The game is like a primordial volcano, constantly fueled and pressure builds the more it consumes, hot vapour and molten magma expanding relentlessly into the enclosed rock. Until finally, the mountain of earth can no longer contain it, and there is an eruption of an enormous magnitude!
In the base game, every winning tumble increases the global multiplier, with 4 tumbles triggering the feature. There is a maximum multiplier x8, and given a maximum of 117 649 ways to win, it is not unheard of to enter the feature with a 1500x stake win, before it even starts.
*Max stake is interchangeable and can be lowered depending on your limits.
Free spins start with the ground trembling and the reels shaking, as they make way for the prehistoric “Mammoth Reel”, an additional reel which, when caught, expands to a frightening height of 9 symbols! It also adds an additional multiplier, 5 extra spins, and Sticky Wilds!
You will also find Iron Dog’s instantly recognisable “Lock-it Reels” system, where when reels expand to their maximum height they stay locked, at it's most terrifying, there can be 6 reels locked at 7 symbols, and the Mammoth reel locked at 9, resulting in over a MILLION ways to win.... now that is Mega!
