Slot Summary

A full-reel Wild can start a bonus sequence that keeps adding spins and improving its premium symbols. Mammoth Tundra uses that promise as its defining idea, with the Wild expanding on the middle reels before serving a second purpose during Free Spins. Booming Games ties each Wild to both extra time and a Symbol Upgrade, making the feature's changing symbol set more important than the plain line game.

How It Plays

Regular wins are evaluated from left to right on fixed lines. The Wild may land on reels 2, 3, and 4, then expand to fill its entire reel.

The Wild substitutes for regular symbols but not the Scatter Symbol. Its location across the middle reels gives it the chance to connect matching symbols on both sides.

Theme & Atmosphere

Mammoth Tundra places Animals in an Ice and Winter setting, using prehistoric wildlife to distinguish its Wild Symbol and higher-value symbols from the card ranks.

The Nature presentation stays focused on the frozen landscape and its creatures. The mammoth is functional as well as thematic because it represents the reel-filling Wild.

Features & Win Potential

An Expanding Wild fills its reel whenever it lands on one of the eligible central reels. The same behavior remains active during Free Spins.

The Symbol Upgrade process changes lower premium symbols into stronger ones as Wilds appear during the feature, progressively reducing the number of weaker animal symbols.

Free Spins Scatter Symbol Medium/High Medium volatility Symbol Upgrade 5 Reels Expanding Wilds Additional Free Spins Expanding Symbols 10 Paylines Fixed Jackpots Remove Symbols Substitution Symbols

Bonus & Free Spins

Three or more Scatter Symbols award 12 Free Spins. Another qualifying Scatter result during the round adds 12 more, so the feature can extend repeatedly.

During Free Spins, one, two, or three Wilds add 1, 3, or 5 spins respectively. Each Wild also advances the Symbol Upgrade level.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (95.40%), with wins capped at its top multiplier (500×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
