Yggdrasil Gaming is a studio that is always experimenting with new formats and game mechanics. Over the years, we’ve seen Yggdrasil introduce a number of interesting new gameplay features like Gigablox and Splitz. Now, Gigarise has been added into the mix which features expanding reels for more ways to win.

Theme and Graphics

Yggdrasil’s Atlantean Gigarise takes players on an underwater adventure to the lost world of Atlantis. The game features a dreamy blue backdrop with drowned ancient structures standing tall. Colourful coral sits at the front of the reels while fish swim across the screen and bubbles float up to the surface.

Overall, it’s a great-looking game with some beautiful details. Yggdrasil never really fails us in the design department, though.

RTP and Variance

The RTP (return to player) of Atlantean Gigarise is 96%. It’s also a lower variance online slot game, which you don’t tend to see very often in today’s gaming market.

How to Win

In Atlantean Gigarise, wins are created by landing thee or more matching symbols on adjacent reels from left to right. The game begins with 2520 ways to win, but you can increase the number of winning ways by landing trident symbols.

Every time a trident appears on a reel, it will expand upward by one symbol space. Over time, this gradually gives you more ways to win – up to a maximum of 32,768.

When you begin playing this slot, make sure your bet is at the correct level and one that you’re happy with using for a prolonged period. When you change your bet size, the reels will reset to 2520 winning ways if you start with a new wager.

Bonus Game

The bonus game in Atlantean Gigarise is triggered by expanding one reel to its full height. This is a Money Train-style bonus feature where you can collect prizes when symbols fall on the highlighted section of the screen.

During the bonus game, you get three lives and symbols can land that represent cash prizes, the free spins bonus or one of the jackpots on offer. There are six progressive jackpots available, seeding at the following amounts:

  • Forgotten: £40
  • Rare: £200
  • Mythical: £600
  • Ancient: £1,500
  • Legendary: £15,000
Max-win 4,370x

Top RTP 96%

Free Spins

Landing three or more scatters will trigger the free spins bonus. Here, all reels start at 3 symbols high; however, the Trident symbols land a lot more often here than they do in the base game which adds a bit more excitement.

There isn’t really anything special to the free spins bonus – but the plus side is that there are lots of free spins on offer. You can get 20, 40 or 80 initially and you can earn 5 extra free spins just by landing two scatters.

Overall Review

With more and more Megaways slot games being released every month, it’s nice to see something a little different. The expanding reels feature is always good fun, and gives players something interesting to look forward to as they spin the reels.

This is a pretty unique way for reel expansions to take place and, while it does take a while for the reels to grow, it keeps you on your toes. It’s a great mechanic, and we’d like to see it more in other Yggdrasil slots.

The bonus features are also pretty impressive. There are plenty on offer, although you can go quite a while without triggering one. You’d think that you’d land the Bonus Round before the free spins but the tridents are difficult to collect during the main game so this very well be the more elusive feature for you.

Overall, Yggdrasil has done an impressive job in creating a new game mechanic immersed in a vibrant theme. The rest of the gameplay offers an entertaining experience, as well, especially with the low/medium variance maths model.
