Mustangs and Stallions

The Black Stallion Wild in Mustangs and Stallions does not just substitute: it expands to fill an entire reel, then walks left one position on each respin it triggers, locking in place until it exits the grid. Booming Games built this 5x3 high volatility slot with 20 paylines, a 95.4% RTP, and a 4,000x top win, putting the walking wild mechanic at the center of most of the game's biggest wins. Available on desktop and mobile with crypto at Wild.io.

What is Mustangs and Stallions?

Mustangs and Stallions is a 5x3 video slot from Booming Games with a 95.4% RTP, high volatility, and a top win of 4,000x your bet. Its standout mechanic is an expanding Black Stallion Wild that triggers walking wild respins, moving left one reel per respin while a multiplier of up to 10x builds with each step.

The game runs on 20 paylines using a clean American West setting. Free spins activate with three or more Setting Sun Scatters, awarding 9, 12, or 15 spins depending on how many land. During the bonus round the walking wild carries into free spins, and the win multiplier accumulates across each wild step rather than resetting. The 28.7% hit frequency reflects the high volatility profile: regular spins deliver wins less than a third of the time, but when the stallion locks and walks across the grid the multiplier effect pulls the session value upward quickly.

How To Play Mustangs and Stallions Slot - Step By Step

Head to Wild.io and create a free account to start playing Mustangs and Stallions.

1. Set your bet and spin the 5 reels across the 20-payline grid.
2. Watch for the Black Stallion Wild on any reel: when it lands, it expands to cover the full reel height, then locks in place and triggers walking wild respins.
3. Each respin shifts the expanded stallion wild one reel to the left. The win multiplier increases with each step, reaching up to 10x by the time the wild walks off the left edge of the grid.
4. If three or more Setting Sun Scatter symbols land anywhere on the reels, you enter the free spins round. Three scatters give 9 spins, four give 12, and five give 15.
5. During free spins, the walking wild mechanic remains active. The accumulated multiplier does not reset between spins, so a stallion that walks multiple steps builds the multiplier further into the bonus round.

Mustangs and Stallions Slot Theme & Graphics

Mustangs and Stallions frames the American Great Plains as a backdrop for high-drama horse imagery. The reels sit against a wide open sky with rolling grassland in the distance. The white and brown horse symbols are illustrated with detail, each posed in motion rather than static. The Black Stallion Wild is the largest and most detailed symbol, drawn with muscular definition and a windswept mane that fills the expanded reel when the wild activates.

The sound design uses a steady country-influenced score that shifts tempo when the walking wild respin triggers. The setting sun scatter is the warmest visual on the grid, its orange glow contrasting with the cooler tones of the card rank symbols. On mobile the expanding wild animation scales clearly even on smaller screens, and the horseshoe and hat premium symbols remain distinguishable at reduced sizes. Players who enjoy the wild-west theme category of slots will find Mustangs and Stallions fits neatly alongside other entries in that genre.

Mustangs and Stallions Slot Symbols & Paytables

Mustangs and Stallions uses a two-tier symbol set with themed premiums above the card ranks, plus a distinct wild and scatter that each carry mechanical roles beyond basic substitution.

Special Symbols

The Black Stallion is the wild: it expands on landing to cover the full reel, then triggers walking wild respins that shift it one position left per spin with a building win multiplier up to 10x. The Setting Sun is the scatter, paying a cash prize for five anywhere on the screen and triggering 9, 12, or 15 free spins for 3, 4, or 5 symbols. During free spins the multiplier does not reset, carrying the accumulated value from one walking wild activation to the next.

Mustangs and Stallions Bonus Feature & Special Features

Expanding Wild and Walking Wilds Respins

When the Black Stallion Wild lands on any reel, it immediately expands to fill all three rows of that reel. The expanded wild then locks in place and triggers walking wild respins. On each respin it shifts one position to the left, remaining locked and participating in every payline that crosses it. A win multiplier activates at the start of the first respin and increases with each subsequent step, reaching a maximum of 10x. The walking respin ends when the stallion moves off the left edge of the grid, or when no winning combination forms on the current respin step. A stallion landing on reel 5 can walk through all five positions during respins, accumulating the full multiplier progression. In the free spins round the multiplier carries across wild activations rather than resetting, creating the conditions for the game's 4,000x top win.

Free Spins

Three, four, or five Setting Sun Scatter symbols anywhere on the 5x3 grid award 9, 12, or 15 free spins respectively. The walking wild mechanic is fully active throughout the feature. When the Black Stallion appears during a free spin, it expands and walks left through respins exactly as in the base game, but the accumulated multiplier persists across multiple wild activations within the bonus round rather than resetting after each one. This means a second or third stallion landing during the same free spins session builds on the multiplier already established, potentially combining a late-feature wild with a 10x multiplier for the game's highest payout tier. The scatter cannot retrigger the free spins from within the feature.
