Who Should Make Use of This Article?

This article is ideal for any first-time gamblers or experienced gamblers that are looking to learn more about what No.1 bookies have the best horse racing betting offers in the USA. It’s also useful for those looking at how to bet horses successfully, understanding horse racing accumulators and horse racing betting odds

In this article, we will dissect what U.S. horse racing betting promotions are out there, the best horse betting strategies, and overall reviews of horse racing bookmakers in the US.

Top 5 Steps for a Secure & Fair Gambling Experience

What are the main things that a gambling site needs to adhere to for us to be sure that it’s a safe and secure gambling experience other than it offering the best value U.S. horse racing betting promotions?

It’s essential to understand the critical aspects of gambling securely and fairly online, and not being caught out by a scam.

We’ve done our research and have narrowed it down to the following key elements:

Industry Reputation

It’s a good idea to check out the reputation of your chosen gambling site on forums and other online casino reviews for the USA. Often if it’s a large reputable brand, you will find some extremely insightful knowledge from previous and existing users. If the reputation is poor, it doesn’t matter how good the U.S. horse racing betting promotions are.

User Experience

The user experience should be one of the highest quality from start to finish. We understand that having to use a clunky and poorly designed website is the opposite of what you want when trusting your money to an online gambling operator. We check to make sure that every care has been taken, so that you can get the most enjoyable experience out of any of the providers we recommend.

Licensing and Legislation

Each of the operators that we suggest have been fully licensed. If they don’t adhere to these guidelines, then they don’t make the cut, regardless of how good the U.S. horse racing betting promotions on offer are.

Security and Support

Any betting site you choose to use must have a secure transactional system in place for document storage, betting history, personal history, and payments.

It’s also vital that each site provides a reliable customer support process; this includes quick response times, being efficient with issues and queries, and also ensuring that they are licensed and regulated. Without this, any U.S. horse racing betting promotions provided are best avoided.

Odds and Pricing

For some users, the best sports betting odds and prices offered by a No.1 bookie is the only reason to choose one site over another. The gambling market is extremely competitive, and the change in odds of one event across various accounts can be significant. Therefore, it’s handy to research more than one site, to ensure that you’re getting the best value for each bet that you place.

Editor’s Recommendation

Our experts have conducted extensive research into numerous different operators, to find one that stood out to us as the online casino with the best horse racing betting offers in the USA.

While a lot of betting sites use similar large software suppliers, some have their software created for them, while others employ less well-known developers. It was essential to test them all, to see which casino sites offer the best range of horse racing options to choose from. After our research into the various U.S. horse racing betting promotions, we determined that this is 888Casino.

In-play betting

So what makes the promotions the best horse racing betting offers in the USAOn 888Casino, there’s a wide range of in play betting on horse racing. Odds automatically refresh as the action unfolds, giving you real-time competitive odds for you to deliberate and bet on, keeping the action fun and exciting.

Game software

888Casino hosts its own software, which is developed by Dragonfish. Dragonfish is the official development arm of the 888 Group.

As it is software that the company owns, it allows them to put on horse racing events that are found at very few other casinos. As well as its unique events, it also boasts a host of famous races and provides a wide-ranging game portfolio for its users; all in all, there are plenty of options to choose from. This is a massive factor as to how they provide the best horse racing betting offers in the USA.

Live streaming

888Casino is also one gambling site that offers a range of live streaming options on a lot of horse racing. This provides an added element of fun and excitement, as you can watch the action unfold as you place your wagers.

How Do We Do Our Testing?

Our experts have sifted through a range of different sites, testing out everything from their operating systems across all devices, what games are on offer, and what the in-play betting options are to find the best horse racing betting offers in the USA. Nine key criteria needed to be assessed to meet our standards:

  1. Range of betting options – Is the software advanced enough to allow for a range of different betting options?
  2. Customer Support – Are there fast and supportive customer care systems in place?
  3. Simplicity – are the payouts simple and easy to understand?
  4. Popular games – Does the operator provide popular horse races to bet on?
  5. Running Speed – How quick is the software on-site?
  6. In-play options – Is the operator advanced enough to allow for other in-play side bets?
  7. Payment System – What are the online gambling withdrawal options? Does the sportsbook have a cash out option?
  8. Usability – Are the horse racing events functionally smooth and fun to use?
  9. U.S. gambling apps – Do the events also run smoothly on the Best Betting Apps?

Finding The Right Operator for You

Looking for a good operator or not 100% satisfied with your current operator? We have the perfect tool for you to find the online casino with the top U.S. Horse Racing betting promotions and best horse racing betting offers in the USA. Check it out at the top of this article!

This Is How You Find YOUR Perfect Gambling Site!

Want to do your research and find the online casino with the best U.S. horse racing betting promotions that suit you perfectly? If so, you need to keep certain key criteria in mind. Ask yourself the following questions before embarking on your search for the perfect operator for you. These pointers will also help when looking for other sports, such as MLB betting sites.

Are you looking for horse racing variety?

Some sites offer wide horse betting variety, whereas others stick to the more traditional choices. This often depends on what software it is running and this is something that’s helpful to know when choosing the best U.S. horse racing betting promotions.

Are you new to gambling?

Have you gambled online before? If not, it would be worth doing some research into which site to choose. Most sites offer a wide range of lucrative horse racing betting offers in the USA for you to pick from and some software is easier to use than others.

Do you expect to do a lot of live in-play betting?

One of the main benefits of gambling online is the option of constantly updated in-play betting. If this is your cup of tea, then it’s worth noting that not all sites offer this feature, so it’s important that you do your research into what software the site is running before you invest.

Will you be using your PC, Tablet, or Mobile?

Online gambling is accessible in a wide range of formats, from PC to mobile. If you’re an avid phone-gambler, it’s worth checking out if your chosen site has an app, and how user-friendly its software is.

Which Gambling Site Do We Use?

Our experts like to see several criteria ticked off when they are choosing the online casino with the top U.S. horse racing betting promotions.

Software on online gambling sites need to be set up so that the site is simple to navigate, betting odds are easily laid out, and it should be easy to find games you are looking for; in this case, this includes the horse races you’re looking to gamble on.

When we choose a site as our top pick, one of the first things we check is what the company’s app is like, if they have one that is. More and more users are playing on the go, or just preferring to play on their mobile, so it’s also important that the best horse racing betting offers in the USA are available on mobile as well.

Another area that impacts our experts’ choice of operator is the various in-play betting options, which isn’t an option all sites offer. Some high profile horse races provide great in-play action, and your casino of choice should offer odds on the action.

We also feel that it’s vitally important that the customer service is top quality. There needs to be a variety of help and support options available on the betting website. For example, a ‘contact us’ page, FAQ page, and some general helpful tips should appear throughout the website. These often cover a lot of the answers that users are looking for. However, there should be other options available for further help, should it be needed.

Final Conclusion

If you’re looking to find the online casino for the top U.S. horse racing betting promotions, then ensure that the site you choose fits the criteria mentioned above, most importantly:

  • Horse betting signup bonus – What is the site’s horse racing betting offer in the USA?
  • Popular games – Does the operator provide popular horse races to bet on?
  • In-play betting – Some high profile horse races provide great in-play action, and your casino of choice should offer odds on the action. Now you have everything you need to find the best horse racing betting offers in the USA.
