On Google, a search for the “Top casino themes in 2020”, you get a wide range of hits concerning the popular slot themes in 2020. The criteria used to select these “popular themes” did vary. One of the criteria used to determine top casino themes was “about of payout”. The Ugga Bugga and Mega Machines have a 99% RTP (real-time payout). So obviously these machines are popular when people are winning on them. The Ugga-Bugga theme is, you guessed it, bugs. The Mega machine requires a $3.00 deposit to play. The theme of this slot machine is simply money.

The first theme that I found is the Ancient Egypt theme. It is noted that these are not all “good” machines. Descriptions of Egyptian styled objects and various animals cover these machines. Pharaohs and tomb raiders also cover some of the things slot machines. Most Egyptian themes revolve around the book of Ra, at the Nile, or Cleopatra.

Viking/Norse Mythology slots offer “Vikings go wild” slot this is one of the flagship slots games. There are quite a few Viking/Norse themes games out there. Here are a few: Thunderstruck II is a great Viking slot with an exciting storyline and a good RTP. Released in 2009, this game offers a ton of free spins. The “Hall of the Gods” is another great Viking/Norse slot with a chance to win a life-changing jackpot. Another slot that has a lot of people’s attention is “Thor: The Mighty Avenger”. On this slot, you can win up to $5000.00 in one single spin or play for the big jackpot. “Viking Gods: Thor Loki” figures as another with great graphics and colour. This game also has a 96.8% RTP. These games have proved very popular over the years and with tv shows, movies and now an assassins creed game revolving around Vikings, this theme looks like it will be around for a long time.

Horror Slots is another theme that has caught fire lately. Blood Suckers is a horror franchise theme divided into two parts. The slot features a standard five-reel layout with 25 pay lines. A Nightmare on Elm Street is a great slot based on Freddie Kruger’s story. This is a game that gives a warning about the graphic nature of its content. The RTP for this game is 94.5%. The Wolf’s Bane was released in 2019. This game has great sound effects. It is advisable to use headphones or speakers to enhance sound. This helps with focus. There are plenty of multipliers and free spins during gameplay.

The history of oriental slots is paved with scenes of imperial China, Geisha, and modern Asian landscapes. Most themes are centred on pictures from the Far East. This doesn’t mean you see these beautiful scenes and themes if you visit casinos from that part of the world. It just means we Westerners can certainly appreciate the far eastern culture. To put it mildly, if you’re into Asian themes, you will find no shortage of them on slot machines.

Movie Slots are slots that feature movie themes and you will find no shortage when searching. On google, “The Gladiator” with Russell Crowe was one of the top movie themes for slots last year. Other big hits were “Superman I and II” with the other marvel slots following closely behind.

The top adventure slot listed is Gonzo’s quest which uses cascading symbols instead of traditional spinning wheels for the slots. On Gonzo’s quest, you get increased multipliers with this cascading feature. This makes this slot machine very popular for gamblers. Avalon II is another adventure slot machine that makes the list. This slot features stunning graphics and audio. It also features 5 reels and 243 ways to win. The game also has a “merlin feature” where the wizard appears randomly appear on any spin and awards a cash prize or multiplier.

Overall, several themes became popular in 2020. I listed the main ones above. One of the most popular games of all time is Aliens and Robots with 243 ways to win, great bonus rounds and good theme action. This game came from the people at Betsoft and is still a favourite.
