Yggdrasil slots are widely considered to be some of the most exciting and potentially rewarding slots on the market – featuring unique elements of slot feature innovation and constant evolution. Some of the hottest slot mechanics from Yggdrasil, include Splitz and MultiMAX. But for many, the Gigablox feature is their favourite!


Yggdrasil is one of the most innovative studios, when it comes to pushing online slots to new levels of excitement, variety and win potential. One key aspect of the studio, is the desire to meet the true demands of today’s cutting-edge player – and that means constant evolution of themes and slot mechanics such as Gigablox. Jonas Strandman, Senior Product Strategist at Yggdrasil, revealed the ethos behind the Gigablox concept, when Lucky Neko Gigablox was launched in 2020:

“Every spin of Lucky Neko Gigablox™ is a joy to play. With the Gigablox reels the next big win is just around the corner and the free spins offer some serious win potential from time to time. We continue to drive innovation throughout the industry and can’t wait to see how the Gigablox™ mechanic is received by our fans across the globe.”

Simply put, the Gigablox enables dynamic reels to spawn gigantic blocks up to 6×6 stacked. The net result are spin sessions that are innovative and can create truly massive wins for lucky players.

The basics of winning combinations on slot machines, will always remain the same – random luck! Typically just spin-in 3-5 of the same symbol on a payline, and pocket the payout.

However, an increasing number of online slot games, trigger bonuses after every winning spin – such as cascading symbols, or extra infinity reels. In the case of the Gigablox mechanic, Yggdrasil came-up with the idea of winning combinations, triggering synched reels with giant blocks (and the ‘Gigablox’ was christened!).

So let’s see what this really means to us slot players, when we play Gigablox games like Lucky Neko – just how much power can we gain in terms of winning potential?

To trigger the Gigablox feature, you just need to spin a winning combination on the slot you’re playing. Every win creates one (or more) ‘Synched reel’, which respins with a Gigablox. Base game Gigablox can vary in size, between 2×3, 3×3 and 4×4 regular symbols – but up to 6×6 in some bonus modes.

  • Spin a winning combination
  • Gigablox is activated to spin with a synched reel
  • A 2×2, 3×3, 4×4 or even up to 6×6 Gigablox is created (in some free spin modes)
  • You can trigger one or more synched reels per winning spin


The Yggdrasil team spent months developing the Gigablox mechanic, but one it was ready, the games being developed in the background were soon ready to hit the market. The first two Gigablox games, Lucky Neko Gigablox and Hades Gigablox, were released in 2020 – with Atlantean Gigarise released in 2021. This completes the Gigablox games at the time of writing – but expect to see new games with the mechanic in the near future. Here’s more insight into the current the current Gigablox portfolio:

Lucky Neko BackgroundLucky Neko Gigablox slot: As the first game in the Gigablox portfolio, released in 2020, Lucky Neko slot needed to make a big impression – and it’s done just that! Firstly this Asian style video slot is seriously quirky and cool – it’s a fun spinner that can be played with low level spins from just €0.08. However, this Gigablox classic also has plenty of power for hardcore players – the betting level can be progressively increased all the way to the unlikely level for most players, of €100. The expanding Gigablox and synched reels combine to create a huge number of ways to win, with the max win set at 6953x the triggering bet (€556 – €695,300 depending on the bet level).

Hades source desc imageHades Gigablox: As the second game released in the Gigablox family, in October 2020, Hades Gigablox had a lot to live-up to. Fortunately, with a totally different look and theme that takes players into the mysterious realm of King Hades, this game instantly gained a ton of fans. The Gigablox help to trigger epic fights between Hades and monsters, in an attempt to gain you nice wins! There are x10 Multipliers on offer if you get really lucky, and a max 11,129x top win is achievable – up to €1,112,900 depending on the bet selected (€0.10 – €100). See the full Hades Gigablox review…

Atlantean Gigarise: This is the newest Gigablox game playable at the moment, released in 2021. With a magical aquatic theme, the Gigablox get to work on  slotscape that can create  32,768 ways to win and a jackpot surprise for lucky players! The max win of 5235x the triggering bet, can deliver up to €209,400 depending on the triggering bet level. See the full Atlantean Gigarise review…

Atlantean Gigarise


Playing Gigablox slots is super easy and doesn’t need any skill – it’s all about setting your bet to the right level and letting the slot mechanics do the leg work.

1. Pick a Gigablox slot (Lucky Neko, Hades, Atlantean Gigarise)

2. Select your coin/total bet size

3. Click spin

4. Wait for the Synched Reels & Gigablox to activate

If you’re seeking strategy tips, then then best advice is to select a spin size that you’re comfortable with, alongside a session limit. Gigablox games can be volatile, so you might get the best value and chance of triggering the best Gigablox and slot features, by using a bet size that supports 100-200+ spins in a session.


Along with Gigablox, Yggdrasil’s Splitz and MultiMAX features, all provide different slot games, with something unique. Before looking at the differences between these features, it’s worth noting that all Yggdrasil video slots, typically have very similar and fair RTP levels – so there’s no long-term advantage of one type of slot feature, versus another!

The first difference is in the style of the mechanics and the impact on the flow of the gameplay. With Gigablox you get the giant symbols, with MultiMax games like MultiFLY you can get multipliers merging and multiplying to create amazing numbers of ways to win big, while Splitz in games like Temple Stacks, symbols are sharded to create payline numbers like 248,832.

All these mechanics give different visuals and work in their own way when it comes to volatility – but they all work to create the potential for boosting the number of ways to win and potentially payout magnitude.  You just need the luck to see them at full power! Ultimately, deciding which feature is better, is subjective – it’s all down to how much you enjoy games featuring Gigablox, versus Splitz and MultiMAX.


Like all Yggdrasil slots and slots on the YGS Masters network, slots featuring Gigablox feature fair RTP levels, meaning fair average returns to the pool of players who spin the games, in the long run. The Gigablox feature is designed to create the potential for lucky players to create some very powerful winning combination – which is why lucky synched reels can potentially take payout levels to jackpot style rewards!

If there’s a disadvantage to the Gigablox, then arguably it’s the fact that you can potentially hit some cold runs, or get unlucky when it comes to getting your fair share of the best Gigablox (missing out on the juicy x4 blocks for example). However, realistically, this is the volatile chance you take on all slots that have a potentially awesome upside. So if you play consistent sessions on Gigablox slots, using a stable spin size and good spin volume, you could find yourself on some of the game’s hot runs!

There’s also always the chance that you just don’t resonate with the themes of the current line-up of Gigablox slots. Although there’s already plenty of variety and new games planned for 2021 and beyond, it’s still all down to the style and themes of Yggdrasil slots you prefer.

The Evolution of Gigablox Games on YGS Masters Platform

If you think the current crop of Gigablox games are impressive – get ready to level-up again! Yggdrasil has announced its Gigablox mechanic is set to feature in games from studios on the YGS Masters network. Once such studio, is Reflex Gaming, who announced in February 2021 that they’d soon be creating games that incorporate the Gigablox™ mechanic, adding to their first release on the network, Moley Moolah:

Yggdrasil also commented on the development with Reflex, noting, “Our partnership with Reflex Gaming is going from strength-to-strength, and we are excited to see the upcoming titles they will deliver with the Gigablox™ mechanic to further fuel their success.”
