  • Advanced auto settings
  • Expanding reels
  • High maximum win
  • 8,192 ways to win
  • Very low RTP
  • High variance is not for the fainthearted


Let’s start our Mount M slot review by welcoming another Play'n Go free slot. This is a game developer with a very impressive portfolio that features everything from simple fruit-themed games to ones with sophisticated narratives and highly inventive graphics. Like Reel Time Gaming’s Fishin Frenzy free slot, Play’n GO has produced its fair share of light-hearted games, although Mount M is at the more sombre and dramatic end of its range.

The Mount M online slot has a five-reel, four-row grid with a potential 8,192 ways to win. The minimum bet is 0.10 and the maximum is 100.00. 

The paytable comprises five high-value symbols, four low-value symbols, and two special symbols. The high symbols are the mammoth, sabre-toothed tiger, rhino, hyena and dodo, while the low symbols are the four highest playing cards constructed from teeth and tusks. The wild is a W made from bones and the bonus scatter is a flaming bowl.

Theme, graphics and soundtrack

From its extended and dramatic introduction through to the graphics and animation of the grid, this is a brilliantly realised piece of work. The soundtrack of long, sonorous notes is an inspired choice. 

Mount M RTP and variance

The RTP is 94.2 per cent, which is very low for a slot game, and its volatility is high.

Always gamble sensibly. We support safe gambling initiatives such as BeGambleAware and must remind you that if you gamble for money, you could lose it. Playing games as no deposit slots is a good way to try them out before you commit money to them. 

If you decide to gamble for money, bet only what you can afford and make use of the timeout and self-exclusion features if necessary. When the game stops being fun, it is time to stop playing.

Mount M bonus features

Wild symbol

The wild symbol will substitute for every other symbol except the bonus and the scatter. It appears on reels two, three and four only.

Evolution free spins

Three, four or five bonus scatters will award 10, 15 or 20 evolution free spins respectively. Two, three, four or five bonus scatters will retrigger the free spins feature and give you an additional 3, 5, 8 or 10 evolution free spins. You can win up to 68 free spins.

Expanding reels and shatter respins

Collect orbs carried by the wilds to expand reels two, three and four to eight high. If you land a wild when the middle reels are glowing, this will award a respin.

Symbol upgrade

When the reels are expanded, any animal symbol will be upgraded to the mammoth and one extra free spin will be awarded. During the respin, one to four reel expansions are unlocked and the same number of animal symbols are upgraded.

Mount M review: our verdict

We have to take our hats off to Play’n GO, as it has done it again. Mount M has all the elements for a seriously compelling game, with strong visuals, very interesting gameplay, and a handsome top payout. On the downside, the RTP is disappointing and the variance won’t suit risk-averse players.

What are the RTP and variance of Mount M?

The RTP of Mount M is 94.2 per cent, which is almost two percentage points below the average for video slots. The variance, or volatility, is high.

What does RTP mean?

All slot games, including no deposit slots, are given an RTP rating. Standing for ‘return to player’, this is expressed as a percentage to give you an indication of the average amount you might expect to win back over the course of play compared with the amount you bet.

What is variance?

Variance or volatility describes the frequency of the payouts compared with their size. High volatility means you can expect bigger wins but they will occur less often, while a low volatility slot game will award payouts more often but each will be fairly modest.

Are the spins random?

All video slots, including no deposit slots, are run by random number generators. This makes the results of each spin impossible to predict or influence, ensuring every slot game is a game of chance.
