One of the most famous progressive jackpot slots of all time, Mega Moolah from Microgaming, has been wowing players with its sensational wins since 2006. Mega Moolah offers an RTP of 88.12% and low volatility. It's a simple 5x3 safari-themed game and remains one of the oldest slots from Microgaming that continues to dominate the charts to this day.
Developed by Microgaming, Immortal Romance is a vampire-themed slot that’s had its fangs in slot fans for years. The game has special features like Wild Desire, which gives you five reel Wilds, a free spins bonus, and multipliers on specific spins. You can immerse yourself in this story of vampiric romance by reading the characters’ backstories on the symbols in the paytable.
Started as one of IGT’s top land-based slots in 2002, Cleopatra jumped to online casinos with its Egyptian themes in 2012. You can hit Wild symbols to boost your winnings or hope for three Scatters to trigger a free spins bonus game. Cleopatra has a minimum bet of $0.20 and a maximum bet of $100, with a medium variance, making it a solid option for all players.
While Book of Ra Deluxe is one of the older games on this list, launched in 2008 by Novomatic, the Egyptian-themed game is still one of the best slots you can play. The game has an RTP of 95.10% and is high variance, which suits big-budget players. Book of Ra Deluxe also has a Gamble Feature, where you can play for more money if you hit a win. The slot will let you predict whether a playing card is red or black, and if you’re correct, you can double your money.
Microgaming’s 9 Pots of Gold is an Irish-themed slot with leprechauns, rainbows, and lucky clover symbols to boot. If you hit three free spins symbols, you can play the game’s exciting free spins rounds with a random multiplier on all wins. As the name suggests, you’re looking to hit nine pots of gold symbols, giving you a win of 2,000x your stake.
One of the online slot giants, Pragmatic Play, takes slot fans on a relaxing fishing trip with Big Bass Splash – a slot game with an RTP of 96.71% and a maximum potential win of 5,000x your stake. You can bet between $0.10 and $250 on each spin, allowing for a sensational maximum win of up to $1,250,000.00. Furthermore, a free spins round is available, which can be triggered by landing Scatter symbols. Alongside these features, there are fish symbols, each carrying a distinct value. These can be collected and stacked by hitting one or more Wild symbols.
An Irish-luck-themed slot from WMS Gaming, Rainbow Riches lets you look for your pot of gold win on 5x3 reels. You can find Wishing Well symbols, which provide multipliers up to 500x your stake. There are no free spin games, but you can claim a $250,000 jackpot if you hit the correct symbols. Rainbow Riches is also well known for working well on mobile devices at mobile casinos online.
If you're a dog person, then you definitely shouldn't miss this popular release from Pragmatic Play. The Dog House Megaways is a charming cartoonish-looking slot game powered by Big Time Gaming's Megaways mechanics, offering up to 117,649 paylines. With an RTP of 96.55%, a highly volatile gaming model, and a maximum win of over 12,000x your bet, it's a slot game that's not to be missed – especially for dog lovers!
Embark on a journey into the Wild West with Nolimit City's gritty and brutal slot, Tombstone R.I.P. This game presents 5 reels in a 2-3-3-3-1 configuration, along with 108 paylines. You can play the Tombstone R.I.P slot for as little as $0.10 or go all in with $50.00 and enjoy its 96.08% RTP, all while aiming for the mouthwatering maximum payout of 300,000x your stake. The slot offers a pack of thrilling bonus features, such as Hang 'em High Freespins, Boothill Freespins, and the Nolimit Bonus, the latter of which can take you into the free spins round for the price of 70x the bet.
If you're a fan of Cluster Pays slots, then you've certainly heard about Reactoonz, a slot with cascading symbols. The game features a 7x7 gaming grid, an RTP of 96.51%, and a high variance gaming model. During the gameplay, once the Quantum Leap feature is charged, you can reap the benefits of one of four features: Implosion, Alteration, Demolition, and Incision. The slot is better suited to players with a bigger bankroll looking to hit the maximum win of 4,750x.
You can play online slots easily by signing up with licensed and regulated slot sites, and there are many reasons why you should. The best online casinos give you access to hundreds, if not thousands, of slot games at your fingertips. Every type of casino player will find something to enjoy.
Similarly, if you’re on the lookout for big wins, paying attention to the RTP may prove worthwhile. A Return to Player (RTP) percentage tells you how much, on average, a slot pays back to players over time. This is not a guarantee but a good measure to see how long your bankroll may last. Physical slot machines usually have an RTP between 80-90%. Meanwhile, the average RTP for an online slot is 96%, allowing you to make the most of your money.

Slots are the most popular online casino game, and thousands of different games are available. For example, if you’re looking for the most significant wins, you can play progressive jackpots, where a portion of the stake of everyone playing goes towards a jackpot anyone can win.
Alternatively, there are many different types of online video slots, including penny slots, which you can play with for as little as $0.01, and Megaways, which can boast up to 117,649 paylines. There are also classic fruities that simply focus on spinning reels and hitting winning combinations. Yet, we are just scratching the surface.
The best slot game for you will come down to personal preference. Penny slots may be perfect for budget bettors. Likewise, high rollers may want to try out high volatility slots, which pay out less frequently but with bigger wins.
There are many factors to consider when it comes to selecting the best slots, including surface-level details like graphics and features. However, you also have to consider the game’s internal workings, like how often it pays out.
Our dedicated experts examine every aspect of games before making our recommendations. Check out the key areas we review and what we look for below.
Online slots are essentially a digital version of classic fruit machines in a land-based casino. The popularity of land-based slot games led many world-class software companies to develop exclusive online slot games tailored to modern customers, with bonus rounds and sharp graphics. Even classic games that have been copied with online versions get a facelift with the addition of Wild symbols, bonus features, free spins, and Scatter symbols.
So, how does an online slot work? Well, you click buttons to determine your stake for your spin and click to spin the reels. Unlike real-life slots, you don’t need to cash out your winnings specifically. Instead, you can close the game and take your profits with you.
Online casinos always look to attract new customers and keep existing players happy, which is why many operators provide generous bonuses. And as the most popular gambling game, you can use most slot bonuses on slots to spin reels while risking less money and potentially making a profit.
Some of the most popular bonuses for slot players include welcome bonuses, deposit matches, no deposit bonuses, and (of course) free spins. While what you need to do to claim these promotions and casino promo codes varies between offers and casino sites, every bonus will give you a chance to play slots with a boosted bankroll.
All casino promotions are great, but free spins are usually the best for slot players. These bonuses are targeted specifically at slot bettors and are generally available on the hottest or most popular slot games.
The crucial thing to remember is there is no way to improve your odds of winning with an online slot. These games use RNGs (Random Number Generators) so that you have the same chance of hitting winning combinations on every spin.
However, there are ways you can make the most of your bankroll, like claiming generous bonuses. You can also consider the volatility of a slot and how it fits your budget, with low volatility best for low-budget players looking to hit frequent wins to keep their bankroll going. Other factors you can consider to get the edge include setting responsible gambling limits on your account to control your bankroll and the RTP of the slots you’re playing.
Although slots outnumber any other online gambling game category, online casinos do not rely on just slots. You will find many types of table games, live casino games (blackjack, roulette, poker, and more), and sometimes also a sportsbook for live sports betting. This also applies the other way round, where even the best online casinos for baccarat will offer a range of slots for you to play.
