Siberian Storm free spins are either casino spins credited for IGT’s 720-ways slot or the bonus round built into the game. What 100 spins at 10p are worth depends heavily on the version: about £9.25 on average at the 92.52% RTP version and about £9.60 at the 96% version, from the same £10 of stakes.
Siberian Storm’s RTP varies by version from 92.52% to 96%, one of the widest ranges among popular slots.
100 spins at 10p return about £9.25 to £9.60 on average, depending on the version the casino runs.
With 10x wagering, the low version leaves around £2.33 of average value from those spins, against about £5.76 at 96%.

What Siberian Storm free spins can mean
A casino can give you a bundle of spins to use on Siberian Storm, paid for by the casino at a fixed stake. Or the phrase can mean the game’s own free spins round, which IGT built into the slot. The first depends on the offer’s terms; the second on the game’s rules, which are printed in its help screen.
Either way, the single most important number for this game is its RTP version, because Siberian Storm is supplied with a wide spread of them. Our free spins hub has the current offers, and free spins on IGT slots covers the studio’s range.
Siberian Storm RTP: one game, a wide range of versions
Siberian Storm’s published RTP varies by version from 92.52% to 96%. The casino chooses which version to offer, and the figure in use is normally shown on the game’s help or paytable screen. That 3.48-point spread means the house edge ranges from 4% to 7.48%, nearly double at the low end.

On a spin bundle the gap is modest, about 35p per 100 spins. On your own money it grows quickly: £100 staked costs about £7.48 on average at the low version and about £4 at the high one. See free spins on high RTP slots for games with consistently higher figures.
How the RTP version changes Siberian Storm wagering
Wagering is where the version matters most. Suppose your spin winnings came as bonus funds with 10x wagering, the highest a UK casino can set since 19 January 2026. Here is the average result for 100 × 10p spins at each end of the range.
100 × 10p Siberian Storm spins with 10x wagering on winnings
Siberian Storm uses an unusual diamond-shaped layout: three symbols on the outer reels, four on the next pair and five in the middle. It pays across 720 ways, and wins count in both directions, from left to right and from right to left. The stake covers all ways on every spin, so a 10p promotional spin plays the whole layout.
Paying both ways makes small wins land a little more often, but it is already built into the RTP; it doesn’t add value on top. The paytable shows exactly how combinations are counted.
Medium volatility: what to expect from a spin bundle
Siberian Storm is rated medium volatility. Compared with high-volatility games, returns are spread more evenly, so a 50 or 100-spin bundle is a little more likely to land in the region of the average. It is still a short sample, and both very poor and very good results happen.
We don’t have a verified maximum win figure for Siberian Storm, so we haven’t stated one; check the help screen. If an offer caps spin winnings, that cap applies first; see what is a fair max cashout.

Siberian Storm free spins no deposit
No deposit spins on Siberian Storm occasionally appear at UK casinos, but our partners don’t offer any no deposit bonus. Where they exist, expect a small number of 10p spins, a cap on winnings, and often wagering on top. Twenty no deposit spins at 10p are £2 of stakes, returning about £1.85 to £1.92 on average depending on the version. Age and identity checks still apply before play. See free spins on registration.
How to trigger free spins on Siberian Storm
IGT sets the rules for the game’s bonus round, and we don’t have a verified description of the trigger or spin count, so we won’t quote one. Open Siberian Storm, go to the paytable or help pages and read the free spins section: it explains which symbols start the round, how many spins it awards and whether it can be retriggered.
Casino spins play the normal game, so they can usually trigger the round as a paid spin would. Feature buys aren’t offered on slots supplied to Great Britain. See can free spins trigger the bonus round.

Frequently asked questions
What is the Siberian Storm RTP?
It varies by version, from 92.52% to 96%. The casino chooses which version it runs, and the figure in use is normally shown on the game’s help or paytable screen. At the low end the house edge is 7.48%; at the high end it is 4%. For 10p spins, that means an average return of roughly 9.25p to 9.6p per spin. Check the version before you play with your own money or bonus funds. See our RTP glossary entry.
How much are 100 Siberian Storm free spins worth?
One hundred spins at 10p are £10 of stakes. They return about £9.25 on average at the 92.52% version and about £9.60 at the 96% version. Medium volatility means results spread less widely than on high-volatility slots, but any single bundle can still land well above or below these figures. With no wagering, the full amount is cash; with 10x wagering, much less is left. See what is the average win from 100 free spins.
Can I get Siberian Storm free spins with no deposit?
Not from our partners, which don’t offer no deposit bonuses. Some UK casinos occasionally give a few no deposit spins on named slots, usually at 10p, with a cap on winnings and sometimes wagering. You still have to pass age and identity checks first. If wagering applies and the casino runs the 92.52% version, very little average value may be left. Read are no deposit bonuses a scam for warning signs.
Are Siberian Storm free spins with no wagering better?
Yes, and especially on this game. Without wagering, the RTP version hardly matters for a spin bundle, because the casino has paid the stakes and winnings are cash. With 10x wagering, the low 92.52% version leaves only about £2.33 of average value from 100 × 10p spins, against about £5.76 at 96%. No wagering also avoids max-bet rules and deadlines. See are wager free spins better.
How do you trigger free spins on Siberian Storm?
Check the game’s help screen for the exact trigger, because we don’t have a verified description from IGT. The paytable explains which symbols start the bonus round, how many spins it awards and whether you can win more during it. Casino promotional spins use the normal game, so they can usually trigger the round in the same way a paid spin can. Read can you retrigger free spins for how retriggers usually work.
What does 720 ways both directions mean in Siberian Storm?
It means the game counts winning combinations across 720 possible ways on its 3-4-5-4-3 layout, and it pays them from left to right and from right to left. The stake for each spin covers all of them, so a 10p promotional spin plays the full layout. Paying both ways is part of how the RTP is reached, so it doesn’t add value beyond the published figure. Our page on game round explains how a spin is defined.
How can I tell which Siberian Storm RTP version a casino runs?
Open the game, tap the information or menu button and go to the rules or paytable pages; the theoretical RTP is usually printed near the end. If it isn’t shown, ask the casino’s support team before you use a bonus on the game, and keep their reply. Knowing the version helps you work out the real cost of any bonus wagering. Our high RTP slots for bonuses guide explains why this matters.
Can I use Coral or Ladbrokes free spins on Siberian Storm?
Only if the offer lists it among its selected games, and we can’t confirm that it does. Coral gives 100 free spins at 10p after a £10 slots bet; Ladbrokes gives 50 a day for 10 days, up to 500, after £10 of slots play. Both are no wagering, 18+ and terms apply, and both exclude some deposit methods such as PayPal and prepaid cards. Check the game list on the promotion page; see Coral eligible games.
