| Starmania | NexGen Gaming | 97.87% | Low-medium | 500x |
| White Rabbit Megaways | Big Time Gaming | 97.72% | High | 10,000x |
Note: These online slots are available at real money casino apps in the US. If you’re looking for high RTP slots at social and sweepstakes casinos, the best options include Book of 99 (99%), Money Cart (98%), and Money Cart 2 (98%) by Relax Gaming, Quest to the West (97.53%) by Betsoft, and Joker’s Million (97.34%) by BGaming.
Now, let’s look at each of these slots in a little more depth:
Monopoly Big Event
You will need to activate the “Big Bet” feature to increase the RTP rate to 99% on this 5-reel, 20-payline slot from Barcrest. Monopoly Big Event is a medium volatility slot, which should appeal to fans of the classic board game. When you activate the “Big Bet” feature, you will receive five premium spins, with special modifiers.
Mega Joker
The RTP can go up to 99% on this highly volatile NetEnt slot if you select the “Supermeter” mode. Mega Joker is an unusual slot, so it’s helpful to play the game in demo mode before switching to real money play when you’ve mastered the format.
Dr. Jekyll Goes Wild
Dr. Jekyll Goes Wild is another high RTP slot from Barcrest, which is one of many studios owned by Light & Wonder. Once again, players must activate the “Big Bet” feature to benefit from the maximum 98.2% RTP rate. It’s a pretty simple 5-reel slot, with medium volatility and a fun bonus round.
Blood Suckers
This old-school slot from NetEnt has a 98% RTP rate and a low level of volatility. That makes it popular with players working on the wagering requirements attached to online casino bonuses. The graphics are a little dated, as Blood Suckers was released in 2013, but the gameplay is still smooth.
Codex of Fortune
Codex of Fortune has a variable RTP rate, but it can go up to 98% if you grind away for a while. The goal is to collect special symbols, crack a cryptic code, and advance to higher levels of the game. Codex of Fortune has a high volatility rate, and you can win up to 10,000x your bet.
Legend of Bigfoot
Embark on a hunt for the sasquatch by playing this simple 5-reel, 20-payline online slot from Barcrest. Legend of Bigfoot should appeal to anyone that enjoys Monopoly Big Event and Dr. Jekyll Goes Wild, as the format is similar and there’s a “Big Bet” feature, which unlocks the 98% RTP percentage.
Starmania
A low volatility slot from Light & Wonder’s NextGen Gaming studio, which has an attractive 97.68% RTP rate. Starmania should appeal to fans of the iconic Starburst slot from NetEnt, as it has a similar outer space theme, but the theoretical payout rate is far more appealing on Starmania.
White Rabbit Megaways
White Rabbit Megaways is an entertaining slot from Big Time Gaming, which offers 248,832 ways to win. The volatility is high, but you can win up to 17,420x your bet. If you activate the bonus buy feature, the RTP will increase from 97.24% to 97.72%.
Medusa Megaways
Another great option for anyone that enjoys Megaways slots. This Ancient Greece-themed game from NextGen has 117,649 potential paylines and a maximum win of 50,000x your bet. If you buy the bonus feature, the RTP on Medusa Megaways increases from a pedestrian 96.28% to a far more attractive 97.63%.
Wild Play SuperBet
This is a fun video slot with a retro theme, simple gameplay, and lots of multipliers. The volatility is high on this NextGen Gaming slot, which offers a maximum win of 1,176x your bet and a strong RTP rate.
What is a good RTP Percentage for slots?
The average online slot has a 96% RTP percentage. That’s significantly higher than the payout rates on slots at land-based casinos. For example, physical slot machines on the Las Vegas Strip had a 91.9% payout rate in 2024, according to the University of Las Vegas.
A good RTP percentage for an online slot would be 96.5% to 97%. It’s pretty unusual to find slots with RTP rates of more than 97%, so they are always attractive. However, there are other factors to consider when selecting a game, such as progressive jackpots, volatility rates, and how to win at slots.

Expert insight:
These online casinos are all fully licensed and regulated in multiple states. They offer large bonuses, secure payouts, high-quality software, and several high RTP slots.
I’d highly recommend downloading the bet365 Casino app, as it clearly displays the RTP rate under each game. That makes it easy for you to identify the best RTP slots. However, it’s only available in New Jersey and Pennsylvania. By contrast, DraftKings Casino and BetRivers Casino are both available in five states, and they both offer many of the best RTP slots.

What is RTP for online slots?
Each online slot has a theoretical return to player (RTP) rate. It tells you how much a player with average luck can expect to receive when playing the game over a prolonged period of time.
For example, if a slot has a 96.2% RTP rate, you will expect to receive $96.20 back from every $100 wagered if you have average luck. The results are always totally random, meaning that some players will win, and others will lose. However, selecting the best RTP slots will theoretically boost your chances of success.
The RTP also tells you the house edge on an online slot. For example, if a slot has a 96.35% RTP rate, it means the house edge is 3.65%.
Expert tips for playing high RTP slots online
These tips can maximize your chances of success when playing online slots. Just remember that success is never guaranteed, so it’s important to gamble responsibly.
Check game RTP rate
Check the RTP rate before playing an online casino game. You can find it by tapping the information button or by visiting the provider’s website.
Try demo version first
Play an online slot in demo mode to familiarize yourself with the gameplay, the volatility, and the bonus features. If you enjoy the experience, you can switch to real money play.
Activate features that increase the RTP rate
You may need to activate the bonus buy feature or the “Big Bet” feature to benefit from the maximum RTP rate on an online slot. It’s helpful to take advantage of any features that increase the theoretical RTP percentage, but make sure you plan your budget accordingly.
Check bonus T&Cs
You’ll often find that the best RTP slots are excluded from bonuses. For example, you can’t play Blood Suckers when working on the wagering requirements attached to the BetMGM Casino welcome bonus. It’s important to check the terms and conditions before playing high RTP slots with bonus credits, as you need to make sure they contribute.
