Yggdrasil

Yggdrasil's games are often easiest to recognise through a character or a recurring feature: a Viking gathering rage, a raptor building a multiplier, or a reel that behaves differently from the others. Those details give the studio a more useful identity than a broad description such as fantasy slots. Its catalogue includes individual games, linked series and releases built around named mechanics. Knowing which of these you are looking at helps you distinguish a familiar theme from a familiar set of rules.

This page brings together the developer's background, examples from its games and the casinos in our review collection that record Yggdrasil in their provider inventories. The casino entries are a starting point for comparing operators. Each has a review link alongside a separate link to the casino, so you can read about account and payment conditions before deciding whether an operator is relevant to you.

A supplier founded in 2013

Yggdrasil was founded in 2013. The company subsequently developed both a portfolio of its own releases and a business supporting games from other studios. Its tenth anniversary in 2023 provides a useful point in that history, but an anniversary is not the release date of every game that carries the brand. The original Vikings Go Berzerk, for example, predates several later additions to the same family.

The business has offices in Malta and Kraków. These addresses describe the organisation behind the games; they do not tell you where a casino account is held. A software company can supply a title to several operators without controlling those operators' deposits, withdrawals or customer checks. When you compare casinos below, keep the provider's identity separate from the legal entity named in an operator's terms.

The same distinction matters when reading older coverage. A historical distribution agreement establishes that a relationship existed at that time. It does not prove that every title is available at that operator today, in every country or on every account. A useful comparison needs the current casino inventory as well as the right game and studio credit.

Who made the game you are looking at?

Yggdrasil appears in more than one role. It develops games internally and also offers technology and publishing support to independent studios. The YGG Masters catalogue identifies separate developers, including names such as 4ThePlayer, Avatar UX, HungryBear and Peter and Sons. A game distributed through that collection can retain its own studio's creative identity and design choices.

For a player, the practical step is to read the individual game's credit. A shared platform does not make two studios' games interchangeable. Artwork, win evaluation and feature pacing can differ even when the titles arrive through the same distribution channel. The studio name and the game name together are a more precise identifier than a publisher logo alone.

This also explains why adding every related studio's catalogue into one total can be misleading. A count of Yggdrasil's own games, a count including partner releases and the number installed at one casino answer different questions. Our information table leaves Total games empty rather than combining unlike figures into an apparent global total. The list of 95 matching casinos is a separate count drawn from our own review collection.

Vikings Go Berzerk and the role of its characters

Vikings Go Berzerk was released on 23 November 2016. Its five reels and four rows use 25 paylines, while four Viking characters connect the base game to its free spins. A win involving a Viking increases that character's rage meter. Filling the meter triggers free spins with that Viking in Berzerk Mode, where the character defeats the siren and becomes a sticky wild for the remaining feature.

The characters therefore do more than decorate the reels. They identify separate progress meters and different states within the feature. A player seeing the same Viking in a promotional picture and in the game can connect the artwork with a specific mechanic. Ragnarök free spins put all four Vikings into Berzerk Mode, and treasure chests add another layer to the bonus.

The published game page lists a 96.1% return configuration and medium-high volatility. Those figures describe the named product configuration, rather than a promise about a session. Check the version loaded by your casino before relying on a return figure from a general product description. A familiar title or character is not sufficient evidence that every setting is identical.

Reloaded is a separate release

Vikings Go Berzerk Reloaded followed on 30 September 2021. It keeps the series' recognisable warriors and sticky-wild idea while adding its own rules. Wilds in free spins can carry multipliers up to 8x, and the Ragnarok Spin can turn high-paying symbols into wilds. The game also includes a bonus purchase option and a feature gamble, where those options are offered in the applicable configuration.

These additions make the full title important. Searching only for Vikings can bring up the original game, Reloaded and other sequels. They share a visual family, but a description of one should not be used as the instruction sheet for another. Reloaded's product page advertises a 96% configuration and 25 lines; that does not replace the original game's published details.

Before opening a feature purchase or a gamble option, read its own confirmation and rules. The presence of a related mechanic elsewhere in the series does not establish its cost or result here. Choosing a game by its full name first makes those comparisons much clearer.

The Vikings in Las Vegas

Vikings Go To Vegas Wild Fight takes the established warriors into a different setting. The official release announcement dated 12 June 2025 places them among the lights of Las Vegas while keeping fighting, rage collection and sticky wilds central to the game. During free spins, a victorious Wild Fight turns a Viking into a sticky wild. Ragnarök puts the warriors into Berzerk Mode for their fights.

The change of setting is a good example of a series carrying its identity into new artwork without simply reusing an old background. The announcement lists 94.0% and 90.5% RTP options according to market configuration. Even within one named release, the active version therefore matters. A screenshot of its characters can identify the game, but cannot establish which mathematical setting a casino is running.

If you enjoy the series' presentation, compare the actual bonus rules rather than expecting each sequel to reproduce the first game. The recurring cast is a guide to the family. It is not a substitute for the information panel.

Raptor and a different kind of progression

Raptor 2, released on 15 January 2026, shows another side of the catalogue. The prehistoric theme accompanies DoubleMax mechanics rather than the Vikings' character-specific rage system. Its product page describes a five-reel, three-row game with free spins, wilds, a bonus purchase feature and expanding reels. These are features of that release, not a list that applies to every Yggdrasil slot.

The published RTP options are 97%, 96%, 94% and 90.5%. That range is particularly useful when explaining why a studio-wide return figure would be unhelpful. Looking up the highest available setting does not establish that your casino has selected it. Read the percentage in the version you are actually offered, together with its bet settings and feature information.

A multiplier-focused game can also feel different from a collection feature even when both build anticipation. Watch what advances the feature, what resets it and which wins receive the multiplier. The name DoubleMax helps identify the mechanic, but the individual rules define its operation in Raptor 2.

Mechanics beyond the artwork

Yggdrasil groups several of its feature concepts under the name Game Engagement Mechanics, or GEMs. These labels help connect related ideas across different themes. They do not establish that every title has the same win frequency, volatility, maximum payout or return. A name on the opening screen should lead you to the rules of that game, rather than to assumptions based on another release.

Starfire Fortunes TopHit provides a concrete example. Its additional reel sits above the main game. Fully visible high-paying symbols can become wilds and turn matching symbols on the reels into wilds, while a nudge feature can bring partially visible symbols into view. The design changes where a player needs to look and how the special reel interacts with the main grid.

This is a different idea from simply adding another ordinary reel to a payline game. It is also different from the Vikings' rage meters. Comparing the trigger and the effect is more informative than describing both as bonus features. Two games can use similar language while asking you to follow very different events on screen.

A changing theme does not always mean a changing rule set

Seasons offers another useful contrast. Its setting moves through different seasons, and the game can move to the next season after ten spins have been played in one of them. The visible change is part of the game's presentation and sequence. It should not be interpreted as evidence that the next season is due to pay a particular amount.

The title uses matching symbols on paylines, so its visual transitions need to be understood alongside the ordinary win evaluation. A player may remember a colour palette or seasonal scene particularly well, but that memory does not determine the next outcome. Read what the transition actually changes in the rules instead of assigning a financial meaning to the animation.

Across the catalogue, this is a useful way to separate atmosphere from mechanics. A character, a setting or a familiar sound can identify a game quickly. The paytable explains which symbols win and what any collected progress does. Both belong in a game description, but they answer different questions.

Development tools and casino promotions

Yggdrasil's business also includes development products. Game in a Box brings game logic, mathematical configuration, artwork, sound and testing into a connected development environment. Studio in a Box adds infrastructure intended to help a studio operate, while Forge provides development tools. These are products for creating and delivering games; they are not player account services.

BOOST is another separate part of the offering. It supports promotional formats such as free spins, tournaments, missions and prize drops. A casino can use those tools within an offer, but the existence of BOOST does not establish the terms of a promotion on an individual account. The operator's offer still needs a named game, qualifying conditions and a clear explanation of any reward.

For example, a game's built-in free spins round and promotional free spins awarded by a casino are different things. The first belongs to the game rules. The second belongs to an operator's campaign. A casino's wagering requirement should not be described as a permanent property of the software developer or of every game it supplies.

What a supplier licence tells you

The information table identifies Yggdrasil Gaming Ltd's Malta supplier licence and a separately verified British remote licence for Yggdrasil Gaming (Gibraltar) Limited. These are different legal entities and permissions. The British register lists account 45735 with active remote licence 045735-R-323978-011. Matching the entity and account is more reliable than copying an old licence suffix from an earlier description.

The market table records supplier licensing jurisdictions listed by the company. A software or hosting permission is not a universal authorisation for a player to open an account. The casino must operate under the rules applicable to its business and your location. A game can therefore be licensed for supply while a particular operator still excludes your country or does not offer that title there.

When checking a casino, use its own operator name and terms. The developer's licence is relevant to the supply of games. It cannot answer whether a payment method is available to you, whether an account needs additional verification or which dispute route applies to a withdrawal.

Why casino libraries differ

An operator rarely offers a simple mirror of a developer's public catalogue. Its library can depend on distribution agreements, market approvals, selected game versions and the way the lobby groups providers. Some casinos place a developer's own games and partner titles under different filters. Others show a publisher name prominently while retaining a separate studio credit inside the game.

That makes a provider listing useful, but limited evidence. The 95 casinos below record Yggdrasil in their provider inventories. This does not mean that every one currently offers all the games discussed here. If one particular title matters to you, search for its full name in the operator's lobby before making any account or deposit decision.

The distinction between a catalogue total and an operator's installed collection is equally important. An announcement about a deployment of 106 titles in Germany describes that deployment. It does not establish the size of Yggdrasil's complete worldwide library. Counting games responsibly means deciding first whether the number refers to original releases, partner content, variants or one casino's available collection.

Reading return and volatility information

RTP is a theoretical long-run proportion associated with a particular mathematical configuration. It does not describe what one player will receive over a short visit. Volatility describes the spread of possible results in a different way. A title with a higher published return can still produce an uneven session, and a bonus can arrive without producing a large win.

Keep those ideas separate when comparing games. The return percentage, feature structure and stake are different inputs. A maximum multiplier describes a possible outcome subject to the rules, not a likely result. A growing meter or a dramatic animation does not make that maximum imminent. The information panel should explain how an advertised feature works and the limits attached to it.

Changing the stake also deserves attention. Some features depend on a selected mode or option, and an optional purchase can be a separate charge. Before accepting one, identify the total amount displayed by the game. Do not assume that a price or rule from a related title transfers to the current release simply because the characters look familiar.

Using the games on a phone

The Vikings product pages identify mobile support, but the operator supplies the route by which you open a game. On a smaller display, make sure you can read the current stake, open the information menu and distinguish an ordinary spin from an optional purchase or gamble. If controls are obscured or the layout is cut off, resolving that display problem comes before making a selection.

A game session and a casino login are also separate layers. If a game appears to stop responding, check the account or round history before repeating an action involving money. A slow animation is not enough to establish that a round failed. The operator's support team needs the game name and relevant round information to investigate a disputed result.

Visual familiarity can help navigation, especially in a series with recurring characters. It should not take the place of reading the current interface. A sequel may move a feature control, use a different stake selector or offer a different combination of options from the game you remember.

Comparing the casinos on this page

Start with the conditions that belong to the operator: accepted countries, account verification, available currencies, payment methods and withdrawal rules. Then check whether the actual game you want is present. This order makes the provider list a useful filter without letting a familiar studio logo stand in for a review of the casino itself.

Use Read review to examine the recorded operator information and the separate Visit Casino link when you want to inspect its current offering. A provider match establishes why the casino appears in this collection. It does not make the casinos equivalent or guarantee that an offer applies to your account. Where a promotion is relevant, read its conditions separately from the slot's own rules.

Yggdrasil's strongest identifying details are its actual games: the Vikings' separate rage meters, a Raptor multiplier feature or the interaction between TopHit's upper reel and the main grid. Starting with those concrete differences makes the catalogue easier to understand. Combining that understanding with the operator information below gives you a clearer basis for comparison than a theme, a headline payout or a supplier name alone.
