Game Engagement Mechanics

Our Game Engagement Mechanics, also known as GEMs, add a unique element to gameplay through different changes to the reels. They elevate games to something recognisable and enjoyable for Yggdrasil fans across the globe.

We now have ten GEMs in our offering: DoubleMax, DuoMax, FastPot5, GigaBlox, GigaRise, MultiMax, Splitz, TopHit, WildEnergy and Wild Fight. All of these bring something different to games, and have proven to be incredibly popular among our player base.

  • DoubleMax™

    DoubleMax is powering the success of our hugely popular Raptor DoubleMax. This amazing GEM doubles multipliers on each cascading win with no limit, revealing enormous win potential. The multiplier is usually a single, global multiplier.

    On the 3×5 reels, Raptor DoubleMax features a doubling multiplier, where every consecutive win doubles your multiplier, with no limit to its extent. Since multipliers double, they are increased exponentially (x1, x2, x4, x8, x16, x32, x64…) and they can easily go into the hundreds very quickly!

  • DuoMax™

    Traditionally, most slot games have one multiplier that increases with consecutive wins. However, we took this concept above and beyond and created DuoMax, which takes the traditional single multiplier and instead turns it into two separate multipliers.

    This gives the option to have reels pay from separate ways and therefore give more potential to a player to increase their wins by significant amounts.

    DuoMax powers our apocalyptic release Florageddon! DuoMax, where multipliers are placed on either side of the reels. Therefore, paylines do not only pay from the left side of the reels, but also from the right. With every winning combination, the unlimited multipliers keep increasing and are sustained during Free Spins!

  • FastPot5™

    FastPot5 games have five, quick hitting jackpots that are tied to and awarded by an event that requires 5 collections.

    The jackpot is an amount of money that increases by a small, predetermined contribution each time the game is played. When won it resets to the initial value. Big jackpot wins are always possible with FastPot5!

    Our Ancient Greece themed game Elysian Jackpots places one jackpot at the top of each reel, having a total of five. Each jackpot is unlocked during Free Spins, where players can collect respective gemstones to win the jackpot. Suspense is unlimited with FastPot5!

  • GigaBlox™

    GigaBlox is all about massively sized symbols dynamically appearing on the reels during every spin. From the first spin, it is super clear what the framework is about, as the reels sync up to form stacked blox of various sizes on different reels.

    For example, a spin could have three reels filled with stacks of 2×2 blox, and the next one could have two reels filled with stacks of 3×3 blox. Line up huge blox on the reels for massive wins!

    Lucky Neko GigaBlox features a free game with bigger reels where stacked GigaBlox can reach a whopping 6×6.

    Our second release builds off the first – introducing GigaBlox battles, a truly innovative gaming experience!

  • GigaRise™

    Will you rise up and create even more massive ways to win? GigaRise is all about building up those reels; special symbols landing in-game will increase the height of the reels they land on. The number of ways grows exponentially with each expansion!

    And what’s power without persistence? The height of any reel will persist between spins. When a reel reaches maximum height, an award event is granted, whether it be Free Spins or another round of the Bonus Game. After that, the reel’s height resets so players can GigaRise all over again! With its 5 progressive Jackpots, the first game using the GigaRise mechanics was Atlantean GigaRise.

  • MultiMax™

    MultiMax encompasses a framework of games that accumulate multipliers on the reels. After each win, all reels having at least 1 symbol contributing to the win have their corresponding multipliers applied to the win, essentially creating a win multiplier equal to the product of all activated reel multipliers.

    For example, a 4-of-a-kind win from left to right would have its win multiplied by the four activated multipliers on reels 1,2,3 and 4, excluding the 5th reel multiplier that was not activated by any winning symbol.

    In Multifly! MultiMax, our first MultiMax title, multipliers on each reel increase by one for every Wild that lands on the corresponding reel, including a random Wild that’s guaranteed to appear after each cascade. As long as the cascading continues, the reel multipliers will increase with each new Wild. All reel multipliers will reset to 1 at the start of a new bet. If 3 scatters land during the base game, the reel multipliers accumulated on the base game bet continue to increase in the free games with each Wild that lands, and do not reset until all free games and cascades have been played.

  • Splitz™

    Splitz is all about mystery symbols that split to give you more – more ways, extra scatters, longer lines, or bigger clusters.

    With Splitz, the goal is clear – land as many Splitz symbols and have them split as much as you can for big win potential.

    With all Splitz symbols transforming into the same symbol with each spin, players continuously get moments of excitement where if the right symbol is revealed from all those Splitz created, and big wins will follow!

    In our first released Splitz game, Temple Stacks, Splitz can split ways for over 200,000 ways to win, whereas Neon Rush offers up to 15-of-a-kind line wins and scatters that can split for awards up to 25,000x!

  • TopHit™

    The innovative TopHit mechanic places a separate horizontal reel at the top of the classic vertical reels, adding an extra exciting variable to gameplay. Landing symbols which fully occupy spaces on the TopHit reel influences the result of the actual gameplay, so the stakes are high with this GEM!

    In our first TopHit game Starfire Fortunes TopHit, the mechanic can contribute to scatter trigger or turn corresponding symbols into Wilds. Symbols that do not land fully on the TopHit reel may also be nudged to land fully, creating even bigger opportunities for astronomical wins!

  • WildEnergy™

    WildEnergy is a GEM which shakes up the concept of Wilds for more exciting gameplay.

    A WildEnergy Wild can land on screen with a number of lives associated with it. Lives are activated via a specific trigger, typically, when the symbol is part of a win. These Wilds turn sticky and trigger Respins for as long as there are more lives. Additional WildEnergy symbols can land on the screen during Respins, creating the possibility of an infinite number of wins!

    The elemental Ragnawolves WildEnergy is powered by this mechanic, and up to a whopping four lives can land with each WildEnergy symbol!

  • Wild Fight™

    Wild Fight is a special feature where each high paying symbol that lands on the reels has the chance to become Wild. Each high pay fights a character where it either wins or loses, and one of these results generally turns the high pay into a Wild. All outcomes are different for each symbol, and Wilds obtained through this feature may have some special features, such as a 100% chance of victory!

    Being one of our most innovative mechanics, Wild Fight is a special feature where each of the high paying symbols that lands on the reels has the chance to become Wild.

    The player sees a fight animation where each high pay fights a character, and either wins or loses. Usually, one of these outcomes causes the high pay to turn into a Wild, depending on the individual game’s narrative.

    The result is always a mystery, as all outcomes are individual for each and every symbol.

    Wild Fight can either be triggered randomly during the base game or when a certain condition is met, for example during the bonus round. All wins are evaluated once, after the fights take place.

    The Wilds obtained through the feature may have special attributes (e.g. ‘sticky’), and sometimes, there might be a 100% chance of victory during Wild Fight!
