Most Popular Online Slots of All Time

There are few areas of the global entertainment industry that are as varied and as extensive as the online casino slot sector. After all, there are literally tens of thousands of different online slot games out there, with hundreds of new ones being created every single day.

What’s more, there is a huge amount of money at play in the online slot industry, which is why there are countless game development studios all vying to create the very best slot games to sell to the biggest online casino platforms.

But how can a young, ambitious slot game developer learn what it takes to develop a smash-hit slot game? For starters. they can look at the most successful and widely played slot games of the past decade to see what it is that makes them so popular. 

1. Gonzo’s Quest

There probably isn’t any other slot that is as iconic or instantly recognizable as Gonzo’s Quest, a 5-reel slot produced by NetEnt that is available at top casinos like Betfair. In this classic slot, you step into the shoes of the Spanish explorer Gonzo on his quest to uncover the unparalleled riches of the mythic city of El Dorado. While the theme is certainly an attention grabber, it’s the unlimited cascading wilds that keep players coming back for more. 

2. Starburst

Sometimes the classics are not to be messed with. This is certainly true when you look at the astonishing success of Starburst, another NetEnt title that keeps things simple with classic retro music and imagery, evoking that all-important nostalgia factor. In addition, this slot allows players to win up to 50,000x their original bet, which is more than enough to keep them coming.

3. Mega Moolah

The past few years have shown us just how popular progressive jackpot slots – games where all players can also play for a collective prize pool – really are. Mega Moolah is, as the name suggests, one of the biggest jackpot slots in history, with a top payout of €10 million to the one lucky player who manages to hit the big win. While there are many other ways to win, it’s this unparalleled jackpot that helps explain the enduring popularity of Mega Moolah. 

4. Book of Ra

For some reason, any slot game with an Ancient Egypt theme just seems to be a massive success. Perhaps it’s the exclusivity and glamor associated with historical titans such as Cleopatra and Nefertiti. Perhaps it’s the strong associations we all have between Ancient Egypt and treasure-filled secret rooms. Whatever the reason, the 5-reel Book of Ra slot, with its tomb-raiding themes, continues to be a standout success. Complete with scarabs, jewels, and mummies galore, the Book of Ra slot gives players the chance to win 50,000x their stake, which is pretty hard to pass up. 

The online casino gaming industry is a highly competitive business. However, any game developer that pays attention to what these successful slots have done right will be setting themselves up for success.
