Colossal Vikings

The OCR review


Colossal Vikings is set in the familiar world of ice-capped mountains, snow-covered forests, and raging berserkers ready to plunder and pillage. Where Colossal Vikings stands apart is in the presentation and the features. It’s a beautifully rendered piece of artistry with a fitting soaring soundtrack and big characters that suit the name ‘Colossal’.

But it’s not just the giant musclebound marauders wo are colossal, it’s also one of the big features in the game – colossal symbols and maybe even some colossal wins if your raiding party lines up.

Gameplay is fast and smooth with some exciting action that will keep the thrills going for online slots players as they hunt down the elusive wins. With a high volatility, these wins are quite few and far between, but they are definitely worth it if you can land some colossal symbols and wild multipliers. The max win in the game sits at 1,125x your stake which seems low but, when you factor in that players can wager some steep amounts, it seems fair.

The 5×3 grid is filled with Viking-inspired symbol like helmets, axes, horns, and the three giant Norsemen, all framed in scroll-etched stone or timber. It’s a beautiful imagining of the Norse tropes, and Booming Games have outdone themselves with their attention to detail and their reworking of a popular theme.

Colossal Vikings is a hit at OCR, not least because we really enjoy a good Viking saga. But when we get one of our favourite themes with added features and unusual mechanics added? That’s a rousing skål from us! (For those players who have never watched a Viking series, skål is a Norse toast like ‘cheers’).


There are Viking symbols aplenty in Colossal Vikings, each one engineered beautifully by Booming Games.

Symbols from lowest paying to highest: Horn; Axe; Helmet; Shield; Broken Horn Viking; Two Horn Viking; Eye Patch Viking.

Wild Symbols are Wild and substitute for all paying symbols.

Reveal Wild symbols reveal multiplier amounts.

Runic Circles are Scatters and trigger Free Spins.


Booming Games have done a superb job of creating a familiar Viking world with small touches that make it unique to Colossal Vikings. The oversize characters, the transparent reels, the small animations of the birds and the Northern Lights in the background – it all combines to create a fantastic and immersive experience for players.


The orchestra-driven soundtrack fits the theme perfectly, soaring instruments that create an epic feel and recreate the sense of glory and the sense of mayhem that made the Viking-era so famous.

Bonuses and extras

Colossal Vikings has some interesting and unusual features that really elevate it from the standard online slots.


The Wild symbol substitutes for all paying symbols.

Reveal Wild Multipliers

Added to the wilds are Reveal Wilds that have 2x, 3x, 5x, and 20x multipliers.

Free Spins

Landing 3x or more Rune Scatters will trigger Free Spins. 3x Scatters = 8x Free Spins, 4x Scatters = 10x Free Spins, and 5x Scatters = 12x Free Spins.

Colossal Symbols

Major Symbols (the three Vikings), Wild Symbols, and Reveal Wild Multiplier Symbols can all randomly land as Colossal Symbols to add extra opportunities for lining up the wins. In the base game, Colossal Wilds land as 3×2 symbols. In Free Spins, Colossal Symbols land as 3×2 or 3×3 symbols.

Reveal Wild Multiplier feature

Soaring soundtrack


High volatility

Could use more features

The OCR verdict

Colossal Vikings is a thrill a minute when it comes to action and amazing graphics. It may not pay out nearly as much, or as highly, as we would like, but it’s still very high on our list of favourite Viking-themed online slots games. The relative scarcity of wins and big feature triggers does add to a sense of heightened anticipation whenever we spin the reels, and the epic soundtrack does nothing to lessen our heart palpitations as we hope for those Rune symbols to land and set off our free Spins.

Colossal Vikings does seem stingy on the wins but, if your luck hits juts right, you could hit a 3×3 Colossal Reveal Wild Multiplier during Free Spins to really set up your take of glory.

A great game from Booming Games.
