How to Play

To start playing 1 Reel Mammoth for real cash or for fun right now, follow our instructions:

  • Launch the slot on your laptop or mobile phone
  • Click the ‘?’ symbol to see the game’s rules and paytable

1 Reel Mammoth is a unique slot machine in many regards because, as you might have already guessed, its game board consists of only 1 reel. It makes the gameplay of this slot only more immersive, though. Basically, your task is to fill the prize bank up to the top by getting complete symbols on the reels. If the symbol appears only partially, though, you won’t get any prize.

1 Reel Mammoth RTP and Volatility

7.4 

1 Reel Mammoth has got an RTP rate of 95.42% and high volatility.

This slot machine has only one reel, which means that there are no active paylines. Most of your winning potential in 1 Reel Mammoth depends on your own luck and, of course, the volatility of the slot.

Theme

8 

Spinomenal is a company known for its high-quality wildlife-themed slots, and 1 Reel Mammoth is another glaring proof of that. The slot takes gamblers back to the Ice Age, acquainting them with various kinds of species that are believed to have lived back then. The slot’s interface consists of the breathtaking scenery of ice and snow-covered hills, and all your playing rounds are accompanied by an animation of the falling snow. The visual details are impressive, and all symbols that may appear on the reel look highly realistic and smooth.

The regular paytable in 1 Reel Mammoth consists of 3 wild animal symbols, including a mammoth, that may appear on the reel and guarantee you progressive stake multipliers as you make your spins. The progressive win bars will fill up level after level each time you manage to land one of the animal symbols on the reel.

At the same time, there are 2 special symbols in 1 Reel Mammoth. The first one, Wild, equals landing all 3 progressive win symbols at the same time. If you get the Wild symbol on the reel, you’re a lucky one: all bars will progress to the next level! However, be aware of the Reset Bank symbol. Landing it will reset all your winning bar progressions back to 0.
