Top 10 Most Popular Online Slots Of All Times

Slots have come a long way ever since their creation in the late 19th century. The very first slot machines were simple, mechanical devices with only three reels and one pay line. Players would insert a coin, pull a lever on the machine’s side, and hope to get lucky enough to line up three matching symbols. With time, slot machines became more and more popular, and by the 1960s, you could find them in all casinos across the globe.

With the rise of the internet in the 1990s, it was only a matter of time before slot machines made their way online. Today, slots are one of the best casino games for beginners. There are thousands of games to choose from, with a variety of themes, features, and payout structures.

So, what are the top ten best online slots of all time?

1. Starburst

Starburst is quite possibly the most popular and beloved online slot out there. Countless slot enthusiasts are familiar with the game’s classic arcade feel, bright colors, and gemstone symbols. Developed by NetEnt, Starburst has several special features, including expanding wilds, which can cover entire reels and trigger re-spins. In 2021, NetEnt released the game’s long-awaited sequel, Starburst XXXtreme.

2. Mega Moolah

Best known for huge progressive jackpots, Mega Moolah features an African safari theme, with symbols such as lions, giraffes, and zebras. The progressive jackpot starts at a minimum of $1 million and has been known to reach as high as $20 million.

3. Gonzo’s Quest

Also by NetEnt, Gonzo’s Quest follows an explorer searching for a treasure deep in the Amazon rainforest. One of the game’s highlights is the Avalanche feature, where symbols fall into place instead of spinning. Gonzo’s Quest went on to inspire Gonzo’s Treasure Hunt, which is the first ever game with a VR mode.

4. Book of Ra

If there’s an online slot for Indiana Jones and The Mummy fans, that’s Book of Ra. By developers Novomatic, the game has an Egyptian theme and follows an adventurer as he searches for the mysterious Book of Ra. Players are drawn to the game because of its free spins bonus run, which allows them to earn up to ten free spins.

5. Mega Fortune

Mega Fortune is yet another online slot famous for its huge progressive jackpot, which has reached as high as $17 million. The game features a luxury theme, with symbols such as yachts, champagne bottles, and diamond rings.

6. Thunderstruck II

Thunderstruck II is the best slot with a Norse mythology theme. You’ll come across symbols such as Thor, Odin, and Loki. Developed by Microgaming, the game’s best feature is its Great Hall of Spins bonus round, where players can earn up to 25 free spins with a 5x multiplier.

7. Immortal Romance

9. Dead or Alive

Dead or Alive is a simple, yet engaging slot with a Western theme. Players follow a group of outlaws as they navigate a town full of danger. By developers NetEnt, the game features Sticky Wilds, which make wild symbols remain in place for the duration of the bonus round.

10. Mega Joker
