1. Starburst

When it was originally released in 2012, Starburst quickly rose to the top and has maintained that position ever since. This classic online slot game epitomizes why slots are more popular than many other casino games. 

It’s got a simple design and rewarding payouts; it’s easily accessible and has straightforward gameplay.

2. Rich Wilde and the Book of the Dead

Play’n GO is one of the top developers in the online casino industry and continues to produce hugely popular online slot games, such as Rich Wilde and the Book of the Dead. 

In this title, Rich Wilde heads off to Egypt in search of riches from times gone by. The game has rich and detailed graphics, with symbols such as Anubis, a scarab beetle, and the Book of the Dead on the reels. The game takes place in a stunning ancient tomb. 

An immersive storyline, strong gameplay, excellent features, and a free spins bonus round are just a few of the aspects that keep players coming back time and again. The max win of 5,000x the original wager is certainly worth a go, too.

3. Bonanza Megaways

Bonanza Megaways is one of Big Time Gaming’s most popular slots, and it’s the game that kicked off the Megaways Craze. The unusual grid layout, exciting cascading reels, and numerous ways to win have cemented this game as a player favorite.

There’s a generous free spins round, a multiplier meter, and a free spins scatter that can all combine to potentially help you win the fixed jackpot or get the maximum win. The game’s gold rush theme indicates its generous nature to those lucky enough to strike gold on its reels.

4. Gonzo’s Quest

NetEnt’s first platinum slot game, Gonzo’s Quest, remains a player favorite despite being released in 2011. Gonzalo Pizarro is the 16th-century Spanish conquistador who you’ll join on his adventures to find riches in the Aztec city of gold, El Dorado.

The excellent 3D graphics were ahead of their time and are still excellent today. You can expect coins and ancient golden symbols on the reels in a lush rainforest with El Dorado in the background. There’s an exciting Avalanche feature, the Free Falls bonus feature, and generous wild symbols that boost your chances of hitting the big time. 

5. Primate King

Red Tiger takes you over to King Kong’s Skull Island, a primate-shaped cave filled with skulls and other human bones. Primate King, another hugely popular slot, is based on King Kong, and you can expect symbols like treasure chests, maps, snakes, compasses, and Kong himself on the reels.

Random gold coin symbols that can unlock rewarding upgrades, the generous Primate Wild, and the Primate Smash bonus round are exciting gameplay features you can look forward to in this slot game.

6. Gonzo’s Quest Megaways

The original was so popular that Red Tiger created another version, providing fans with Gonzo’s Quest Megaways. Of course, the Megaways mechanic offers you 117,649 ways to win, but that isn’t even the most exciting aspect of the game.

This slot is packed with incredible features such as the avalanche feature, avalanche multiplier, earthquake feature, unbreakable wilds, and the free fall bonus round offering free spins. Not to mention the huge progressive jackpot on offer.

This is everything you’d expect from an upgrade of the original Gonzo’s Quest; it’s got new and exciting graphics and features without losing the original soul that made the game so popular.

7. Mercy of the Gods

NetEnt has done it again with Mercy of the Gods. This developer’s online slot skills seem boundless, and this is another detailed, visually stunning slot that comes with an engrossing storyline.

In this game, you’re off to ancient Egypt once again. In an old tomb or temple, the reels are filled with everything you’d expect, from scarab beetles to the Eye of Horus. It’s stacked with exciting features, too. There’s the Gift of Life respins, the Gift of Double wilds feature, a free spins round, and the Gift of Wealth jackpot game. You could also trigger the massive progressive jackpot that is in play in this game.

8. Big Fishing Fortune

Big Fishing Fortune is an entertaining slot game that is set beneath the sea. It’s got a highly stylized look, and while the graphics are super simple, they are done well. You’ll find a variety of different-sized yellowfin tuna on the reels. The bigger the fish, the higher its value. Of course, there’s also a fishing rod, floats, and some card symbols on there, all with the sound of a fisherman casting in the background.

The standout features of this game include the Big Fishing Fortune Bonus Entry, the Big Fishing Fortune Bonus Match 3 Game, the Big Fishing Fortune Bonus, and the Spin Chance round.

9. Plenty O’ Fortune

Plenty O’ Fortune is the right slot for you if you’re after Irish luck. While the overall maximum win isn’t the largest, it’s a relatively generous slot in frequency, and you can expect some nicely balanced wins.

In the Emerald Isles, the reels are set against lush green hills, and a mischievous leprechaun is on hand to help out. Symbol-wise, you can expect a wishing well, a rainbow, and a pot of gold. 

This game has some exciting features, with three bonus symbols that can trigger a number of additional features and bonuses. Then there’s the Wishing Well Bonus round and the End of the Rainbow Bonus round, which offer simple and exciting gameplay.

10. Raging Rhino Megaways

Raging Rhino Megaways is an entertaining redo of the original Raging Rhino, one of the most popular online slots games. The game uses a classic Megaways mechanic, which gives you 117,649 win ways.

The game is set on the African plains, and the visuals remain true to the original. With a savannah background, you can expect the same animal symbols — crocodiles, cheetahs, gorillas, and rhinos — but they have just been upgraded.

The game is rich in features and includes a cascading reels mechanic, a free spins feature, the Raging Rhino multiplier wild, and the bonus guarantee feature. It’s well adapted to mobile gaming, too, and you can enjoy it from various devices.
