is no longer accurate. A further change is in progress: on 21 April 2026 Caesars Entertainment agreed to take over the Westgate SuperBook's race and sportsbook operations and technology, pending Nevada Gaming Commission approval, while Westgate keeps ownership of the property. Independent user reviews cite withdrawal difficulties and reduced betting limits after wins, alongside a comparatively narrow 12-sport offering.
