Real Money Online Casinos DE

Delaware is a trailblazing state: it was the first US state to sign the constitution, the first to legalize online casinos in 2012, with the passing of the Delaware Gaming Competitiveness Act, and the first state to create a multi-state poker network!

For five years (until 2017, when the PA market opened), Delaware was one of only two states offering legal and regulated online gambling to players in the USA. But how do things stand today, and what are the best online casinos in Delaware? Sit tight and get ready to roll as we take you on a whirlwind tour around Delaware's online casinos!

Who Can Gamble in Delaware?

Anyone who is over the age of 21 and physically present in the state can gamble online at Delaware casinos. This includes visitors and residents, but players need a US social security number to complete a casino's registration form!

Legality of Gambling in Delaware

Online gambling became legal in Delaware in 2012 with the passing of The Delaware Gaming Competitiveness Act. This act allowed for real-money bets to be placed online at casinos, which secured licensing from the DE State Lottery and Delaware Division of Gaming Enforcement (DGE).

Like elsewhere in the USA, each online casino in Delaware must form a licensing partnership with a land-based establishment, so those looking for legal, regulated, and safe online gambling can choose between Bally Casino Delaware Park and Harrington Raceway.

Gambling Market Size in Delaware

Delaware is somewhat of a stagnant market. Not much has changed since online gaming became legal in 2012: the same three online casinos are operating and offering the same product as when they first launched in 2012. 

No new openings have occurred due to simple numbers: Delaware has three established racinos (racetracks and casinos), each with an online platform. 

But why has a lack of innovation and development at the sites already established in the Delaware market? It's down to the exceptionally high tax rates and “revenue sharing” scheme.

What is “Revenue Sharing”

Revenue sharing in Delaware means that the first $3.75 million of all online gaming revenue goes straight to the state, with no profits going to the operator. After this, the state charges 62.5% taxes on all income. No other US state has a benchmark on profit or taxation system like the Delaware casino revenue sharing system. 

This system has proved a deterrent to software studios and casinos from applying for licensing and investing in Delaware, even though DE licensing is highly regarded.

What is the Delaware Market Worth?

According to the revenue-sharing model and the official figures shown below, Delaware only became a profitable market for operators in 2020.

Best Online Casino Bonuses in Delaware

The best casino bonuses can always be found on gambling platforms. Online sites have much lower operating costs than land-based establishments, which means they can offer more rewards to players. Plus, they are competing more fiercely for players (who can select from any number of sites without being constricted by location), so it is pragmatic for gambling sites to be generous with bonuses.  

Players can earn the following types of Delaware casino bonuses while playing online:

  • welcome deals that double your money, 
  • free spins to keep you winning, 
  • loyalty points that can be collected and exchanged, 
  • tournaments, 
  • daily deals, 
  • login treats and much more.

How Do Casino Bonuses Work in Delaware?

Each of Delaware's gambling sites uses the same platform and software, so there is minimal divergence between the online casinos in Delaware real money gameplay. To make things even more confusing, each online casino in DE offers the same welcome deal, a 100% matched bonus.

Online Casinos in Delaware: No Deposit Bonuses

Online casinos in Delaware with no deposit bonuses are a great starting point for new players, as you can play for free, test the site, and win real money prizes. However, Delaware's three online casinos don't offer a no deposit bonus.

Delaware Sports Betting

Sports Betting has been thriving in Delaware since before the repeal of PASPA. Interestingly, DE was one of only four states initially exempt from this federal law, and as such, the state lottery has always offered NFL parlay wagers. Delaware casinos also offer in-person sports betting alongside casino gambling.

Since 2024, bettors can also place online sports bets at any of Delaware's online casinos. Each site has a fantastic selection of sports (over 28) and hundreds of daily markets. You'll find the most popular sports betting leagues and events alongside more niche options, like floorball!

Casino Games Delaware

There are two licensed and regulated software providers in DE: IGT and Light & Wonder (previously Scientific Games), which includes Barcrest, Bally Technologies, WMS, and NYX.

play online slots in delaware

Play Online Slots in Delaware

Slots are the most popular real money casino game, and online casinos in Delaware offer an excellent selection of top-tier titles. IGT is an iGaming giant and provides many classic titles, like Da Vinci Diamonds and Cleopatra. Mix these top-class titles with the very popular and more modern Light & Wonder titles, and players have access to an all-star selection of slots. This makes for an excellent gaming experience covering the classics and more cutting-edge titles.

go classic with table and card games

Go Classic with Table and Card Games

If you're looking to play online table and card games with real money online casinos in Delaware, you can choose between seven variants of Blackjack and American Roulette. Due to the limited supply, we recommend you head to one of Delaware's land-based casinos for a more comprehensive selection or try playing for free at a sweepstakes casino site.

fantasy sports

Fantasy Sports

Fantasy Sports have been legal in DE since 2017 but are not offered at any online casino in Delaware. Instead, fantasy and virtual sports are provided by specialized and independent sites, including DraftKings and FanDuel (Fantasy Sports is the only case when you can use a gambling site not registered in DE).

Sweepstakes vs. Real Money Online Casinos in DE

We touched on Sweepstakes earlier, but this type of game site deserves more explanation. Sweepstakes casinos, like Wow Vegas and Stake.US, offer an alternative gaming option in Delaware. Many sweepstakes sites provide more games than the real money DE casinos on this page but do not offer traditional payouts. While you can win prizes, it's not based on the game outcome as with conventional gambling.

The idea behind US sweepstakes casinos is that players use a virtual currency to play. These coins are given as bonuses and, under certain conditions, can be exchanged for prizes.

If you want to game on the go in Delaware, you can pick from any of the three operators in the state. Each has a downloadable mobile app for Android and iOS/iPhone users or can be used as a live mobile site (use your cell phone browser to load up the site and play). 

The apps can be downloaded directly from the casino using your phone or from the respective app store. Setting up the app takes just a few minutes, and then you can play top-of-the-range casino games from anywhere.

DE Casino Payment Methods

Delaware online casinos accept Visa, Mastercard, ACH transfers, Online Banking, Play+, PayPal, and Venmo for both deposits and withdrawals. All the named payment methods are safe and secure and offer excellent service. If you're looking for the fastest and most user-friendly options, use Play+, PayPal, or Venmo (these offer 24-hour cash outs at online casinos in Delaware).

Safety, Licensing, and Responsible Gambling

When playing at a DE online casino with real money, ensuring that your cash and data are securely processed and stored is paramount. Like every gambling jurisdiction in the US, the Diamond State's regulations are strict about compliance, security, and player safety. This ensures that only the best operators and software are allowed to operate. Here are some essential elements of online casino safety in DE.

✅ Casino and Game Audits 

Operators must submit third-party software reports and casino audits to the Delaware Lottery. These reports must be kept for a minimum of five years. Third-party testing ensures that games are fair, payout, and operate randomly using an RNG (random number generator). 

✅ Player Protection and Responsible Gambling

Each online operator in DE is charged with being responsible for how it offers and markets its product. Casinos must support vulnerable players, offer account tools like time limits, deposit limits, and self-exclusion, as well as inform players of the potential dangers of addictive gambling. 

Site Encryption

Every site we recommend at Casino Cabbie uses top-of-the-range SSL encryption. When you use the platform, your connection to the casino is secure and encrypted- only to be decrypted by the operator’s server.  

Land-Based Casinos Delaware: Meet the Racinos

Located throughout The Diamond State, the racinos of Delaware are each owned by a different operator. While they may share a single online platform, the land-based racinos are each unique. The two most popular racinos in terms of gaming revenue are Dover Downs and Delaware Park.

Bally's Dover (formerly Dover Downs)

Twin River Worldwide Holdings owns Bally's Dover Casino Resort. The racetrack comprises a 625-mile horse racing track, surrounded by the 1-mile motor racing speedway and a 500-room hotel. The on-site casino also hosts over 2,700 slot machines and 40 table games.

Located off the North Dupont Highway, Dover Downs Racetrack was constructed in 1966, specializing in motor and horse racing. The first race at Dover Downs took place in 1969, and by 1995, Dover Downs launched their race-side casino; then, in 2013, their online site and mobile app- Dover Downs Casino. In 2024, the online casino and land-based establishment was rebranded to Bally Casino.

Harrington Raceway & Casino

Harrington Raceway & Casino is a harness racetrack and casino located south of Harrington, Delaware. It’s the smallest of the three establishments in the state, with 1,800 slot machines on-site. Harrington Raceway opened in 1946 and then expanded in 1996 to offer games. In 2013, they opened their online site and mobile casino app.

Delaware Park

Located just outside Wilmington, Delaware Park is a 1-mile oval horse racing track, golf course, and casino close to the PA border. As the oldest racing site in Delaware, this track was constructed in 1937 and is one of the top-grossing gambling locations in DE, seeing up to 8,000 patrons per day. The land-based casino has 2,500+ slots on-site, while the golf course has 18 holes, and the race track is the only one in the state to host thoroughbred horseracing from May through October.
