Enhancing the slot’s gameplay are two special features that can give you extra chances to win. To find out how each of them works, read the summaries below.
The wild symbol can expand to fill the reel it is on. Whenever it does this, the Walking Wilds respin feature starts. You start with a 1x multiplier and the expanded wild moves one position to the left with every respin. The multiplier also increases with each respin and its values are 2x, 3x, 5x and 7x. Once it reaches 7x, it will not go any higher. While using respins, extra wilds can appear and expand, potentially making the feature last longer. It only ends when there are no more expanded wilds on the grid.

Whenever three, four or five scatters appear, you earn nine, 12 or 15 free spins respectively. There is an expanded wild that moves to a different reel on every spin. Each reel comes with a random multiplier of up to 10x that changes whenever you spin the reels. If you win with the wild, the reel’s multiplier applies to your payout. Scatters do not appear in the free spins round, so unfortunately it is not possible to earn extra spins.

Mustangs and Stallions is one of many online slots that draw inspiration from the Wild West. The focus is not on cowboys and outlaws, with the slot instead shining the spotlight on the West’s scenic landscapes and wildlife. The slot certainly looks appealing, and its gameplay is sure to satisfy players thanks to its features, namely expanding wilds that trigger respins and free spins. The slot’s maximum payout of 4,000x is decent, though its RTP of 95.4% is lower than average. As its volatility is high, you may not win too often, though big payouts can come along every now and then.
