Putting on a fleece jacket and tall boots won’t be too much of a challenge to start the adventure on Mammoth Rampage, as wooly mammoths and saber-toothed tigers await your arrival to unleash the payouts on the reels. To do this, you’ll need to line up 3, 4 or 5 identical symbols and from left to right starting from the leftmost reel.

The bet can vary from $0.50 to $500 per spin. There are several categories of symbols that will pay more or less well.

Weak symbols such as the A, K, Q, J and 10 can pay between 5x and 100x the bet per line. Animals will make up the average payouts, the Wooly Mammoth pays between 50x and 300x while the Wooly Rhinoceros and Saber-tooth Tiger pay between 50x and 150x the bet per line. There is also the Dodo and the Fossilized Borrow that can pay between 20x and 120x. A Wild can help you fill or enhance a winning combination by counting as a wild for any symbol except the Mystery Egg.

Advantages & Disadvantages of Mammoth Rampage


  • Symbol transformation
  • Jackpot prizes
  • Base game modifiers
  • High paying symbols


  • RTP could vary among casinos

Mystery Egg

Find three mystery eggs to trigger bonus or free spins depending on what you find inside the egg. One of the three eggs will explode to release the Free Spins or Bonus and start the winning feature.

Bonus Game

If the mystery egg reveals a bonus, then the player will find a wheel of fortune consisting of different prizes as well as three jackpots. You can spin the wheel once for a chance to win up to 1000x the total bet with the Super Jackpot. It will also be possible to buy more spins until you win one of the three jackpots, but this comes at a cost, so it’s worth weighing up the pros and cons before making your choice.

Mammoth Rampage FS

In an Mystery Egg you can win mystery bet multipliers.

Free Spins & Collect Frozen Mammoth

If the Free Spins are activated after the Mystery Egg feature, then you will win free spins. A progress bar of average symbols will appear, the player needs to collect 5 Frozen Mammoths symbols to complete the progress bar and gradually turn the symbols into Mammoths capable of paying bigger wins. As the bonuses progress, the medium symbols will turn into Mammoths when enough Frozen Mammoths have been collected. At the same time, you will receive more Free Spins when a new transformation occurs.
