Free spins on Yggdrasil slots are normally 10p stakes, so 50 spins are £5 of play and, at the 96%–96.8% RTPs in our checked data, return roughly £4.80 to £4.84 on average. Our partners' welcome spins aren't on Yggdrasil games, so here is how to value any that are, from Vikings Go Berzerk to Valley of the Gods. 18+, terms apply.
Six Yggdrasil slots in our checked data range from 96% to 96.8% RTP, a gap worth about 8p per 100 spins at 10p.
Max wins run from 4,110× (Jackpot Raiders, excluding jackpots) to 25,000× (Vikings Go Berzerk Reloaded), so volatility matters far more than RTP.
Wagering on £6 of spins winnings at 10x costs about £2.28 on average at 96.2% RTP; no-wagering spins avoid that cost.
PlayOJO's 80 no-wagering spins are on Big Bass Bonanza, and Coral and Ladbrokes name their own selected games, so none is a Yggdrasil offer.

Free spins on Yggdrasil slots in brief
When a UK casino hands out free spins on a Yggdrasil game, each spin is a fixed stake, typically 10p, played on your behalf. The value you can expect is spins × stake × RTP, and the value you can keep depends on wagering, caps and deadlines in the offer terms. Yggdrasil's slots in our checked data all sit between 96% and 96.8% RTP, so the maths is close to identical across the range; the experience is not, because volatility and max wins differ widely.
Being straight about availability: none of our five partner casinos gives its welcome spins on a Yggdrasil slot at the moment. PlayOJO's 80 spins are on Big Bass Bonanza, and Coral and Ladbrokes run their spins on games listed on each promotion page. You can browse every spins offer we cover on the free spins hub, and use the method below to value any Yggdrasil offer you find at another UK-licensed casino.
Yggdrasil: the studio behind the Vikings games and Valley of the Gods
Yggdrasil was founded in 2013 and has offices in San Ġiljan, Malta, and Kraków, Poland, with James Curwen as chief executive. It holds a Great Britain licence as a business-to-business remote casino supplier, alongside licences in Malta (MGA/B2B/230/2012), Gibraltar and the Isle of Man. Reference listings put its catalogue at about 190 games.
Alongside its own titles, Yggdrasil runs a partner programme called YGG Masters, through which smaller studios release games on its platform; its site lists 21 partners. That means some slots carrying Yggdrasil branding in a casino lobby were built by another team, so the help screen is the place to confirm who made a game and what its RTP setting is.

Yggdrasil slots for free spins: verified RTP, volatility and max win
These are the Yggdrasil games with checked specifications. Where a figure is missing, we couldn't verify it, and the game's help screen is the reliable place to look. Four of the six have their own free spins page on this site.
Holmes & the Stolen Stones has the highest RTP of the group at 96.8%, which puts it among the stronger games covered on our free spins on high RTP slots page. Vikings Go Berzerk Reloaded has by far the highest ceiling, at 25,000 times the stake.
What free spins on Yggdrasil slots are worth: the maths
Three numbers do the work. The spin count and the coin value give you the face value. The RTP turns that into a long-run average, which is the expected value of the spins before any terms are applied. Here is the calculation for the highest and lowest RTPs in the Yggdrasil range.

Even at 500 spins, the gap between the best and worst RTP in the range is only 40p. For practical purposes, the studio's games are interchangeable on average value, and an offer's terms (spin value, wagering and any cap) will move the real worth far more than the choice of Yggdrasil title. The method is set out step by step in our guide to the expected value of a casino bonus.
Jackpot Raiders vs Valley of the Gods: same spins, very different sessions
Put 50 casino spins at 10p on two Yggdrasil games and the averages are almost the same: about £4.82 on Jackpot Raiders (96.3%) and £4.81 on Valley of the Gods (96.2%). The likely shape of the result is not.
Advantages
Jackpot Raiders is low volatility, so wins tend to be smaller and more frequent.
Its 4,110× max win (excluding jackpots) caps a single 10p spin at about £411 before any jackpot.
A batch of spins is more likely to finish within a few pounds of the average.
Drawbacks
Valley of the Gods is high volatility, so many batches of 50 spins will return well under £4.81.
Its 5,800× max win means a 10p spin can reach £580, but such results are rare.
A casino cap on spins winnings bites harder here, because the value is concentrated in rare outcomes.
Yggdrasil's best-known run of games follows a crew of Vikings across several releases, and three of them are in our checked data. They share a 5 × 4 grid with 25 paylines, which makes them a neat comparison of how one studio tuned the same format over time.
Vikings Go Wild (August 2015): 96.3% RTP and low-to-medium volatility, the gentlest of the three. See Vikings Go Wild free spins.
Vikings Go Berzerk (November 2016): 96.1% RTP with medium–high volatility, so a wider range of results from the same number of spins.
Vikings Go Berzerk Reloaded (2021): 96% RTP and a 25,000× max win, which is £2,500 on a 10p spin. Its main feature, according to our checked data, is a free spins round in which Berzerk Vikings turn into sticky wilds.
If you like the theme more than the studio, our page on free spins on Viking slots also covers Viking-themed games from other developers, and the general Vikings free spins page looks at the theme across the market.
How Yggdrasil's own free spins rounds work
A casino promotion and a slot's bonus feature share the name free spins but are separate things. The promotion gives you stakes; the slot's free spins round is a feature you reach during play, normally by landing a set number of scatter or bonus symbols. A promotional spin can land that trigger like any other paid spin, and any winnings from the round then belong to your spins winnings under the offer terms.
Yggdrasil tends to build its rounds around a twist on the base game, such as symbols that stay in place or grids that grow, but the details change from title to title. Our checked data confirms the sticky-wild Vikings in Vikings Go Berzerk Reloaded and the 45-to-3,125-ways spread in Valley of the Gods. For trigger counts, the number of spins awarded and how retriggers work on any other title, read the game's help screen rather than a summary, since those are the rules that apply to your spins.
In Great Britain you can't pay to buy straight into a bonus round: feature buys aren't offered on slots supplied to British players. The round has to be reached in normal play.
Wagering on Yggdrasil free spins winnings under the 10x cap
Since 19 January 2026, a UK-licensed casino can't require more than 10 times the bonus in wagering, a change the Gambling Commission announced in its news on safer, simpler promotions (opens in a new tab). The cost of wagering is roughly the amount wagered multiplied by the house edge, so lower multiples leave more of your winnings intact.

Checklist for a free spins offer that lists Yggdrasil games
Work down this list in order before depositing. Each step answers a question that changes the value or decides whether you get the spins at all. Our casino bonus checklist applies the same approach to every bonus type.
Check the Gambling Commission licence of the casino, not just the studio.
Find the significant terms box and confirm the named Yggdrasil game or games.
Note the spin value and work out the face value (spins × stake).
Look for the qualifying step: a minimum deposit, a minimum bet on slots, or both.
Check excluded payment methods; e-wallets and prepaid cards are common exclusions.
Read the claim window and how long the spins stay valid once credited.
Check whether winnings are cash or bonus funds, and any wagering multiple.
Look for a max cash-out or winnings cap, especially on high-volatility titles.

Jackpot Raiders and using free spins on jackpot games
Jackpot Raiders adds jackpots on top of its regular paytable, which is why its 4,110× max win is quoted excluding jackpots. With a casino free spin, two questions decide whether a jackpot is even possible: whether the jackpot can be won at the promotional stake, and whether the offer's terms cap free spins winnings below the jackpot amount. Both answers live in the game's help screen and the promotion's terms.
As a general rule, casinos rarely put welcome spins on jackpot games, and when they do, a winnings cap may apply. Our page on free spins on jackpot slots explains the common restrictions.
Using Yggdrasil free spins with a limit in mind
Free spins don't make gambling cheaper over time, and the house edge applies to every promotional spin just as it does to your own money. Treat the spins as a sample of a game and decide beforehand whether you'll keep playing once they're used. Deposit limits, time-outs and reality checks are available at every UK casino; see how to set deposit limits. GAMSTOP (opens in a new tab) lets you self-exclude from all GB-licensed gambling sites at once, and the National Gambling Helpline is free and open 24/7 on 0808 8020 133.

Frequently asked questions
Can I get free spins on Yggdrasil slots in the UK?
Sometimes, but studio-specific spins are uncommon, and none of our five partners currently gives welcome spins on a Yggdrasil game. UK casinos usually choose one or two games for their spins, and those are listed in the offer terms. If an offer elsewhere names a Yggdrasil title, confirm the casino holds a Gambling Commission licence, then check the spin value, wagering, deadlines and any winnings cap. The where to find free spins page explains where offers usually appear.
What are 50 free spins on Valley of the Gods worth?
At 10p a spin, 50 spins are £5 of play, and at Valley of the Gods' 96.2% RTP they return about £4.81 on average. Because the game is high volatility with a 5,800× max win, most batches of 50 spins will land below that figure and a few will land far above it. A single 10p spin can pay up to £580 at the game's max win, unless the offer caps winnings. The Valley of the Gods free spins page goes into more detail.
Which Yggdrasil slot has the best RTP for free spins?
In our checked data, Holmes & the Stolen Stones has the highest RTP at 96.8%, so 100 spins at 10p return about £9.68 on average. Vikings Go Wild and Jackpot Raiders follow at 96.3%. The difference between the highest and lowest RTPs in the Yggdrasil range is about 8p per 100 spins, so wagering, caps and spin value matter far more. In practice the casino chooses the game. Our high RTP slots for bonuses guide puts RTP in context.
Is Yggdrasil licensed by the Gambling Commission?
Yes. Published records show Yggdrasil holds a Great Britain licence as a business-to-business remote casino supplier, alongside licences in Malta, Gibraltar and the Isle of Man. That licence lets UK-licensed casinos offer its games. Your protections as a player, such as complaints handling and withdrawal rules, come from the casino's own licence, so check that separately on the public register. The how to check a casino licence guide shows how.
What is the max win on Vikings Go Berzerk Reloaded?
Our checked data lists a max win of 25,000 times the stake for Vikings Go Berzerk Reloaded, which works out at £2,500 on a 10p free spin. Its RTP is 96%, so 100 spins at 10p return about £9.60 on average, and a max-win result is extremely rare. Many free spins offers cap winnings below a game's maximum, so read the terms for a cap before relying on the headline figure. The free spins max win page explains how caps work.
Do free spins winnings on Yggdrasil games have wagering?
That depends on the offer, but in Great Britain wagering can't exceed 10 times the bonus since 19 January 2026. On £6 of spins winnings at 10x, you would need to wager £60, which at a 96.2% RTP game costs about £2.28 on average. All three partner spins offers on this page carry no wagering, so winnings arrive as cash. The no wagering free spins page lists what to look for.
Can a casino free spin trigger the bonus round on a Yggdrasil slot?
Yes. A promotional spin plays exactly like a paid spin at the fixed stake, so it can land the symbols that trigger the game's own free spins round. Winnings from that round count towards your spins winnings and follow the same terms, including any wagering or cap. The trigger rules differ by game, so check the help screen. Our how do free spins work page explains the difference between promotional spins and in-game rounds.
Are Yggdrasil demo games free to play in the UK?
Only after your age and identity have been verified. Since May 2019, UK-licensed casinos can't let anyone play free-to-play demo games until verification is complete, which closes a route under-18s once used to try slots. Once verified, demos let you see how a game's features behave without staking money. Demo play doesn't change the odds when you play for real. The age verification before play page covers the rule in full.
Why do some Yggdrasil games come from other studios?
Yggdrasil runs a partner programme called YGG Masters, through which other developers release games on its platform; its site lists 21 partners. In a casino lobby, those games may appear alongside Yggdrasil's own titles, so the studio named on the help screen tells you who built a particular slot. For free spins this matters only because RTP settings and features vary by game. Our sister page on free spins on Thunderkick slots looks at another independent studio.
Which partner offer is closest to free spins on Yggdrasil slots?
PlayOJO is the closest for simplicity: 80 free spins on Big Bass Bonanza at 10p each after a first deposit of £10 or more, with no wagering, for new UK customers outside Northern Ireland. Coral gives 100 no-wagering spins after a £10 slots bet, and Ladbrokes up to 500 over 10 days after £10 spent on slots, both on their own selected games. 18+ and terms apply. Compare them on our free spins hub.
