Best Online Slots – All-time Roundup

Let’s not beat around the bush and introduce you to our selection of the most popular online slots with big wins! Strap in!

Mega Fortune – The Mega Millionaire-maker

  • RTP: 96.6%
  • Volatility: Low
  • Provider: NetEnt
  • Release Date: Jan 23rd 2009

The progressive slot Mega Fortune will dip you into the world of luxury. This game scraps the traditional reel symbols for shining limousines, expensive rings, and fancy watches. All this glitz and glamour is your first sign that Mega Fortune is, in fact, a mega fortune-bringer. 

The game’s progressive jackpot, which grows with each wager until a lucky player wins the top prize, is what really draws people in. You can win up to 2165x your wager. There are an additional two jackpots, albeit smaller, which can also drop into the palms of your hands at any moment.

Let’s talk a little bit about that huge bonus for a second – when you enter the jackpot feature, you’ll see a wheel of fortune with three rings. The goal is to reach the inside ring, offering the biggest prizes. The outer ring will award you a prize for certain, so don’t worry about walking out empty-handed. The good thing about this slot game is the low volatility, allowing you to win more often and thus increasing your chances of snatching that jackpot.

Book of Dead – Unearth the Ancient Treasures

  • RTP: 96.21%
  • Volatility: High
  • Provider: Play’n GO
  • Release Date: Jan 14th 2016

Does Book of Dead look familiar? That’s probably because it was inspired by the 1999 film The Mummy. And honestly, what’s more exciting than an ancient Egyptian theme and some sacred relics to uncover? Here we step in the shoes of Rich Wilde, an explorer of tombs and, as you can probably guess from his surname, one of the most important symbols in the game.

While Book of Dead is not a progressive jackpot slot, it is one of the most popular games to this date. It is often paired with free spins casino bonuses, thus increasing your chances of winning big. Despite only having ten pay lines, a low number compared to games like Starburst, its free spins feature and high volatility make it worthwhile. 

The Book of Dead slot game became so popular that it inspired several sequels worth checking out. If you enjoy Book of Dead, why not try Book of Ra, Rich Wilde and the Tome of Madness, and River of Riches?

Starburst – The Cosmic Spectacle

  • RTP: 96.1%
  • Volatility: Low
  • Provider: NetEnt
  • Release Date: Jan 15th 2012

Perhaps the most straightforward game on this list, and perfect for beginners, is Starburst. It was one of the first games to award massive wins for players, and back in the day, it had a volatility of 88%. The game developers quickly discovered the slot continues to be a fan-favorite and updated its RTP so it stays relevant to other online slots in the genre.

The cosmic theme and brilliant colors of this slot machine provide a fascinating experience for gamers. To increase your possibilities of astronomical wins, the Starburst Wild feature extends to take up the full reel.

Starburst is a 5-reel, 10-pay line slot that includes vivid gemstone symbols and an expanding wild feature that can trigger re-spins and improve your chances of scoring huge payouts. Despite lacking a progressive jackpot, Starburst remains a player-favourite among those looking for dependable returns. Its high win frequency and entertaining gameplay make it a beloved game worldwide.

Gonzo’s Quest – The El Dorado Quest

RTP: 95.95%

Volatility: Mid/High

Provider: NetEnt

Release Date: July 15th 2011

The last online slot on our list features another explorer in search of treasures – Gonzo. The character is inspired by the famous Gonzalo Pizarro, a Spanish conqueror who lived in the 16th century. If you aren’t familiar with this piece of history, Pizarro hears of a land place El Dorado, a city made of gold. 

Gonzo’s Quest begins outside this same city, where you have a chance to explore its hidden treasures. The Avalanche feature in Gonzo’s Quest is a ground-breaking innovation. It causes winning symbols to burst, allowing room for fresh ones to take their place. 

That way, you have the opportunity to potentially form a string of wins with escalating multipliers. This is a big part of the reason Gonzo is on our list of online slot games with the biggest wins. Think of the opportunities you have with all these winning combinations!

Where to Play These Popular Slots?

Now that you have our roundup of the top online slot games with big awards, you are probably wondering where you can test them out. With the growing popularity of online casino games, it’s getting increasingly hard to find reputable online casinos.

If you are looking to play in online licensed casinos, we recommend you check out The website is named after yet another incredible slot with a great RTP of 96.6% (which you can also try for free on the website).

What Are RTP and Volatility?

We want to complete this article by explaining two very important concepts. If you decide to look for high-paying online slots on your own, you need to understand RTP and volatility. You probably noticed we included these metrics before every online slot in our list. These concepts can give hints as to how slot games award their wins.

RTP (short for return-to-player) is a percentage representing the amount of your wagers that you will receive back when you play the game. However, since this is a statistical percentage calculated on average after millions of spins, players can expect a higher or lower RTP when they play short-term.

So to give an example, the Book of Dead has an RTP of 96.1%. Technically, for every 100 you spend, you should expect 96.1 back, but this isn’t always true in practice. That’s why it’s always best to choose online slots with high RTP scores. Your returns will be higher overall.

Additionally, it’s important to also take a look at volatility. Low volatility means that you will receive winnings more often but in smaller amounts. Whereas high volatility means you can get bigger wins less frequently. Ideally, you should pick online slots with medium volatility, but these are few and far between.

Now that you are familiar with these concepts, you are ready to play slots online and discover new titles on your own!
