Mammoth Tundra (Booming Games) – Review & Demo Play

Mammoth Tundra Slot Overview

Mammoth Tundra is a 5 reels, 3 rows, 10 paylines video slot from Booming Games set in a freezing tundra under the Northern Lights. It runs via HTML5 on mobile and desktop, with Autoplay and Turbo tucked inside the spin menu. Bets range from a Min.bet of 0.10 to a Max.bet of 500, paired with an RTP of 95.4% and medium/high volatility. The max win sits at 500X the bet, so the appeal rests on the features, not on huge prize pots or any Bonus Buy.

Mammoth Tundra Slot Information

The layout is clean, with the reels centred and the logo on top. You create a winning combination by landing 3 or more matching symbols on adjacent reels starting from the leftmost reel. The background shows snow, icy mountains, and gusty wind, while the UI keeps things simple on phones, tablets, and desktops. In my sessions the hit rate felt above 15%, which tracks the stated figure and yields a steady flow of small to mid-range wins in the base before the features kick in.

The lower-paying set is green clover, blue diamond, yellow heart, and red spade, paying 10X for 5 of a kind. The higher-paying row is pink bird, purple sloth, blue boar, yellow bear, green wolf, and red tiger, paying between 20X and 50X for a five-symbol hit. The Mammoth is the Wild Symbol, substituting for all except the Scatter. The Free Spins Scatter carries direct payouts of 2X, 20X, or 50X the bet for 3, 4, or 5 landed, on top of entry to the feature.

Mammoth Tundra Slot Features

Wild Symbols land only on reels 2, 3, and 4. When they appear, they expand to cover the whole reel and substitute for all regulars except the Scatter, opening up lines you would otherwise miss on a 10 payline layout. I like how these expanding wilds show up in both the base and Free Spins, as they shape the symbol upgrade path and can swing a spin from nothing to a tidy line-up across the grid.

Free Spins in Mammoth Tundra trigger by landing 3 or more Scatters, awarding 12 Free Spins straight away. Scatters also pay 2X, 20X, or 50X the bet for 3, 4, or 5. During the round, each Wild landing grants extra spins: 1 Wild gives 1, 2 Wilds give 3, and 3 Wilds give 5 additional spins. Landing 3+ Scatters again during Free Spins retriggers 12 more spins, so the round can stretch out nicely when the Mammoth keeps turning up.

Major Upgrades in Mammoth Tundra sit at the heart of the Free Spins. The progressive Free Spins Feature uses reel strips that change as you level up from 1 to 6, with each Wild in view pushing the level by one. Level 2 turns all Pink Bird to Purple Sloth; Level 3 turns Purple Sloth to Blue Boar; Level 4 turns Blue Boar to Yellow Bear; Level 5 turns Yellow Bear to Green Wolf; Level 6 turns Green Wolf to Red Tiger.
