Best Slot Sites & Highest RTP Slots FAQs Our experts signed up with each of the legal and licensed online slots sites in the United States to determine which of the best online casinos provide the best slot options for our users.

Caesars Entertainment owns the largest retail casino estate in the USA, including the Harrah’s, Horseshoe, Caesars Palace and Eldorado brands. It purchased a major online gambling company, William Hill, in 2021 for $4 billion and rebranded the site as Caesars Palace Online Casino & Sportsbook, and it is widely considered one of the leading options. It is a user-friendly site, which is perfect for high-stakes players, as there are large upper win limits and the Caesars Rewards program has an excellent VIP tier. New users who use Caesars Palace Online Casino promo code have a choice of three welcome bonuses, including a 100% deposit match up to $2,500 plus 2,500 rewards points if you wager $25 or more. That match is a little different than what players will find at Caesars' version of its online sportsbook. New players who sign up using the Caesars Sportsbook promo code offer will receive a first-bet offer to $1,000. You very first wager will earn cash profit with a win or a single matching bonus bet back in return with a loss.

Tap “Register” or “Join” or something similar and then fill in the registration form with your name, address, date of birth, email address, phone number and last four SSN digits. Choose a password, agree to the terms and complete the form. You may need to verify your email address by clicking a link sent to it. Some sites ask you to verify your phone via SMS too. You may automatically pass KYC checks through the details provided, but the site may ask you to upload supporting documents – such as your driver’s license and a recent bill – to complete the validation and verification process. When your online slot site account has been approved, you can visit the online cashier to make your first deposit. Choose a method, enter your details, type in a deposit amount and confirm.

We delve into several important areas when reviewing the best new slots sites including the speed, accessibility and overall user experience of the site, along with the customer service, payout speeds and security. We focused on the reputation of each brand when hunting out the best site to play online slots with highest RTP in the USA. Our reviewers only analyzed legal desktop and mobile slots sites that hold licenses from agencies such as the New Jersey Division of Gaming Enforcement, the Pennsylvania Gaming Control Board, the Michigan Gaming Control Board, the West Virginia Lottery and the Connecticut Department of Consumer Protection. We sought out reputable sites that have been paying customers out on time ever since they launched, while also offering robust safety measures, committing to responsible gambling and upholding their licensing conditions. The best site for slot games in your state will offer a very broad variety of titles from lots of different software studios, including industry giants such as NetEnt and IGT, and smaller, more boutique suppliers. They include all sorts of Megaways, instant wins and Megaclusters slots, along with progressive jackpots, classic slots, 3D slots and much more. The top slot sites cover dozens of different themes, and they have low, medium and high volatility games, with upper and lower betting limits to suit all players. Each online slot has a Return to Player (RTP) rate, which explains the theoretical payout that an average player would receive. For example, if the RTP is 96.5%, you can expect $96.50 back from $100 wagered during an average session. Of course, some players will win and other slots players lose, but high RTP games are desirable. We seek out the best new slots sites offering a variety of high RTP slots. This is a very competitive industry, with lots of new online slot sites battling one another for your business. The best mobile slot sites and desktop slot sites offer large sign-up bonuses – including no deposit bonus offers, match deposit bonuses and bonus spins – to stand out. They also provide recurring, weekly promotions to keep you loyal to the site. We assess the quality of the bonuses from the best online slots sites, seeking out large offers with low rollover requirements. We only recommend online slot sites that are regulated and licensed to operate in the United States. As part of their licensing conditions, they must subject their games to regular, random testing from external agencies. This ensures the games available on these sites are not rigged and they can be trusted to deliver fair results, in line with the stated RTP of the slot. Most of the highest RTP online slots are optimized for mobile play, so they work perfectly on the smaller iPhone or Android device screen. Some of the older slots are only available on desktop sites, so you often find a larger range of games at a desktop casino. However, some games are now specifically designed only for mobile slot sites, so you will need to access the casino via your cell phone to play them. You can also download a native app. It is always worth checking the RTP rate on a game before playing it for real money. There are other considerations when choosing an online slot – the volatility level, the theme, progressive jackpot payouts and so on – but the RTP provides the best indication of your long-term chances of success. The average RTP percentage for an online slot is around 96%, so games with a higher RTP are attractive. For example, NetEnt’s Blood Suckers has a 98% RTP, which is attractive. When you factor in bonuses and promotions and loyalty programs, which can reduce the overall house edge on slots, a game with a 98% RTP gives you a decent chance of earning a profit during a session.
