Mammoth Rage Overview

Created by producer Spinomenal, Mammoth Rampage takes players back to the ice age where enormous woolly mammoths and sabre tooth tigers roam the land. Although the setting may be still and peaceful, the action on the reels is anything but. With 1,024 pay lines, an extensive range of features and with excitement behind every spin, players will jump at the chance to play this dynamic and thrilling game. The RTP for Mammoth Rampage is 96%, and the top payout you can achieve from one spin is 1,000x the stake.

The features in this game start with the mystery egg feature triggered when three mystery eggs land on the reels simultaneously. If this happens, one large egg with a question mark will appear and reveal either the free spins game or the bonus game. The bonus game gives you a chance to spin a bonus wheel to win some big cash prizes. On the other hand, the free spins game takes you to a new board where you are trying to fill meters to trigger additional modifiers from within the game to maximise your winning potential. Finally, this game also has a bonus buy option that allows you to purchase access to the features.

Theme and Symbols

The theme for Mammoth Rampage is the ice age. From the looks of the various characters on the reels, this slot took its thematic inspiration from the children’s movie Ice Age rather than the geological phenomenon of periods of intense glaciation of the sea. As this game’s eponymous animal is the woolly mammoth, this slot must represent a time more than 800,000 years ago. Interestingly, there were many species of mammoth, yet the one we most often see in museums and films is the woolly mammoth, as plenty of fossils have been found to give us a better idea of what they looked like.

The background for this game is the tundra that blankets much of the earth’s surface at this point in time. The image has been created with an admirable level of detail, with the shadows and lighting looking very realistic indeed. It is a good job that there is plenty of colour and movement on the reels as the background is a bleak and featureless expanse looking up to a few snowy peaks looking unbelievably cold. When you enter special rounds and bonuses are triggered, snow even falls.
The playing window is a cold blue rectangle with a black interior, contrasting nicely with the colourful animal symbols.

The symbols for this game are split into low-paying, high-paying and special symbols. The low-paying symbols are the 10, J, Q, K and A in playing card royals. The most valuable of these symbols is the A which pays out at 2x the stake for the top combination. On the other hand, the more valuable symbols are the dodo, the sabre tooth tiger, the woolly rhino, and the woolly mammoth. The woolly mammoth is the most valuable of these symbols, worth 6x the stake for the top combination. The special icons finally are the mystery egg and the frozen wild symbol.

Game Play

Mammoth Rampage is played on a 5-reel, 3-row machine with 1,024 fixed pay lines. To win combinations, players must land three or more matching symbols on pay lines moving from left to right, starting from the leftmost reel.
The betting range for Mammoth Rampage is 50p to £500 per spin. To adjust their bet levels, players can toggle their stake up and down using the tool located at the bottom left-hand side of the screen.

Further information, including a short tutorial and a display of the paytable, can be found via the menu button in the right-hand corner of the screen. The spin and auto spin buttons are located in the centre of the screen.
Volatility for this slot is rated in the low range. The return to player percentage for Mammoth Rampage is 96%, which is average. The biggest payout that players can win on one spin is 1,000x your stake.


The first feature in this game is the wild feature. This bonus concerns the wild symbols you will occasionally see on the board. These icons substitute for other symbols to help players score more wins. These icons appear in both the base and free spins game.

However, the main feature content for Mammoth Rampage starts when players land three of the mystery egg icons on the board simultaneously. Do this, and a much larger egg will appear on the screen and explode. This explosion will reveal either the bonus game or the free spins game.

The bonus game is basically a wheel of fortune game that depending on your luck, could mean winning big instant cash prizes in the form of jackpots. If they don’t win a jackpot, players can buy another spin of the wheel to try again.
On the other hand, the free spins game is dictated by the influence of four progress bars. If you manage to collect five frozen mammoth symbols, you will be granted five extra spins. The frozen mammoth symbol will also be converted into a regular mammoth symbol.

This game also has a random symbol drop feature that distributes four to seven medium value symbols onto the reels in the base game, giving players a greater chance of triggering a win.
Finally, a bonus buy option allows players to purchase access to the bonus rounds. This option is not available in the UK.


Spinomenal has, in our opinion, created a highly entertaining and potentially lucrative game in Mammoth Rampage. The features add plenty of exciting layers to the gameplay, and the theme and graphics are high quality. The low volatility and decent RTP are also encouraging in terms of winning potential. The only real letdown here is the low top win of just 1,000x the stake.
