The Best and Highest RTP 🎰 Slots in 2023

There is a lot of thought that goes into playing slots online. These include the theme, game developer, paylines, and choosing a slot game with a high RTP (Return to Player).

With the rise in popularity of online gambling in the United States, online slots have become a favorite among gamblers. Bettors can enjoy some of the best casino slots playing at some of the top online casinos in states such as New Jersey, Pennsylvania, and Michigan. There is no need to visit Las Vegas to experience new slots or play penny slots. Additionally, as the competition in the iGaming industry increases, operators offer bonuses such as a no deposit bonus and free spins to encourage people to sign up and play their slot machines. Some slot games, such as Mega Moolah, have gained a cult following thanks to excellent bonus feature options, progressive jackpots, and a healthy payout percentage.

Because slots have become so prominent, people now want to know things like the top slot machines at each online casino, the highest payout slot machines, and how to tell when a slot machine game is about to hit. Although players enjoy playing exciting slots with a free spins feature, playing slots that are more likely to give them some money is even more appealing. Some of the loosest slots around can be found at online casinos.

This is where RTP (Return to Player) comes into the equation. Every game must have an official Return to Player figure. This is the percentage win rate that a bettor is expected to achieve long term. It is an excellent way to find out which slots are more generous, and is why players are constantly looking for the best RTP slots or the highest RTP slots.

Of course, the casino also must make some money, so naturally, the RTP for all slots is below 100%. With that in mind, you want to find slots with the highest RTP figure possible, which will be the closest to that 100% figure. It is about being as close as possible or having an advantage over the house edge when you include casino bonuses.

This page lists the top 10 online slot titles, including the highest RTP casino slot machines in 2023. If you are looking for the highest payout online slots, you have come to the right place. See below for the highest RTP slots in 2023 available to play in the US.

So let’s break down the games you should be playing if you want to play on slot machines with the highest Return to Player. We also summarize the unique modes and options to look out for when playing, such as the free spins, bonus buys, and special bonus features.

#1 Ugga Bugga – Playtech – 99.07% RTP

Created by Playtech, this unique game is unlike any other slot game. When you play, it feels more like a video poker game where you seek to make winning combinations of symbols but get the opportunity to hold a symbol space, which acts on all ten paylines. You may be put off when you first play as it is an unusual reel layout, but stick with it, as the fantastic RTP means you won’t lose much money as you learn the game. While it might not be the most visually appealing game, you cannot argue with the insanely high RTP value.

#2 OOH AAH Dracula – Barcrest – SG Gaming – 99% RTP

This Barcrest title is a gothic-themed slot where players must match winning ghostly style symbols in Count Dracula’s iconic castle. There is a Graveyard and a Super Graveyard bonus game, and to ramp up the idea of the spooky sentiments of this game, there is also a Heart Attack Bonus. The key feature to note here is the unique Big Bet options (similar to a Bonus Buy) which give you access to the highest RTP on offer and a novel skeleton arm strategy indicator to help you make informed Big Bet choices!

#3 Mega Joker – NetEnt – 99% RTP

This online slot game, provided by NetEnt, has become a cult classic and is loved by slot fans. When you wager the max coin amount, the RTP cannot be beaten. The game features three reels and is a throwback to past slot machines, with a 1960s soundtrack thrown in for good measure. If you win on the base game, you can either collect your winnings or take them to the Supermeter Bonus game. Additionally, there is a progressive jackpot feature with Mega Joker. This game is available at most online casino sites and offers some of the best odds around.

#4 Jackpot 6000 – NetEnt – RTP 98.8%

Another game from NetEnt, Jackpot 6000, is an old-school traditional slot machine with basic gameplay featuring three regular reels and five fixed paylines. Head or Tails gambles help boost your winnings, Joker Symbols act as wilds, and the special Supermeter are key features here. Landing two Joker symbols in the Supermeter allows you to win a selection of mystery prizes that can range from 10 and 6000 coins!

There is some simple strategy involved to play this slot optimally (RTP wise), so read through the paytable instructions and rules to understand how the Coin Gamble and Supermeter feature work fully!

#5 The Catfather – Pragmatic Play – RTP 98.10%

Although similar in name, this is nothing like the famous Godfather movies, as it features cute kittens rather than mafia fights and guns. Bettors can spin across five reels, and nine fixed paylines, with kitties forming winning lines in all directions. You can activate a free spin round with up to 25 free spins on offer and multiply any wins by 4x. If that wasn’t enough, add stacked wild reels that can appear on the middle three reels. A game featuring cute kittens and one of the highest RTP slots; what more could you want?

#6 Rainbow Riches Pick N Mix- Barcrest – SG Gaming – RTP 98%

Another game from Barcrest, Rainbow Riches Pick N Mix, is the sequel to the market-leading Rainbow Riches slot. Players can choose which bonus games to play from 5 different options and activate up to three of them before spinning the reels. You can enjoy shooting for the Magic Toadstool Bonus, the Road to Riches Bonus, the Pots of Gold Bonus, or try your luck on the Free Spins and Cash Crop bonus round. The five unique bonus rounds allow you to pick and mix just how you want this slot to play.

There is also a “Premium Play” option which is similar to the “Big Bet” or “Bonus Buy” features on other slots. Think of it as a fast track to triggering any of your selected bonus rounds and the Mega Spins bonus. Of course, this option also comes with a premium price to play it!

#7 Blood Suckers – NetEnt – RTP 98%

With a superb RTP of 98%, Blood Suckers should earn you a decent payout without sucking the life out of your bankroll. There are five reels, 25 paylines, scatters, and wilds. Players must try to navigate their way through fighting vampires and choosing from coffins to win cash prizes. This NetEnt game is not for the light-hearted, but it’s lots of fun.

Given that Blood Suckers is known as a very low variance slot and has exceptionally high RTP, it has served very well for slot players as a fantastic option for completing casino bonus wagering. Frequent coffin-picking round bonuses and the free spins round help keep the bankroll looking healthy, making this slot well worth checking out.

Just be aware that because of this slot’s proven track record in helping to complete casino bonus wagering requirements, it may be on the list of disallowed slots while a bonus is active; it really is that good in grinding our bonus wagering!

#8 Jokerizer – Yggdrasil Gaming – RTP 98%

Provided by Yggdrasil Gaming, this game with an unusual name is a winner in our eyes. Essentially, Jokerizer is a traditional fruit machine based on the popular “Joker” style slots, complete with lemons and cherries in addition to sevens and bells. Look out for the Jokerizer mode and Mystery Win feature.

With a very high variance, 5 reels, 3 rows, and 10 paylines, this serves as a more modern take on the classic Joker slots but with the same max win potential of 6000 coins and, of course, the fantastic RTP of 98%.

#9 Starmania – NextGen Gaming – RTP 97.87%

Created by Nextgen, this sci-fi-themed game allows you to explore the galaxy far, far away as you try and land sequences of star symbols alongside an upbeat soundtrack. This slot is Nextgen Gaming’s answer to the extremely popular Starburst slot (NetEnt) but with more features, a proper free spins bonus round, and a better RTP!

10 paylines pay in both directions, providing multiple chances to win at the slot machine. Add in stacked wilds and the free spins bonus features, and it becomes one of the most exciting slots out there.

#10 White Rabbit Megaways – BTG (Big Time Gaming) – RTP 97.77%

White Rabbit Megaways truly lives up to its name as it has up to 248,832 ways to win, which explains the fact why this slot game has an excellent RTP. This Big Time Gaming title is inspired by Alice in Wonderland, giving a nod to the classic tale with a Down the Rabbit Hole free spins feature and unique Extending Reels in the bonus round added by the Cupcake Wild symbols. With Extending reels that grow up to 12 rows in size, bonus re-triggers, and extra High paying Queen symbols added, this slot is packed with features that will captivate you.

The addition of a Bonus Buy (Feature Drop) option on this Megaways slot allows you to bypass the base gameplay entirely and head straight into the bonus round for a cost of 100x stake. Playing the base game and collecting gold coins will also reduce the cost of this option!

The maximum RTP of 97.77% is achieved by buying the Feature Drop, but even without this mode, the regular gameplay and standard bonus triggers have an impressive RTP of 97.24%.

What Are High RTP Slot Machines?

The Return To Player value of an online slot game determines the amount bettors can expect to lose when playing a particular slot. It helps to think of RTP as a House Edge but in reverse. For example,  Ooh Aah Dracula has a large RTP of 99.00%. Consequently, the ‘house edge’ will be 1%, and you will get back 99% of your wager over an extended period of play. Therefore, this would be considered a loose slot and one of the best slot titles you could play.

Let’s look at another example. Book of Dead by Play N Go has an RTP of 96.21%, which means the house edge is 3.79% over the player. In theory, you will get back 96.21% of what you wager in this instance.

Essentially, how much you win when playing slot games for real money depends just as much on luck as it does on which slot you choose to play. It is still worth checking out a casino/slot review before you play to see the stated RTP percentages. Still, slot games use Random Number Generator (RNG) technology to ensure everything is random on each spin.

Of course, a high RTP slot is favorable, and the best online slots will have a decent RTP slot payout rate. Any bettor wants as much chance of winning when playing a casino game and the best payout opportunities come with a slot site with a high RTP.

💲 Best RTP Slots

Just because an online slot has a very high RTP, it doesn’t actually indicate whether the slot is fun to play, or has the potential to provide you with huge wins. It does of course let you know that a good percentage of money wagered on it is returned to the player over time. If you are looking for the best RTP slots, in our opinion, they also have to provide you with the potential of winning considerable amounts on them.

Below you will find our top 3 best RTP slots that not only provide an excellent RTP in excess of 95% but are also high variance machines that can be extremely volatile in nature; for this reason, they are more than capable of providing stunning big wins in addition to just having a good RTP.

1. 🥇Dead or Alive 2 (NetEnt) RTP 96.8%
2. 🥈 Rise of the Mountain King (Nextgen Gaming) 96.84%
3. 🥉 Danger! High Voltage (BTG) 95.67%

🥇#1 Dead or Alive 2 (NetEnt) RTP 96.8%

If you are looking for an online slot with high RTP and one that is also more than capable of 1000x stake and greater wins, then Dead or Alive II is your perfect slot. Building on the massive success of the original nine payline machine, this updated version features a graphical makeover, three bonus rounds options, and even more multipliers that give this slot the potential to pay out up to 111,111x stake as a max win.

Players seeking out the most significant wins should opt for the MAX High Noon Saloon free spins, which feature sticky wilds, extra spins, and the addition of extra multipliers.

🥈#2 Rise of the Mountain King (Nextgen Gaming) 96.84%

Rise of the Mountain King plays in a very similar style to the extremely popular 300 Shields slot. The positive here is that this slot has a better RTP at 96.84% when using the Buy Pass feature and can produce wins up to 50,000x stake.

The notable features to look out for are the Kings Re-Spin feature which acts almost like a sticky wild re-spin feature, and of course, the potential of 100x Multipliers in the free spins round. Combining bost of these features together is the key to the biggest wins on this machine.

🥉#3 Danger! High Voltage (BTG) 95.67%

It would feel criminal not to have at least one BTG slot in any best list, and Danger High Voltage! is definitely a more than capable slot of producing huge wins. While the RTP is definitely not the highest at 95.67%, being over 95% is still quite acceptable. Contrary to most BTG slots, this one doesn’t use their Megaways system, but with 4096 paylines, it can still produce some jaw-dropping wins.

Two free spins bonus rounds are offered where you can choose from the High Voltage Spins with insane multipliers that go up to 66x, or the Gates of Hell Free Spins with sticky wilds that can completely fill all the middle reels!

What Is a Good RTP for Online Slots?

A “good” RTP for online slots is a value as close to 100% as possible; The closer this value is to 100%, the smaller the house edge is, and the vast majority of money wagered through the slot is returned back to players. From our years of playing online slots, we tend to draw a baseline value of 95% RTP, offering a decent return, 96% is around the average value for most online slots currently in the US, and anything exceeding 97% RTP is deemed as a fantastic online slot RTP value.

In rare cases, we may choose to play online slots with a slightly lower than 95% value, but only when these are specific games that we genuinely enjoy playing. If you find yourself liking a particular game, but it has a low RTP (lower than 95%), then consider if there are alternatives from different online slot developers that offer the same kind of gameplay and features but with higher returns.

Overall though, it’s down to personal choice where you draw your own line in terms of “Good RTP” as long as you understand the concepts and how RTP is calculated, then you are able to make informed choices regarding your online slot play.
