Yggdrasil Gaming Company Overview

Features of Yggdrasil Gaming

Distinctive Slots with Careful Attention to Detail

Yggdrasil puts considerable effort into the graphics, music and theme of each game.

The animations of characters and symbols are smooth, and many games include large, eye-catching animated sequences, such as the dancers in Brazil Bomba and the tiger characters in Time Travel Tigers.

The slots are designed mobile-first, and their high-resolution graphics run on both smartphones and desktop.

Slots with Original Features

Yggdrasil is best known for features in which you collect a set number of points or symbols to win free spins or a jackpot, as in Vikings go to Hell and Jackpot Raiders.

The company continues to release features it has developed in-house. One example is the Splitz™ mechanic in Temple Stacks: Splitz, which splits symbols to increase the number of ways to win.

Launch of the Yggdrasil Game Server (YGS) Masters Program

In March 2018, Yggdrasil Gaming announced Yggdrasil Game Server (YGS) Masters, an open software platform for independent developers. Independent developers benefit from Yggdrasil’s development resources and name recognition, while Yggdrasil expands its content.

Studios taking part in the YGS Masters program (now YGG Masters) include Rabcat, 4ThePlayer, Northern Lights, Fantasma Games, Dreamtech Gaming and AvatarUX, and three games have been released through it: Lilith’s Inferno, Nikola Tesla’s Incredible Machine and Niagara Falls.

Latest Yggdrasil Gaming Games

Book of Evil

Game

Book of Evil

Provider

Yggdrasil Gaming (developed by SpinOn)

RTP

94%

Bonus buy

Yes (100x)

Max win

5,000x

Book of Evil was developed by SpinOn, one of Yggdrasil Gaming’s partner studios, and is distributed by Yggdrasil Gaming. As in other “Book of” slots, one special symbol is chosen for free spins, and when it lands it expands to cover the whole reel and pays a special win. A five-of-a-kind win with the highest-paying symbol pays up to 5,000x.

Mystic Magic

Game

Mystic Magic

Provider

Yggdrasil Gaming (developed by Hungrybear)

RTP

94%

Bonus buy

No

Max win

6,814x

Mystic Magic is another slot from a Yggdrasil Gaming partner studio, in this case Hungrybear.

The game is built around powering up the free spins. Each test tube symbol that lands boosts the free spins, for example by adding spins or raising the multiplier. When the bonus symbols line up, free spins begin with whatever has been built up so far, so the longer it takes to reach the bonus round, the stronger the feature is when it starts.

Book Extreme

Game

Book Extreme

Provider

Yggdrasil Gaming (developed by AceRun)

RTP

94%

Bonus buy

No

Max win

10,092x

Book Extreme was also developed by a partner studio, AceRun.

As in Book of Evil, one special symbol pays a special win during free spins. Each time the free spins symbols land again during the feature, the number of special symbols increases to two, then three, and additional free spins are awarded.

Yggdrasil Gaming Table Games

The RTP figures below are theoretical values for each type of bet and do not include the random multiplier draws. The figure depends on the bet, and the RTP of the same game may also vary with the casino’s settings, so check the actual figure on the game’s info screen at the casino where you play.

Roulette Evolution VIP

Game

Roulette Evolution VIP

Provider

Yggdrasil Gaming

RTP

97.30%

Max win

35 to 1 (a $10 bet wins $350, or $360 including the stake)

Roulette Evolution VIP is a straightforward RNG roulette game. As the VIP name suggests, it accepts large bets, but the betting range is wide enough to suit players from beginners to high rollers.

The game also lets you save your bets and set your own limits on playing time and bet amounts. A standard version, Roulette Evolution, has the same features with lower minimum and maximum bets, so players who want to start with small stakes may prefer that version.

Golden Chip Roulette

Game

Golden Chip Roulette

Provider

Yggdrasil Gaming

RTP

97.30%

Max win

500x (the top multiplier in the multiplier draw)

Golden Chip Roulette is an RNG roulette game with a multiplier draw. On a straight-up bet (a bet on a single number), a multiplier draw takes place before the ball lands, and a multiplier of 10x to 500x is assigned to the number you bet on. You can choose between the standard payout, which returns 36 times your stake, and playing for the multiplier draw.

Yggdrasil Gaming Safety and Reliability

Founded in 2013, Yggdrasil Gaming is a provider that operates under several licenses and is audited by independent testing labs.

Based in Malta, Yggdrasil Gaming holds licenses from 10 jurisdictions.

Holding a license does not in itself guarantee safety, but a license involves not only a review when it is granted but also ongoing supervision by the licensing authority. Of the regulators that license Yggdrasil, the Malta Gaming Authority (MGA) is known for particularly strict reviews and oversight.

The company has also won awards at industry events such as the EGR Awards and the International Gaming Awards.

Testing by Independent Labs

Beyond its licenses, Yggdrasil Gaming is audited regularly by the independent testing labs GLI (Gaming Laboratories International) and eCOGRA, and the random number generator (RNG) that produces slot results is tested as well. These checks make it effectively impossible for the operator to manipulate results.

What to Watch Out for with Yggdrasil Gaming

Some Games May Not Show Up in a Search for Yggdrasil

In addition to its in-house games, Yggdrasil Gaming releases games made by partner studios such as ReelPlay, SpinOn, Hungrybear and AceRun. Some casinos, however, list these games under the studio that developed them rather than under Yggdrasil Gaming.

If you want to play Book of Evil, for example, you may need to search for SpinOn rather than Yggdrasil to find it.

Some Games May Not Be Playable with Casino Bonuses

In this section, “casino bonus” refers to a deposit bonus, that is, bonus funds credited when you make a deposit. Many Yggdrasil Gaming games include a feature in which you collect in-game points to earn free spins.

Many casinos exclude these games from bonus play because a player could collect in-game points with bonus funds and then, once the wagering requirements have been met, unlock the free spins with real money, effectively turning the bonus into cash.

Keep in mind that you may not be able to play Yggdrasil Gaming games with a bonus. Even when a game is not on the list of restricted games, some casinos prohibit collecting in-game points with bonus funds and then unlocking the free spins with real money, so always check the terms and conditions.

Summary: Yggdrasil Stands Out for Its Carefully Crafted Original Features

Yggdrasil Gaming is a provider with a large lineup of distinctive slots.

Its games are known for detailed graphics and sound and for features of the company’s own design. In recent years it has also released games from partner studios, which has increased the number of new titles.

Many Yggdrasil slots let you collect in-game points to earn free spins, so you build toward the feature gradually as you keep spinning. Whether collected points carry over depends on the game and the casino, so check the game’s info screen before you play.
