Check Out the Hottest Slot Games from 2020

2020 was a heck of a surreal roller coaster ride so far and no one really knew what was going to happen next… Frogs raining from the skies? The return of Elvis?

All bets were off, but what certainly helped keep our minds off the wacky world is the blissful distraction of epic slot games and 2020 was indeed been a fantastic year for reel-lovers like ourselves and, we assume, you, if you’re reading this!

There’s a lot of top slots to choose from, including the normal perpetually popular slot games such as Book Of Dead, by Play’n Go, or Starburst, by NetEnt. Last year, however, we also noticed that slot players were branching out and trying lesser known, but still great quality games.

If you’re looking for the most popular games offering players the most rewards and entertainment then look no further. We’ve listed the creme-de-la-creme right here for you to see.

Well there it is, the most popular video slots in the world based on our online traffic. As mentioned above, what stood out for us was the presence of some quite old and lesser known slots that have outranked trending and highly-showcased games. Still, none of these slots are too far off the radar and many of the slot veterans in our audience will certainly recognise most, if not all, of them.

There are also a few trusty classics in the list that always find their way into top slots lists such as NetEnt’s Starburst and Gonzo’s Quest and Novomatic’s Book of Ra (one of the more original Indiana Jones copycats out there). Find out more about each slot below:

Top Video Slot Game Providers 2020

X: What a Game Provider is not – Santa. The nice white-bearded and red-robed Christmas guy may have chosen to gift you with a SNES console when you were a little 90s rugrat, but, in the context of online slots, Santa is not a game provider.

: What a Game Provider is – Online Casino Game Developers. That’s right, just like EA Sports is the developer that brings out a slightly-different version of Fifa Football every year, it’s the casino game providers such as NetEnt, Microgaming and Play’n Go that fill up online casinos’ game libraries.

Netent slots

Top 10 Slots of 2020 by Country

Gaming trends, like any kind of trend, vary from country to country. Just like you can be sure that more tea is drunk in the UK per capita than anywhere else in the world, there are also gaming themes that stand true in the world of online gaming.

The Slots Players are Looking For in 2020

If we were to take the results per country and make a conclusion, we could say that players have mostly been looking for new slots in 2020 rather than for timeless classics. With new titles such as 9 Pots of Gold, The Dog House Megaways and Absolootly Mad Mega Moolah coming up trumps.

However, when we look at this data collectively, this doesn’t seem to the be case overall. In fact, players are actually more interested in high RTP slots, such as Goblin’s Cave, as well as ageless successes, including Starburst and Immortal Romance. These findings are also reflected in the monthly search volume figures for 2020.
