Back in March 2003, a 25-year-old software engineer from Las Angeles won $39.7 million. It’s safe to say they have the most popular slot machines in Las Vegas casinos. Even though it isn’t one of the highest payout slot machines, Cleopatra is the most popular slot machine. Its RTP is just 88.98%, unlike the best paying slot machine with an RTP of 96.60% — Wheel of Fortune.

If you open the site of any real money online casino, you are likely to see hundreds of slots. That’s the most popular category of casino games, so all operators are doing their best to add more and more titles that vary in terms of gameplay, themes, and many other factors.

Picking a slot game that’s fun to play and looks good is important, of course, but many players ignore another crucial aspect. Each game comes with a different Return to Player, or RTP percentage. That number determines what percentage of the wagers is returned as prizes. The higher it is, the most generous a slot machine is.

If you want to improve your chances to win, as well as increase the value of all bonuses and promotions you are clearing, you should stick to the high RTP slots at online casinos. They can be a bit hard to find, so I decided to give you a hand.

I have assembled a list of some of the highest payout slot machines in 2020. These high paying online slots have the lowest house edge possible and reward players handsomely. Let’s take a look.

Good Girl, Bad Girl – Highest Payout Slot for US Players

• Theme: Angels and devils
• Sub-Category: Video slots, Progressive slots
• Developer: Betsoft
• Casino: Wild Casino
• RTP: 97.79%

Let’s begin the list of highest payout online slots with Good Girl, Bad Girl. The game was produced by Betsoft and comes with the exceptional RTP of almost 98%. In comparison, most slots out there only return about 92-93% of the wagers, and 95% is considered decent.

The high RTP is not the only advantage of Good Girl, Bad Girl. The game features various mechanics like wilds, scatters, free spins, and even a progressive jackpot.

If you add the nice graphics and animations, it’s easy to see why I decided to include this title. The best news is that Good Girl, Bad Girl is available at Wild Casino, which makes it one of the highest paying slots for US players in 2020.

You can join the casino and see for yourself right now.

Cleopatra’s Gold – One of the Highest Paying Mobile Slots

• Theme: Ancient Egypt
• Sub-Category: Video slots, Progressive slots
• Developer: Realtime Gaming
• Casino: Bovada Casino
• RTP: 95-97.5%

Another excellent option for people looking for the highest paying slot machines in 2020 is Cleopatra’s Gold. The game was developed by Realtime Gaming and has a classic Ancient Egypt theme revolving around the famous Cleopatra.

The return to player can reach 97.5%, which beats almost any other real money slot in terms of generosity. Cleopatra’s Gold is fun to play, too, as it includes wilds, scatters, free spins, and a progressive jackpot.

While the graphics are not the prettiest compared to some other top mobile slots, this is one of the slots with the best payouts available on the go, so I can live with that.

If you can too, you should try Cleopatra’s Gold at Bovada Casino, which is open to players from various countries, including the USA.

Dr Watts Up Slot – Entertaining With High RTP

• Theme: Nutty doctor
• Sub-Category: Video slots
• Developer: Microgaming
• Casino: Betway Casino
• RTP: 97.05%

If you want to combine fun with high payouts, you should most certainly try Dr Watts Up. This Microgaming game returns 97.05% of all bets to the players in the form of rewards and provides endless entertainment through the bonus games and special symbols included.

There are also multipliers and free spins, a large jackpot that could go up to 48,000 coins, and a lot more to experience. Dr Watts Up comes with flexible limits, so it’s a good choice for all kinds of players.

You can find the game in plenty of online casinos, but I recommend you pick Betway Casino. It’s one of the best out there in terms of games, bonuses, and player safety.

Pay Dirt – High Payout Slot With Low Stakes

• Theme: The Gold Rush
• Sub-Category: Video slots, Progressive slots
• Developer: Realtime Gaming
• Casino: El Royale Casino
• RTP: 95-97.5%

Some people think that the highest payout slots online require large bets. That’s not really the case, as many games with at least solid RTP work with small stakes, and Pay Dirt is the best example among them.

This Realtime Gaming product is available to everyone because the lowest coin value is $0.01, and there are only 25 paylines. That means you can cover them all with a stake of $0.25 or even go for one only for $0.01, which is pretty much as low as it gets for video slots in 2020.

A bankroll of 10 or 20 bucks will be more than enough to enjoy Pay Dirt. The slot has a progressive jackpot, free spins feature, wilds, and scatters, so it provides plenty of exciting moments, too.

Inferno Star – One of the Highest Paying Classic Slots

• Theme: Fruit
• Sub-Category: Classic slots
• Developer: Play’n GO
• Casino: Playamo Casino
• RTP: 96%

If you are looking for a classic slot that pays well and uses a simple gameplay system, Inferno Star is one of your best options. The game has only five reels and paylines and no side games, allowing you to focus solely on the reels.

The old-school sensation is completed by the fruit symbols, and there are some nice additions like re-spins, wilds, and scatters for additional fun.

If that sounds like a good slot for you, Playamo Casino is the best play to try it out in 2020.

At the Copa – High Payout Progressive Slot

• Theme: Night Clubs
• Sub-Category: Video slots, Progressive slots
• Developer: Betsoft
• Casino: BetOnline Casino
• RTP: 97.5%

Most progressive slots out there don’t come with a good return, but there are exceptions. One of the best of them is At the Copa. Betsoft’s game has an astonishing 97.5% RTP, which makes it the perfect choice for those who want to go after life-changing jackpots without losing too much in the process.

The design and symbols are also really enjoyable, and the betting limits are flexible. You can start low and go all the way up to $150 per spin. If you add the bonus game, the wilds, and the free spins feature, it’s easy to see why At the Copa is one of my picks for the highest payout slots online.

One of the best places to enjoy the game is BetOnline Casino because of their awesome promotions and a good variety of quality games.
