1. Tesla: Spark of Genius Slot – GameArt – (Early 20th century inventor/engineer)

Tesla Spark of Genius - GameArt

Nikola Tesla is one of the most famous inventors and electrical engineers of all time. Worldwide, he was responsible for around 300 patents, and is best known today for his advances in wireless technology, and his name lives on as a measurement of magnetic flux density. In recent years, he has become popularized as an example of a genius whose work was misunderstood and largely overlooked during his lifetime.

Tesla: Spark of Genius tries to honour Tesla’s legacy through a slot machine that offers the popular 243 ways format. If you hit three or more AC Motor symbols, you’ll trigger a bonus round in which you get to pick your feature, choosing from differing numbers of free games and bonus multipliers. Light bulbs can earn you additional bonus wins, while you can also retrigger the free spins round for even more opportunities to win big.

2. Moby Dick Online Slot – Microgaming – (Book by Herman Melville)

Moby Dick Online - Microgaming

Herman Melville’s Moby Dick is an 1851 novel that tells the tale of Ahab, a captain who is out for revenge against Moby Dick, a while that previously bit off his leg. While Moby Dick was largely panned at the time of its release, later authors and critics would go on to praise it as one of the Great American Novels, as well as perhaps the best book about life on the sea ever written.

The Moby Dick slot that can be found at Microgaming casinos features imagery straight out of the novel. For instance, you can hit a ship’s wheel as a wild symbol, or find Moby Dick’s mouth as the scatter. Hit four of those mouths and you’ll earn 10 or more free spins, which can also be retriggered. Should you hit a winning combination with at least three scatters on the screen, you’ll get a bonus spin in which all the winning symbols are held in place for guaranteed wins and potentially new rewards.

3. Street Fighter II: The World Warrior Slot – NetEnt (Video game)

Street Fighter II The World Warrior - NetEnt

If you enjoy arcade fighting games, you’ll be intimately familiar with the Street Fighter series. However, those new to the Capcom series might not know that the original game was only a modest success. It was the sequel – Street Fighter II – that set the world ablaze in 1991. With eight playable characters and four additional bosses (all of whom were playable in later editions), Street Fighter II set the standard for what competitive fighting games would look like for the next 30 years.

NetEnt has honoured this legacy with its Street Fighter II game, one of the best slots we’ve seen incorporate a fighting game’s unique characteristics. Each time you play, you’ll pick from one of these eight main characters:

  • Ryu
  • Ken
  • Blanka
  • Chun-Li
  • Zangief
  • Ken
  • Guile
  • Dhalsim

Character selection will impact how the game plays and how volatile your payouts will be. Normal wins happen through the cluster pays mechanic, but you can also trigger bonus rounds based on special features from the game itself.

4. Jimi Hendrix Online Slot – NetEnt – (Rock guitar legend)

Jimi Hendrix Online Slot - NetEnt

Jimi Hendrix may have only enjoyed a short time in the spotlight during his life, but he is still considered one of the most influential musicians of the 20th century. Hendrix is widely regarded as one of the best electric guitarists ever, and headlined Woodstock in 1969. Many of he biggest hits came on “Electric Ladyland,” his final studio album. He died at age 27 in London due to an accidental death from asphyxia.

In the Jimi Hendrix online slot, you’ll celebrate his legendary career over five reels and 20 paylines of action. The game starts with your standard goal of matching symbols to score wins, but there are a number of features that make this game a lot more interesting. If you hit three or more scatters, for instance, you access a Pick and Click feature that can lead you into three different free spins games or an instant coin win.

5. Ronnie O’Sullivan: Sporting Legends – Playtech – (Snooker legend)

Ronnie O’Sullivan Sporting Legends - Playtech

If you aren’t a fan of snooker, you may never have heard of Ronnie O’Sullivan. Not only is he the current No. 1 player in the world, but he’s widely considered one of the greatest players in the history of the sport. O’Sullivan has won seven World Snooker Championships, eight Masters titles, and eight UK Championships, and holds the record for most total career ranking titles (41).

With that kind of legacy, it’s no surprise that Playtech has made a popular slot based on the snooker legend. Many of the game’s features are based on O’Sullivan’s exploits, from a 147 Maximum Break free games round to a Championship Bonus pick ‘em feature that sees you attempt to navigate a tournament all the way through the finals in order to collect prizes. With a wide range of coin sizes and lots of fun symbols and bonuses, this is a must play for any O’Sullivan fan.

6. The Legend of Shangri-La: Cluster Pays – NetEnt – (Book by James Hilton)

The Legend of Shangri-La Cluster Pays - NetEnt

In 1933, English writer James Hilton released his book Lost Horizon. While the novel itself was a massive hit, it is best known today for introducing the concept of Shangri-La: a fictional, utopian valley located somewhere in Tibet’s Kunlun Mountains. The mythical location has since been referenced in popular media again and again over the last 90 years, and has also inspired other mythical locations in fiction.

Shangri-La first appeared on the big screen in the 1937 film adaptation of Lost Horizon, which was directed by Frank Capra.

The Legend of Shangri-La utilizes the Cluster Pays system, which ignores the traditional paylines in exchange for a 5×6 grid. The goal is to make “clusters” of adjoining symbols; the bigger the cluster, the more you win. You’ll also want to be on the lookout for respins, a free spins game, and substitution symbols, which will instantly turn into whatever symbol will win you the most money.

7. Andre the Giant – NextGen Gaming – (70s/80s pro wrestler)

Andre the Giant - NextGen Gaming

Known as “the 8th Wonder of the World,” Andre the Giant – born Andre Rene Roussimoff – was one of the best-known professional wrestlers in the world from the 1970s through the 1980s. In later years, he would famously feud with Hulk Hogan, with the two headlining WrestleMania III in 1987. Andre also gained widespread fame for his role as Fezzik the giant in the film The Princess Bride, which was released that same year.

In the Andre the Giant slot machine, you can relive this massive legend’s career with a game filled with professional wrestling symbols like championship belts and referees, while Andre himself acts as the wild. Like most good slots, you’ll be able to collect free games, this time in the form of the Battle Bout bonus that triggers 10 free spins. There’s also the ability to retrigger this bonus round by finding Andre’s special moves hidden on the reels during the extra round.

8. Elvis: The King Lives – WMS – (Music legend)

Elvis The King Lives - WMS

Few artists have taken the world by storm like Elvis Presley. Known as the King of Rock and Roll, Elvis hit No. 1 on the charts in 1956 with “Heartbreak Hotel,” and would go on to become the best-selling soli artist of all-time by selling around 400 million records worldwide. Presley also made waves in the film industry, appearing in famous films like Jailhouse Rock and Viva Las Vegas. Elvis has even posthumously won the Presidential Medal of Freedom in the United States.

Elvis: The King Lives is a loving tribute to the musician from slots creator WMS. There’s a unique setup here, with one 2×2 reel section and another that runs 3×6, which leads to some unusual combinations that take a few spins to get used to. Once you do, however, you’ll have fun collecting free spins and triggering the Jukebox Bonus, in which you’ll collect rewards including multipliers and free spins by spinning up one of four classic Elvis hits.

9. Frankie Dettori’s Magic Seven – Playtech – (Italian jockey)

Frankie Dettoris Magic Seven - Playtech

The legendary Frankie Dettori is widely regarded as one of the greatest jockeys in the history of British horse racing. Dettori rode for more than 35 years, winning hundreds of top-tier racing and being named the British flat racing Champion Jockey on three occasions. Perhaps his best-known achievement was riding the winners of all seven races on the British Festival of Racing Day in 1996 – the titular “Magic Seven” of this game.

With such a wealth of success to draw on, Playtech had no trouble building an engaging slot around Dettori’s accomplishments. The game has a strong racing flavour, including numerous clips from the jockey’s illustrious career. The Free Games Race sees you choose one of three horses, at which point you’ll root for your pick to finish as high as possible in the race to earn you more free spins. There’s also a Magic Seven bonus that sees you picking sections of a racetrack to unlock various prizes.

10. Beowulf Slot – Pragmatic Play (8th-11th Century Old English poem)

Beowulf Slot - Pragmatic Play

Few stories have stood the test of time as well as Beowulf. This Old English epic poem was written sometime between 700-1000 AD, meaning that this is a story that has been retold for over a millennium. The tale of Beowulf follows our hero as he slays the monster Grendel, defeats Grendel’s mother, and finally kills a dragon before being slain.

There have been numerous adaptations of Beowulf throughout history, including a 2007 feature film that stars Ray Winstone, Anthony Hopkins, John Malkovich, and Robin Wright Penn.

The legend comes to life again in the Beowulf online slot machine, which can be found at Pragmatic Play casinos. This game offers epic prizes if you can match five-of-a-kind, including a 2,500-credit win for hitting five of Beowulf himself. You can also use the hero to trigger a respin feature that adds more Beowulf icons to the screen. There’s also the classic free spins bonus, where you can earn up to 20 addition spins and win multipliers as high as 25x.
