Play'n Go's Mount M is a volatile prehistoric animal-themed slot featuring 5x4 reels and 1,024 win ways by default.

The maximum payout is 13,000 times your wager.

Slot Features

Mount M transports you to the ice period, and the 5x4 grid is filled with prehistoric animals such as dodos, woolly rhinos, sabre-tooth tigers, and the mammoth as the highest-paying symbol. The premium animal symbols award between 0.5 and 2 times your bet for 5 of a kind, while the golden Wild symbol can only appear on the middle three reels. The wild substitutes for pay symbols to help complete wins, and it can also activate the only feature of the main game. The three middle reels are occasionally highlighted by a frame, and the Shatter Respin feature is triggered when at least one wild symbol appears on all three reels simultaneously. The three middle reels will then randomly expand by one to four rows, giving you a maximum of 8,192 opportunities to win. One of the premium symbols is turned into the highest-ranking Mammoth for each additional row, and the reels are reset following the respin.

The Evolution Bonus Round is activated by landing 3, 4, or 5 scatter symbols in view, which awards 10, 15, or 20 free spins, accordingly. When 2, 3, 4, or 5 scatters appear during the same free spin, you receive 3, 5, 8, or 10 additional spins, accordingly. Collecting orb overlay symbols from wild symbols will unlock the extra rows above the middle three reels and upgrade animal symbols to the Mammoth.

The symbol transformation begins with the lowest-value premium symbol, then 5, 14, 17, and 21 orbs are required to unlock all four additional rows. In addition, +1 more spins are awarded whenever a new row is unlocked, and the grid expansion does not reset throughout the bonus round.
