15 Coolest and Most Popular Online Slots
Hey, slots fans! In this blog, I’m going to cover some of the greatest and juiciest online slots games because that’s just how I like to roll. No time to beat around the bush, I’m going straight in for the kill, starting with…
1. Mega Moolah (Microgaming)
This legendary slot machine became famous worldwide in 2015 when a British soldier John Haywood scored a staggering €17,879,645, a little over $20 million! For a long time, Mega Moolah played the part of Mega Fortune’s big jackpots’ main competitor.
Mega Moolah is an African safari-themed slot, that will get you 15 free spins if you land at least 3 scatters simultaneously. During the free spins phase, all wins are tripled, and those free spins are re-triggerable. There are 4 progressive jackpots at our disposal, all of them contained in a randomly activated bonus round.
- RTP: 93,42%
- Volatility: Medium to high
- Reels and paylines: 5 reels and 25 paylines
- Maximum win: 1,955 times the stake (jackpots excluded)
- Min/Max bet: $0,25 to $6,25
- Features: Progressive, bonus game, wild symbol, free spins, multiplier.
2. Book of Dead (Play’N Go)
When someone says ‘Egyptian-themed slot’, and there are tons of them on the market, Book of Dead is probably the one we all think of, right off the bat. Granted, it was one of the first-ever made, but it’s the features, graphics, and the overall atmosphere that kept players wanting for more all this time.
One of the coolest things about Book of Dead is the possibility to customize 10 paylines you bet on. The book symbol serves both as a scatter and a wild symbol, meaning it can mimic all other symbols and if you land a minimum of three you’ll receive a payout, and activate free spins round. A randomly chosen special expanding symbol will be chosen before free spins start to roll, and if it forms part of a win it will cover the whole reel and/or reels it is located on. Additionally, five scattered symbols will get you a multiplier of 200x, and there’s even a gamble round as well if you feel like it’s time for double or nothing.
- RTP: 96,21%
- Volatility: High
- Reels and paylines: 5 reels and 25 paylines
- Maximum win: 5,000 times the stake
- Min/Max bet: $0,10 to $50
- Features: Bonus game, wild symbol, scatter symbol, multiplier, free spins, gamble, expanding wilds, the top prize.
3. Gonzo’s Quest (NetEnt)
Probably the most politically controversial slot machine of them all, Gonzo’s Quest follows the adventures of a real-life conquistador Gonzalo Pizzaro throughout South America. So, strictly historically speaking, Gonzo is the bad guy in this story, in case that someone has already pondered on that thought.
Regardless, this slot is insanely popular thanks to a couple of cool features, with Avalanche multipliers being the top one. The reels will start to move like an avalanche, in a cascade, and if you land four avalanches you’ll win a 5x multiplier. Thanks to its popularity, Red Tiger Gaming made a variant of this game called Gonzo’s Quest Megaways, which relies on the Megaways slot mechanics.
- RTP: 95,97%
- Volatility: Medium to high
- Reels and paylines: 5 reels and 20 paylines
- Maximum win: 2,500 times the stake
- Min/Max bet: $0,20 to $50
- Features: Wild symbol, scatter symbol, multiplier, free spins, cascading, increased multipliers.
4. Book of Ra (Novomatic)
There’s something enchanting about Egyptian-themed slots, and popularity polls don’t lie. Book of Ra is still one of the most beloved slots on the market, with big payouts and numerous bonus features. It has an interesting story and exciting gameplay, although jackpots are truly hard to score.
Book of Ra will get you 5,000 times your line bet if you land 5 archaeologists at the same time, but your best chance for big money is the free spins feature. All you have to do is land 3 scatter books minimum, and the pages will flip and randomly select which symbol will expand over the course of 10 free spins.
- RTP: 95,5%
- Volatility: High
- Reels and paylines: 5 reels and 9 paylines
- Maximum win: 10,035 times the stake

5. Wolf Gold (Pragmatic Play)
People claim you can feel the ancestral spirit of Native Americans as you play this fantastic slot. So, if being a gambling shaman seems tempting, you will need the help of the lone wolf – a wild symbol that can substitute all symbols except scatter and money. If you land three scatter symbols a free spins round will be activated, with additional spins for each new scatter.
Money Moons become active during in-game nighttime, and with each spin, the Moon randomly takes value from a predefined set of major and mini jackpot values. Re-spin will be activated if you land six or more Money Moons. There are three of them at the start, and each new Moon will stay on the reels until the end of the round. One Moon will set the counter back to three, and if you are super lucky and get to land all 15 Moons – start celebrating, it’s Mega Jackpot time.
- RTP: 96,01%
- Volatility: Medium
- Reels and paylines: 5 reels and 25 paylines

6. Elvis Frog in Vegas (BGaming)
What’s better than visiting the City of Sin as the King of rock? Well, according to BGaming, it’s going to Vegas as a frog impersonator of Elvis Presley. This colorful, a bit weird game became popular very quickly, thanks to vibrant graphics, catchy sound effects, and potential prizes.
As usual, Elvis Frog is the wild, and a star from the Vegas Walk of stars is the scatter that starts a bonus round. 5 spins can be triggered by landing 3 scatters on reels 1, 3, and 5. Coin respins will be activated upon landing 6 coins in a single spin, a feature that can be used both in the main game and the bonus round. Coin re-spin phase can get you one of the three jackpots: Mega, Major, and Mini, with the first one being the hardest to hit, taking all 15 coins.

7. Starburst (NetEnt)
As soon as we see gemstones from space, dark stary background, and futuristic music, we know what we are dealing with. Starburst is practically a living casino legend, with many casino bonuses and promotions tied to its name. If you are a passionate slot player, there is no way you could escape playing Starburst, whether you like it or not.
Next to both ways payouts, Starburst’s trademarks are expanding wilds. This feature occurs when one or more wilds land on reels 2, 3, and 4. At that point, wilds will expand and cover the entire reel. Other reels will continue to spin trying to land another wild symbol. If that happens during the re-spin, it also expands and stays active alongside other expanded Starbursts for yet another re-spin.
As mentioned earlier, the Starburst slot pays both ways.
In most cases, a slot machine will pay you if you land 3 or more identical adjacent symbols starting from the left reel to the right, but on a Starburst slot, your winning spin can land the same symbols starting from the right side of the screen to the left. This is a rare slot machine that is loved both by pros and amateurs, and if you are looking for a maximum win you will have to land 5 adjacent bars on an active payline.

You can choose between x20 and x25, the first will grant you the ability to buy free spins rounds, and the latter will double your chances to score a free spins round.
