A short and quick history of Microgaming

Before we dive into the top 10 list let’s take a quick look at the history of Microgaming and why it is one of the best slot game providers in the world.

Before Microgaming focused on developing slot games they were actually the first company to provide an online casino site all the way back in 1994. Although there are other companies that claim they were first, most people consider Microgaming to be the true first.

Being the first on the market Microgaming continually developed more games and technologies to keep itself at the forefront of the online gambling market. In 1998, Microgaming reached another first and released a slot game called Cash Splash, the first slot game with a progressive jackpot.

In the early 2000s Microgaming also began to diversify its product portfolio and launched its own poker platform, the Microgaming Poker Network, and also developed bingo software.

In 2005, Microgaming also released their first co-branded game, using the Tomb Raider IP. It is now a common trend to create slot games using popular movies and other icons, but again, Microgaming was one of the first online slot providers to do so.

Microgaming is based on the Isle of Man and now they provide a complete portfolio of products: casino games, multi-player games, online poker, bingo, land-based slot machines, sportsbook, and live dealer games.

Microgaming has released over 850 casino games, including over 1,200 variants. And now let’s dive into that massive portfolio and give you the top 10 most popular Microgaming slots.

Most Popular Microgaming Slots

It is not an easy task to jump into Microgaming’s massive collection of slot games and trim it down to just 10 selections. As we have already mentioned above, we have put together this list based on a number of different criteria.  You will find that most of the top slots are video slot games, but there are also a few progressive jackpots and a few classic three-reel spinners as well.

Thunderstruck II

Thunderstruck 2 is a 5 reel, 3 row and 243 ways to win slot. The slot features a Norse mythology theme with a focus on the Norse God of Thunder (Thor). The bet levels range from 30c to $15 per spin. There are the usual technical features such as Auto Play (up to 100 auto-spins). There is also a Quick Spin option.

Thunderstruck 2 has 8 bonus features included in the slot. Some of these features include random wild reels, 4 free spins features based on Valkyrie, Loki, Odin and Thor a Wildstorm feature and the Great Hall of Spins. The max win per free spin is up to 8,000x your stake.

The best feature of the Loki Free Spins is the maximum win, which may be up to 8,000x on each free spin. The random Wildstorm function also pays out at the same level.

Thunderstruck 2 is a pretty old game, but it’s still one of the greatest online slots. The thunderstruck Wild Lightning slot came out earlier in 2021 as a result of its tremendous popularity.

Game of Thrones slot

There is two Game of Thrones slots, each with a 5-reels, one is a 15-payline version and the other is a 243 ways to win variant.

The stakes for both versions are as follows:

  • 15 payline version: 15c to $37.50
  • 243 ways to win version: 30c to $15

Both slot games have a Quick Spin mode and an Autoplay function (up to 100 spins).

The max possible win varies on the version and which free spin feature you play. The max possible win per spin is 20,250x stake in the Baratheon Free Spins feature.

Game of Thrones comes with 5 bonus features including a Scatter Bonus feature and the 4 free spins features based on the 4 main Houses of Westeros.

Each house has its own set of free spins, multiplier, and stack symbols.

  • Baratheon Free Spins: 8 free spins with a 5x multiplier. House Baratheon Sigil symbols stack 3 high.
  • Lannister Free Spins: 10 free spins with a 4x multiplier. House Lannister Sigil symbol stack 4 high.
  • Stark Free Spins: 14 free spins with a 3x multiplier. House Stark Sigil symbols stack 5 high.
  • Targaryen Free Spins: 18 free spins with a 2x multiplier. House Targaryen Sigil symbols stack 6 high.

The Baratheon Free Spins round is the most enjoyable, as each free spin may result in a 20,250x stake payout.

To be honest, you should go for the 243 ways to win version rather than the less attractive 15 payline variation. The greater potential rewards of the 243 ways to win edition (20,250x stake) are well worth the extra effort.

You will undoubtedly enjoy the Game of Thrones slot game if you are a fan of the TV series.

Break da Bank Again Megaways

  • Triceratops Free Spins: The player received 12 free spins, and on each spin a wild is added to the wild stack. If your free spin does not win any full stack of wilds remains in place. Partial stacks get nudged from Triceratops to fill the reel. Any remaining reels spin again. These spins are also stacked.
  • Dilophosaurus Free Spins: The Dilophosaurus appears randomly and turns symbols wild. These lock into position as long as they are part of a winning combination. The Dilophosaurus is stacked.

The Jurassic Park film became the most successful to that point, grossing over $1 billion worldwide. With so many accolades to its name, the Jurassic Park slot version has done justice. The remastered version retains all of the characters and settings from the film.

The bonus features keep things exciting. Due to the potential 6x multipliers, the bigger prizes should come from the Velociraptor and Brachiosaurus free spins. However, on any spin or free spin, players can get up to 6333x stake. It’s a solid game all across the board.

Because the Jurassic Park slot proved to be so popular, Microgaming struck another deal with Universal Studios and released the Jurassic World slot to coincide with that movie’s release. The Jurassic World slot has less bonus features but it has a max win potential of up to 14,166x stake.

Jackpot Bonus Game feature

Of course, the Jackpot Bonus Game feature’s main draw is the potential megabucks on offer. This round has a chance of happening on every spin. The better your chances, the greater your stake.

Once the bonus game triggers you can spin the Progressive Jackpot Wheel. At this point you can win one of four jackpots: the Mini, Minor, Major or Mega jackpot. Each jackpot has a guaranteed minimum amount:

  • Mini Jackpot: $10 minimum
  • Minor Jackpot: $100 minimum
  • Major Jackpot: $10,000 minimum
  • Mega Jackpot: $1 million minimum

The Mega Moolah slot even without the progressive jackpot would be quite appealing. This is due to the fact that each free spin may result in a payout of 1,955x the bet amount.

The original Mega Moolah slot game looks quite dated so Microgaming has released a number of variants throughout the years. It is important to note each of these games has the same mechanics as the original and the same jackpots. The only things which have been updated are the graphics and sounds.
