Mammoth Tundra Slot Review — Booming Games
Mammoth Tundra is a 5×3 video slot from Booming Games, played across 10 fixed paylines with a betting range from 0.10 to 500.00 per spin. The game leans on expanding wilds, stacked symbols and a free spins round that upgrades symbols mid-play, set inside a snow-covered Ice Age scene populated by mammoths and other frozen-tundra wildlife.
Core Gameplay Experience
The 5×3 grid and 10 paylines keep the base game compact compared with slots running 20 or more lines, which means each spin resolves quickly and the visual focus stays on a handful of symbols rather than a cluttered board. Booming Games, the studio behind Mammoth Tundra and founded in 2014, builds its catalogue around this kind of straightforward reel-and-payline structure rather than cluster-pays or Megaways grids, and the Booming Games slots library carries that house style throughout.
Visually, the slot commits fully to its Ice Age setting: white snowfields, ice formations and a woolly mammoth as the headline symbol sit alongside other tundra animals on the reels. Players drawn to animals and nature themed slots get a clear thematic match here, with the cold, prehistoric backdrop distinguishing it from the jungle or savanna settings more common in that category.
Features and Mechanics
Expanding wilds and stacked symbols are the two mechanics that shape most base-game spins in Mammoth Tundra: a wild landing on a reel expands to cover the full reel, and stacked symbols raise the odds of that wild lining up across multiple positions in one hit. The free spins round is the other main draw, and per AboutSlots.com it opens with 12 initial free spins during which symbols upgrade as the round progresses, turning lower-paying icons into higher-value ones as spins continue. Scatter symbols trigger the round, symbol removal and substitution mechanics keep the reels active during the bonus, and extra free spins can extend the round beyond its starting count. Anyone comparing bonus structures across providers can browse the wider set of slots with expanding symbols to see how this mechanic varies elsewhere.
RTP, Volatility and Payout Model
Mammoth Tundra runs at a 95.4% RTP with a medium-high volatility profile, meaning the game is built for less frequent but comparatively larger wins rather than steady small returns. In practical terms, a medium-high-volatility payout model like this can produce noticeable losing streaks between hits, so bankroll and stake size should be set with that pattern in mind rather than an expectation of frequent small returns. The 95.4% RTP sits in the 29th percentile of the 4,445 slots in our catalog with a published RTP figure, against a catalog median of 96%, placing it on the lower side of that range. A medium-high-volatility profile like this one is shared by 63% of the 4,737 slots in our catalog, so the risk pattern itself is common even if this particular RTP sits below the median.
Long series of spins without a win are a realistic outcome on a medium-high-volatility title like this one, so setting a stake size and loss limit before playing matters more than on lower-volatility games. The demo mode is a practical way to see how the expanding wilds and free spins round actually trigger before committing real money to it.

Similar Expanding Wilds Slots from Other Studios
| Game | Studio | RTP | Volatility | Max win |
|---|---|---|---|---|
| Wild Anubis | Amatic | 97.03% | Medium | x1000 |
| Forgotten | BGaming | 96.91% | High | x7500 |
| Wild Fruit Jam | Belatra Games | 96.09% | High | — |
| Mega Shark | Amatic | 97.1% | Medium | — |
Forgotten offers the highest ceiling of this group at 7500x its stake, while Mammoth Tundra’s 500x cap places it as the lower-ceiling option among the compared titles, better suited to players prioritising a shorter, contained bonus round over chasing an outsized top prize.
Mammoth Tundra suits players who enjoy a compact 10-payline structure and are willing to accept a medium-high-volatility swing pattern for the chance at an expanding-wild hit or an upgraded free spins round. It is a weaker fit for players who want frequent small wins or a high max win ceiling, since the 500x cap is modest next to the 1000x-7500x range seen among the compared titles above.
How to Play Mammoth Tundra Online
Demo mode is the practical starting point for Mammoth Tundra: it lets a player see how often the expanding wilds land and how the free spins round upgrades symbols, without staking real money first. The full title, along with other slots, can be tried through the demo game catalogue. Booming Games titles run at 94 casinos in our catalog as of 2026, including Wild Tornado Casino, WinSpin Casino and Rooster Bet Casino; before playing for real money at any operator, check its licensing and current terms rather than relying on the demo experience alone. At a 0.10 stake, a 100-spin session needs a 10 bankroll before any wins are counted, and that ratio scales linearly with stake size — a useful baseline given the game’s medium-high-volatility payout pattern.
Conclusion
“Mammoth Tundra trades payline variety and win frequency for a tight, medium-high-volatility bonus round built on expanding wilds and symbol upgrades.” — Search-Casino Editorial Team
Mammoth Tundra is a straightforward, feature-focused slot from Booming Games rather than a high-ceiling jackpot game: its 95.4% RTP and medium-high volatility mean sessions can run cold for stretches before the expanding wilds or free spins round pay off. It fits players who want a compact 10-payline Ice Age title with a defined bonus mechanic, and is less suited to those chasing frequent wins or a large maximum payout.
