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

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. Additionally, as the competition in the iGaming industry increases, operators offer bonuses such as a no deposit bonus free spins to encourage people to sign up and play their slot machines.

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

This is where RTP play (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. It is an excellent way to find out which slots are more generous and is why players are constantly on the lookout 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 even having an advantage over the house edge.

On this page, we will provide a list of the top 10 slot titles, which includes the highest RTP casino slot machines in 2021. If you are looking for the highest payout online slot, you have come to the right place.

Highest RTP Slots

So let’s break down the games you should be playing if you want to play on the slot machines with the highest return to player.

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 so unusual, but stick with it as the fantastic RTP means you won’t lose a lot of money as you learn the game.

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.

Mega Joker – NetEnt – 99% RTP

This game, provided by NetEnt, has become a cult classic and is loved by slots fans. When you wager the max coin amount, the RTP cannot be beaten. The game features three reels and is a throwback to slot machines of the past, with a 1960s soundtrack thrown in. If you win on the base game, you can either withdraw your winnings or take them to the Supermeter bonus game. Additionally, there is a progressive jackpot feature with Mega Joker.

Jackpot 6000 – NetEnt – RTP 98.8%

Another game from NetEnt, this is an old-school classic slot with the basic game featuring three reels. If you play the max coins, you can trigger the Supermeter bonus game across the top of the screen.

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, with kitties forming winning lines in all directions. You can activate a free spins round and multiply any wins by four. A game featuring cute kittens and one of the high RTP slots, what more could you want!

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

Another game from Barcrest, this is the sequel to the market-leading Rainbow Riches. Players can choose which bonus games to play, as long as you can activate them, of course. You can enjoy shooting for the Magic Mushroom Bonus, the Road to Riches Bonus, or the Pots of Gold Bonus.

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.

Jokerizer – Yggdrasil – RTP 98%

Provided by Yggdrasil, this game with an unusual name is a winner in our eyes. Essentially, Jokerizer is a traditional fruit machine, complete with lemons and cherries in addition to sevens and plus bells. Look out for the Jokerizer mode and Mystery Win feature.

Starmania – NextGen Gaming – RTP 97.87%

Created by Nextgen, this sci-fi-themed game gives you the chance to explore the galaxy far, far away as you try and land sequences of star symbols alongside an upbeat soundtrack. There are ten paylines paying in both directions, providing multiple chances to win. Add in stacked wilds and the free spins bonus features, and it becomes one of the most exciting slots out there.

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

Megaways truly lives up to its name as it has up to 248,832 ways to win, which explains the fact this slot game has an excellent RTP.
