I’ve put together this list of the highest payout online slots for your convenience. I’ve created two lists to cover both angles; one will show you which slots return the most to players, and the other will show you which slots have the largest jackpots.

It’s important to understand the differences between these two types of slot payouts. Therefore, I’ll start with quick definitions and examples of those. If you already know all about these, skip ahead to the next section to view the highest payout slot machines immediately.

Slot Machine Payouts – Basic Definitions

When you say “the highest payout online slots” you could mean two things:

  1. The slots that return the most to players as a payout percentage (RTP)
  2. The slot machines with the highest payouts and jackpots

Most players understand what jackpots are. That’s the maximum amount you can win on a specific machine. For example, Mega Moolah has a progressive jackpot seeded at $1,000,000. It can grow much bigger than that, but that’s the minimum amount you’ll win.

However, many new players don’t understand RTP. This is expressed as a percentage. It tells you how much a slot is programmed to pay out over the long term.

For Example:

Starburst slot has an RTP of 96.09%. That means it has an average payback rate of $96.09 for every $100 wagered.

Now that you understand these definitions, let’s look at popular slot games from both angles.

Slots With the Highest RTP

Slot Software Payouts USA Players Where to Play
Mega Joker NetEnt 99% No Betway
Paydirt RTG 97.5% Yes El Royale Casino
Diamond Dozen RTG 97.5% Yes El Royale Casino
Enchanted Garden RTG 97.5% Yes High Country Casino
Jack Hammer 2 NetEnt 97.07% No Betway

Let me also give you a quick explainer for each of these slots and what you can expect from them:

  • Mega Joker – If you like classic slot games, this one will be right up your street. It’s a three-reel slot machine with classic symbols such as bells, sevens, bars, and cherries. When you win, you can risk it in the Supermeter bonus round or collect your cash. It’s one of the highest payout video slots of all time.
  • Paydirt – This is a high payout RTG slot themed on gold mining. You’ll see gold nuggets, gas lamps, dynamite, and familiar mining objects on the reels. It offers 12 free spins in the bonus feature, the entire middle reel can run wild, and there’s a picking round with instant cash payouts.
  • Diamond Dozen – This game has a luxurious theme celebrating the lifestyles of the wealthy. You’ll see diamonds, expensive purses, and expensive items on the reels. It has a free spins bonus round with all wins doubled, and it’s a progressive jackpot slot game. You can see the jackpot growing above the reels as you play.

  • Enchanted Garden – With a mystical, magical theme, this slot features treasure chests, mushrooms, spell books, fairies, and more. It has a free spins bonus round and a progressive jackpot that you can win on any spin.
  • Jack Hammer 2 – This game has an old-school detective theme in a comic book style. It offers lots of re-spins with sticky symbols and a free spins feature with up to 40 gratis spins and all wins doubled. It’s one of my favorite high payout slot games.

Now, let’s turn our attention to slot machines with the largest jackpots.

The Highest Payout Online Slots – Jackpots

Wouldn’t it be nice to click spin and find yourself hundreds of thousands or even millions better off a few seconds later? That’s what all slots players dream of, and I’ve read enough media stories to know that it does happen for some lucky players.

I wanted to find out what slots pay the most if you do get lucky. After researching, I came up with this list.

Slot Game Software Jackpot USA Players Where to Play
Mega Moolah Microgaming Progressive No Betway
Mega Fortune NetEnt Progressive No Vegas Hero
Major Millions Microgaming Progressive No Betway
Hall of Gods NetEnt Progressive No Vegas Hero
Arabian Nights NetEnt Progressive No Genesis Casino
Cleopatra’s Gold RTG Progressive Yes El Royale Casino
Aztecs Millions RTG Progressive Yes High Country Casino
Jackpot Pinatas RTG Progressive Yes El Royale Casino
Shopping Spree RTG Progressive Yes Bovada
Megasaur RTG Progressive Yes El Royale Casino

As these are progressive jackpot games, most of them have jackpots worth millions. Mega Moolah, for example, has a jackpot seeded at $1,000,000. It can grow MUCH larger than this, but Microgaming put up $1,000,000 to get the ball rolling.

In case you’re wondering what progressive jackpot slot to play, this should help you make your mind up.

  • Mega Moolah – This is an incredibly simple slot with a wildlife and safari theme. It has a free spins feature, wilds can multiply wins by 2x, and it has a bonus wheel feature with millions up for grabs. This is one of the highest payout online slots of all time and currently holds the record for the largest jackpot ever paid online.
  • Mega Fortune – Wealth, luxury, and high-ticket items set the atmosphere in this game. It has a free spins feature with large multipliers and a bonus wheel game with three progressive jackpots. If you win the Mega jackpot, you’ll be an instant millionaire.
  • Major Millions – This is a slightly dated classic slot with a cartoon military theme. It’s extremely basic, but don’t underestimate it. The Major Millions jackpot regularly climbs to seven figures.
  • Hall of Gods – With a theme that celebrates ancient Norse gods, this is a visually stunning game. It has a free spins feature with up to 20 free spins and 3x multipliers. You can also win instant millions by smashing shields with Thor’s iconic hammer.
  • Arabian Nights – NetEnt takes you to Ancient Arabia in this progressive jackpot slot. It’s basic, with only one feature; it’s a free spins bonus round with up to 15 free spins and 3x multipliers. However, you can win millions on any random spin, which makes it well worth playing.
  • Cleopatra’s Gold – This slot celebrates one of ancient Egypt’s most infamous rulers. You can win lots of free spins with large multipliers, but it’s all about the progressive jackpot. You could win hundreds of thousands on any spin. Make sure you pick the jackpot version of this game.
  • Aztec’s Millions – This slot is set in the jungles of South America and has a phenomenal theme. You can win up to 25 free spins in the bonus round. However, the highlight is the progressive jackpot. It’s seeded at $1 million, but at the time of writing, it’s triple that amount. It’s one of the highest payout online slots for American players.
  • Aztecs Millions Slot Game

      

  • Jackpot Pinatas – Take a digital vacation to Mexico in Jackpot Pinatas. It celebrates Mexican festivals with elements like limes, chilis, fireworks, maracas, and sombreros on the reels. You can win up to 25 free spins with double wins and a progressive jackpot seeded at $250,000. The jackpot regularly climbs into the millions.
  • Shopping Spree – The name of this slot perfectly summarizes what you’ll be doing if you win its progressive jackpot. It’s one for the ladies, with handbags, high heels, lipsticks, and flowers on the reels. It has a picking bonus game with instant cash prizes and a progressive jackpot that can climb into the millions.
  • Megasaur – Transport yourself digitally to the Jurassic era by playing Megasaur slot. You’ll see all kinds of dinosaurs on the reels. You can win up to 50 free spins and the Megasaur jackpot is almost always worth hundreds of thousands minimum. Winning that would make a few bills extinct, wouldn’t it?

The Highest Payout Online Slots of 2020

I’ll keep this post updated as operators release new slots with high payouts. For now, these are the best slots you could play both from a payback perspective and for a chance to win life-changing jackpots.

Remember that all of the casinos listed above offer generous welcome bonuses, and you’re entitled to claim them all. Why not create multiple accounts, claim as many free spins bonuses as you can, and try all of the slots I’ve mentioned here?

Good luck, and I hope that soon I’m reading about you as the next lucky slot player who won hit the big time!
