Colossal Vikings is a high-volatility, five-reel, 20-payline slot from Booming Games, released in August 2019, with an RTP of 95.32% and a max win of x1125 times the stake.
The Norse theme leans into snow-bound forests and heavy Viking iconography, and the high-volatility profile suits players comfortable with longer stretches between wins in exchange for a shot at the x1125 ceiling.
Colossal Vikings Slot Review — Booming Games
Colossal Vikings is a five-reel, three-row video slot from Booming Games, released on 21 August 2019. The game runs on 20 fixed paylines and combines a Norse raiding theme with a high-volatility payout model, an RTP of 95.32% and a maximum win of x1125 the stake.
Core Gameplay Experience
The reel grid sits inside a Scandinavian winter setting: bare forest trees, packed snow and a colour palette built from brown, blue and white carry the Viking theme through the frame, while helmets, shields and a war hammer appear as recurring visual motifs rather than as isolated bonus icons. Players interested in similar historical and mythological settings can browse other Ancient & Historical themed slots in the wider catalogue.
Bet sizing runs from 0.2 to 400.0 per spin across the fixed 20 paylines, a range wide enough to cover both cautious low-stake testing and larger bets from players chasing the high end of the payout table. Base-game spins move at a standard pace, with the visual weight of the theme carried mainly through symbol design rather than through animation-heavy transitions between spins.
Features and Mechanics
Colossal Vikings combines five mechanics: Wilds, a Mega symbol, a Multiplier, Scatter symbols and a Free Spins round. The Wild substitutes for regular paying symbols across the grid, and the Mega symbol occupies a 3×3 block across three reels and three rows when it lands, replacing several smaller symbols in one placement and increasing the chance of a connected payline. Scatter symbols trigger the Free Spins round; per the provider’s own game rules, landing 3 to 5 scatters awards between 8 and 12 free spins, and wild multipliers of 2x, 3x, 5x or 10x can apply to wins landed during that round.
Colossal Vikings does not include a bonus buy option, so entry into the Free Spins round depends on scatter landings during regular play rather than on a direct purchase.
RTP, Volatility and Payout Model
Colossal Vikings has an RTP of 95.32% with a high-volatility profile. In practice, that combination means the game pays out, on theoretical average over a large number of spins, close to 95.32 units for every 100 wagered, while individual sessions can swing well away from that average because wins are spread unevenly rather than arriving at a steady rate. A max win of x1125 the stake sits below the highest ceilings among comparable slots, which places Colossal Vikings closer to a medium-ceiling, dry-spell-prone profile than to a jackpot-chasing design. These figures reflect the version checked under Search-Casino’s evaluation framework as of 2026.
With a max bet of 400.0 per spin, a short losing run near the top of that range can use up a bankroll quickly under a high-volatility model. Setting a per-session budget well below the 400.0 ceiling and testing the scatter and free spins frequency in demo mode first are two practical ways to see the pace before wagering real money.
How Colossal Vikings Compares to Other High-Volatility Slots with Free Spins and Multipliers
| Slot | Studio | RTP | Volatility | Max win |
|---|---|---|---|---|
| Colossal Vikings | Booming Games | 95.32% | High | x1125 |
| Book of Sun Choice | 3 Oaks Gaming | 95.76% | High | — |
| Jack Potter and The Book of Dynasties | Apparat Gaming | 96.06% | High | — |
| Admiral | Barbara Bang | 96% | High | x2000 |
| Zuma Empire | BBIN | 96.00% | Medium | — |
Admiral carries the highest confirmed max win of this group at x2000, roughly double the x1125 ceiling on Colossal Vikings, while Zuma Empire is the only medium-volatility title among the five and suits players who want steadier hit frequency over a high ceiling. Players who already accept the swings of Book of Sun Choice or Jack Potter and The Book of Dynasties will find a similar high-volatility rhythm in Colossal Vikings, just with a lower RTP and a more modest top payout.
Colossal Vikings fits players who are comfortable with a high-volatility Viking-themed slot and who plan bets well under the 400.0 maximum, treating the Mega symbol and multiplier-driven free spins as occasional highlights rather than a frequent income source. It is a weaker fit for players who want frequent small wins or who are working with a tight session bankroll, since the high-volatility profile can produce longer runs without a payout between free spins triggers.
How to Play Colossal Vikings Online
Demo mode is the practical way to see how often the scatters land and how the Mega symbol and multiplier interact with the paylines before betting real money. The free demo version on this page runs on the same 20-payline structure and bet range as the real-money game, without needing an account or deposit.
Beyond this page, the broader slots category carries free-to-play versions of other high-volatility titles for the same kind of pre-play testing. Booming Games titles, including Colossal Vikings, are available at 91 casinos in the current catalogue tracked by Search-Casino, among them BetLabel, Spinbetter and Slotsgem; availability, bet limits and any promotions still depend on the specific operator’s own terms. A fuller list of the studio’s games and the casinos offering them sits on the Booming Games slots & casinos hub.
Conclusion
“Colossal Vikings rewards patience with a Mega symbol and multiplier-driven free spins round, not with frequent small wins.” — Search-Casino Editorial Team
Colossal Vikings suits players who treat a Booming Games slot as a long-session, high-volatility pick rather than a fast-cycling low-risk game, and who are comfortable with a x1125 ceiling that sits below the highest payouts in its comparison group. Players prioritising frequent hits or a larger jackpot-style ceiling are better served elsewhere in the catalogue; those testing the pace first can do so in the demo version referenced above.
