Siberian Storm slot review

Siberian Storm slot: what you’re getting

Siberian Storm is one of IGT’s MultiWay Xtra games, a format where the reels are different heights and wins count from either end. Its maths is medium volatility, which sits in the middle of the range between steady and swingy.

Two common figures aren’t published in the specifications we rely on: the release date and the maximum win. Where those matter, the game’s help screen in your casino app is the place to look.

How the features work in Siberian Storm

The game is simpler than most modern slots: there are no collect symbols, multipliers or expanding grids in its published description. What makes it distinctive is the way wins are counted.

MultiWay Xtra and two-way wins

Most ways games count matching symbols from the leftmost reel only. Siberian Storm counts them from the left and from the right, so a run of symbols that starts on reel 5 and connects back towards reel 1 can also pay. It still needs the symbols on adjacent reels, in any row.

The wild

The wild appears only on reels 2, 3 and 4, the middle three. Because it can’t land on the outer reels, it can’t start a winning run, but it can fill the gaps in the middle that join one end to the other.

Free spins

Five Tiger Eye symbols trigger eight free spins, and landing them again during the round retriggers it. That is the whole published bonus, so the game relies on frequent mid-sized returns from its 720 ways rather than one dramatic feature. The casinos.com Siberian Storm page (opens in a new tab) gives the same summary of the format.

Why the Siberian Storm slot has 720 ways

In a ways game, the number of ways is the number of rows on each reel multiplied together. Siberian Storm’s diamond shape gives this:

So 3 x 4 x 5 x 4 x 3 = 720. Paying in both directions doesn’t change that count; it means each set of positions can be read from either end. For comparison, a standard 5x3 grid gives 243 ways, which you’ll see on slots such as Vikings. The paytable glossary entry shows where a game lists this.

Siberian Storm RTP: why the version matters

Siberian Storm is published in more than one version, with RTP from 92.52% at the bottom to 96% at the top. The difference looks small, but the house edge nearly doubles: 7.48% against 4%.

Those figures are averages over very long play; a single session can land far from them in either direction. The point is comparative: the same hour on the lower version costs almost twice as much on average. Apps don’t carry lower RTP because they’re apps; the version is chosen by the operator, and our explainer is RTP lower on casino apps? covers that myth.

How to check which Siberian Storm version an app runs

UK rules require operators to make game rules and return information available to players, which the Gambling Commission sets out in its technical standard on game descriptions and the likelihood of winning (opens in a new tab). Here’s how to use that on your phone:

1. Open the casino app and log in.
2. Search the game lobby for Siberian Storm; if it isn’t listed, that casino doesn’t carry it.
3. Open the game, then open its information, help or paytable screen before spinning.
4. Find the stated return to player figure for that version.
5. Compare it with 96%: anything near 92.52% is the lower-return version.
6. If you use more than one app, repeat the check in each, because operators can pick different versions.

Medium volatility on a £20 budget

Volatility describes how unevenly a slot pays. Medium means more frequent mid-sized returns than a high-volatility game, but still plenty of losing spins. On £20, that typically means a budget lasts longer than on an extreme game, though nothing about any session is predictable.

At 10p a spin, £20 is 200 spins if you never restake winnings; at 50p, it’s 40; at £1, it’s 20. Most players restake as they go, so the amount staked over a session is usually much higher than the deposit. That’s why a fixed deposit limit is a better control than trying to remember what you’ve spent.

Playing Siberian Storm on iPhone and Android

Siberian Storm runs inside casino apps and mobile sites on iPhone and Android, opened from the lobby like any other slot. The diamond layout means the middle reel is the tallest, with five rows, so it’s worth checking that the symbols are comfortable to read on your screen size.

Whether a game offers portrait as well as landscape depends on the version the casino runs, so rotate the phone to find out. Older phones can struggle with heavier games, and our guide to casino apps on older phones explains what to check.

UK rules that apply to the Siberian Storm slot

On a UK-licensed app, each spin of Siberian Storm takes at least 2.5 seconds, and you tap for each one: autoplay, turbo and slam-stop have been banned on online slots since 31 October 2021. Returns equal to or lower than your stake can’t be celebrated as wins, and since 17 January 2025 your net spend and time played must be visible as you play.

Stakes are capped at £5 a spin if you’re 25 or over (from 9 April 2025) and £2 a spin if you’re 18 to 24 (from 21 May 2025), as set out in the Gambling Commission’s stake limit guidance (opens in a new tab). Our page on UK slot stake limits explains how operators apply them by age. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players.

Siberian Storm vs other IGT slots

IGT is headquartered in Las Vegas and has been owned by Apollo-managed funds since 1 July 2025. Here’s how Siberian Storm compares with others we review.

Cleopatra is the closest match on volatility. Wolf Run is another animal-themed IGT game at the gentler end, and Pharaoh’s Fortune has the highest top-version RTP in the group.

Siberian Storm slot review: our verdict

Siberian Storm is a straightforward, medium-volatility slot that suits players who like frequent mid-sized returns more than chasing a single big bonus. Its weak point is the version spread: on the 92.52% version, it is one of the costlier mainstream slots to play.
