Check Out the Hottest Slot Games from 2020 & 2021
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 2021 was indeed been a fantastic year for reel-lovers like ourselves and, we assume, you, if you’re reading this!
There are 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. In 2020, 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.

The Top 10 Slots of 2020
Without further ado, here’s our list of the hottest games in 2020. For a brief look at each of these games, please keep reading!
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:
Do you dare step into the terrifying Goblin’s Cave.. where… wait, this Goblin isn’t terrifying at all! He looks like a hippy version of one of the Harry Potter Gringotts goblins. Ah well, this game has taken our top spot in 2020 and there’s a good reason for that – it’s super fun.
Goblin’s Cave is a 3-reel slot with 3 paylines and bets up to €1,500. It includes a fun feature that allows you to hold certain symbols to increase your chances of winning on the next role.

Top Video Slot Game Providers 2020

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.
Now that we’ve got 2020 out of the way, let’s move on to 2021 and see how the data differs. Were your predictions for the 2021 slots right? Keep reading to find out!
