Big Mammut: Experience the Ice Age With Re-Triggerable Free Spins and 2x Multipliers

Snehal Gupta rated this game:

2.5 out of 5

Survive the Ice Age in Spin2Win’s Big Mammut, where sabretooth tigers, mammoths, and cavemen face off. Dodge meteor showers to unlock re-triggerable free spins with 2x multipliers, and land stacked symbols for bigger payouts. This snow-covered battlefield is ready for action. Here’s what you need to know before you begin.

The game opens in the heart of a blizzard, with prehistoric animals circling a 5-reel, 4-row grid. It offers 1,024 ways to win, so landing three or more matching symbols on adjacent reels from left to right is all you need to form a winning combo. I also liked that multiple combinations could pay out in a single spin, making wild symbols that can transform into other paying symbols far more valuable over time.

Right from the start of my session, I was landing wins constantly. The large number of active paylines made it easy to score a win every few spins, with payouts usually ranging from 0.10x to 1x my bet. These lower payouts were mostly due to how little the symbols paid. The lower ones dropped returns as low as 0.05x my bet, and even the top stacked symbols only reached 2.5x my bet, which wasn’t great. While the frequent wins were nice, the small payouts made them feel underwhelming and impactless.

The best way to boost my bankroll in the base game was by landing multiple stacks of the higher-paying symbols. With two or three sabretooth tigers stacked on the first and second reels, I occasionally picked up payouts as high as 18.10x. Still, my bankroll would’ve kept shrinking if I hadn’t triggered the free spins bonus by landing 3 scatter symbols. The highlight of the bonus is that it can be re-triggered up to three times, and every win gets a 2x multiplier.

With the 10 free spins I received from triggering the bonus, I scored a 25.20x payout on my first round. The free spins felt unpredictable overall, with total payouts ranging from as low as 2x to as high as 34x my bet in later triggers. Big Mammut offers a detailed Ice Age setting and uses familiar mechanics for a relaxed gaming experience. You can try the Big Mammut free demo above or play it for real money at the casinos listed below.

looked better than it played

That €16.50 win on a €10 bet really shows the issue: even with stacked wilds and decent symbols, the payout barely covers the spin plus a little extra. Visually it looks like a big hit, but the math says “meh.”

Bonus is the only hope

The free spins with 2x multiplier are the only thing that gave me decent returns. Outside that, most wins are tiny and don’t feel rewarding. Definitely more of a “play for the visuals” kind of slot.
