Mustang Money Slot Review: The Complete Ainsworth Family

Every game covered here is built by Ainsworth Game Technology, the Australian studio founded by Len Ainsworth that supplies physical cabinets to casino floors and, through its online arm, licensed slots to regulated US operators. Each Mustang Money title is a video slot dressed in a North American frontier and Wild West theme, with wild mustangs, eagles, campfires, canyons and a stack of Western card values on the reels. The core hook rarely changes: horses that pay and trigger, gold coins that multiply free game wins, and a high paying scatter. What shifts from version to version is the payline count, the volatility, and the exact shape of the bonus.

One clarification belongs at the top, because it is the most common mix up on this family. The plain “Mustang Money” and “Mustang Money 2” you see in free demos are the land based cabinet builds. The versions you can actually load for real money in the regulated US market are Ainsworth’s online adaptations, marketed as Mustang Money Super and Mustang Money Energized for the original, and Mustang Money 2 Energized for the sequel. They share the reels, symbols and bonus of the cabinets, but the online build name and the posted RTP are what you confirm before depositing. This page keeps those straight so you never assume a floor cabinet is the same product as the app version.

Quick-View Table: The Flagship Mustang Money

These headline numbers describe the original Mustang Money, the 100 payline game that started the family, with the online build noted where it differs from the land based cabinet. Where the wider family swings, the value reads “varies by version,” and the detail is broken out further down. Any figure Ainsworth does not publish is marked so, rather than guessed. To understand why the return figure matters before you deposit, our RTP explainer is a useful companion.

Version Comparison Table

This is the fastest way to see how the family splits between the two mainline games and the online adaptations that actually run for real money in the regulated US market. RTP and feature figures come from Ainsworth and from operator information screens where published. Blank or “Not published” cells mean the studio has not released that number, and no figure here is a guess.

Ainsworth has also branched the theme into further cabinet titles, including Mustang Money Super, Mustang Money Money Money and the poultry themed spin-off Mustang Money Raging Roosters, but those sit outside the two mainline games and are covered briefly in the related-titles note near the end rather than presented as core versions.

Game Overview and How Mustang Money Plays

Mustang Money puts you on the open range at dusk. The reels are stacked with wild horses, bald eagles, campfires, a rising sun and a golden dollar sign, all drawn in Ainsworth’s warm, slightly retro cabinet style, with card ranks nine through ace carved in a Western frame to fill out the low end. The original runs five reels and three rows with 100 fixed paylines that pay left to right from the leftmost reel, so a win needs matching symbols on adjacent reels starting at reel one. With 100 lines active the base game hits often but small, which is the rhythm the whole brand is built on.

The base game is deliberately plain, and that is by design. The wild mustang substitutes for everything except the scatter and helps the base reels tick along, but the real money is in the free games, where gold coins land on the middle reels and multiply your wins. Because Mustang Money is a high volatility slot at heart, the base game rarely explodes on its own; it keeps a session alive while you chase three or more scatters. If ways to win math or variance are new to you, the how to play primer walks through line betting, and the volatility guide explains why the swings feel steep on a game with a return this side of 95 percent.

Across the family the loop stays familiar even as the details change. You spin, you bank small line wins, you chase the scatter to open the free games, and once inside you hope the coin multipliers land often and stack. The sequel narrows the grid to 20 lines and swaps the coin multipliers for a held-reel feature, and the modern Energized builds re-skin the original with fiery visuals and a slightly different retrigger, but the base idea of horses that pay and a multiplied bonus never leaves. That consistency is a large part of why the theme has held players for more than a decade on floors and now online.

Symbols and What They Pay

The symbol hierarchy is thematically consistent across the family, which is one reason players move between versions comfortably. From the top of the pay table down, the reels carry the following.

• Wild mustang (wild): The free horse is the wild. It substitutes for every symbol except the scatter to complete winning lines. In the base game of the original it appears across the reels, and in the sequel it is restricted to reels 2, 3 and 4.
• Premium Western icons: The eagle, the campfire, the rising sun and the golden dollar sign are the picture pays that sit above the card ranks and build the bulk of ordinary wins. On the online builds these premiums reach into the hundreds of times the line bet for a full five of a kind.
• Card values: Nine, ten, jack, queen, king and ace fill out the low end as the filler symbols that pay small amounts for three, four or five across the lines.
• Gold coin (feature symbol): A gold coin that appears on reels 2 and 4 during the free games only. It is not a line symbol; its job is to apply a multiplier to wins during the bonus, which is the defining mechanic of the original.
• Mustang Money logo (scatter): The game logo is the scatter and bonus trigger. It pays 2x, 10x or 100x the total bet for three, four or five anywhere on the reels, and it opens the free games.

Because the game does not publish a fixed credit value for every symbol at every bet level, exact per symbol pays are best read from the in game pay table at your chosen stake, where the values scale with the bet. The order of the hierarchy, however, is stable across the mainline titles and their online builds.

Bonus Symbol Cross-Check

Across every version listed on this page, the trigger symbol is the same in spirit, but the mechanics behind it differ enough that you should not assume they behave identically. On the original Mustang Money, Mustang Money Super and Mustang Money Energized, the trigger is the Mustang Money logo scatter, a symbol distinct from the wild horse. Land three or more of the logo scatters and you open the free games. On Mustang Money 2 and Mustang Money 2 Energized, that split is collapsed: the wild horse itself doubles as the scatter and free games trigger, so three flaming mustangs both pay as a scatter and start the round. In short, the original line uses a separate logo scatter, while the sequel line uses the wild horse as its own trigger. That is the single most important symbol difference between the two mainline games, and it changes how you read the reels when you sit down at either one.

How to Trigger the Bonus

Triggering is simple on both mainline games, but the symbol you are watching for is not the same. On the original and its online Super and Energized builds, you land three, four or five Mustang Money logo scatters anywhere on the reels in a single spin. Three scatters award the free games and also pay 2x the total bet, four pay 10x and five pay 100x, so the biggest scatter hit is a meaningful win on its own before the bonus even begins. The standard award is 10 free games regardless of how many scatters landed.

On Mustang Money 2 and its Energized build, the trigger is three of the wild horse symbols landing together, since the horse doubles as the scatter on that game. Three horses award 10 free games. On the original line, retriggering happens when more scatters land during the round, adding spins on top; the Energized build specifically adds 5 extra free games for additional scatters during the feature. There is no bonus buy on any version, so the free games can only be reached by landing the trigger naturally, which rewards patient bankroll play on a high volatility slot. Watching the correct trigger symbol for the version in front of you is the one habit that carries across the whole family.

How the Bonus Works

Once the free games begin, this is where the two mainline games genuinely diverge, so it is worth walking through each.

On the original Mustang Money, and its online Super and Energized forms, the free games play as a straightforward 10 spin round with the gold coin multiplier as the defining twist. During the round, gold coins can land on reels 2 and 4 only. A coin on reel 2 carries a lower multiplier, commonly doubling the win, while a coin on reel 4 carries a larger multiplier of up to 5x. When coins land on both reels in the same winning spin, their multipliers combine, so a single win can be boosted by up to 10x. That multiplier stacking, combined with retriggers that add more spins, is the entire engine behind the original’s biggest bonus runs. On the Energized build the coins are styled as flaming gold coin wilds on the same two reels, and additional scatters during the round add 5 spins each, extending the feature. There is no wheel and no pick round; the drama is purely in how many multiplied coins land while the free games run.

On Mustang Money 2 and Mustang Money 2 Energized, the coin multiplier is replaced by a held-reel feature. When the 10 free games trigger, a special Mustang Money symbol comes into play on reels 1 and 5. Those two outer reels are held and filled entirely with wild mustang symbols for the duration of the feature, while reels 2, 3 and 4 spin between two full walls of horses. Because every win now begins and ends with a stacked wild reel, the round concentrates its winning potential into the middle of the grid and can produce dense, repeated hits across the 20 lines. It is a different feeling from the original’s multiplied coins, trading the coin math for guaranteed wild coverage on both ends of the reels.

Version by Version

Mustang Money (2013)

The original Mustang Money launched on casino floors in 2013 and set the template for everything that followed. It runs five reels and three rows with 100 fixed paylines, a wild mustang that substitutes for all but the scatter, and a Mustang Money logo scatter that pays 2x, 10x or 100x the bet for three, four or five and awards 10 free games. The published RTP on the standard build is 94.38 percent, which sits below the modern 96 percent benchmark, and the volatility is high, with the top payouts concentrated in multiplier heavy bonus runs rather than the base game. Its signature is the gold coin feature: during the free games, coins on reels 2 and 4 multiply wins and combine for up to 10x.

On a casino floor the original is a penny cabinet, playable from 0.01 per line, and Ainsworth has not published a single headline maximum win figure for the cabinet, so that cell is marked rather than guessed. The top scatter pay alone is 100x the bet. For real money online play in the regulated US market, you will not load the bare cabinet software; instead you play one of the online adaptations described next, which keep the reels, symbols and coin bonus intact. The original remains the reference point that every spec on this page is measured against.

Mustang Money Super (online adaptation)

Mustang Money Super is Ainsworth’s online build of the original, and it is the version that carries the classic 100 payline game into browsers and apps. It keeps the five reel, three row layout, the wild mustang, the logo scatter and the gold coin multiplier bonus, and it is the build most often quoted with a high top-end. Its RTP is listed at 94.38 percent on some builds and up to 94.75 percent on others, and its volatility is high. The free games keep the coin multipliers on reels 2 and 4 that combine for up to 10x, and some Super builds present a choice of free spins modes so you can weigh more spins against bigger multipliers.

Super is quoted with a maximum win of up to 10,000 times the stake, the highest ceiling in the family, driven by the multiplied free games rather than any base game line. Bet ranges depend on the operator, commonly running from around 2.00 up to 100 per spin. This is the build to look for if you want the original’s coin bonus with a genuine online top-end, and it plays for real money in regulated lobbies that carry Ainsworth’s catalog.

Mustang Money Energized (2023)

Mustang Money Energized, released in January 2023, is Ainsworth’s modern online reimagining of the original for regulated US operators, and it is the version confirmed live at BetMGM. It gives the frontier theme a fiery makeover, with flame styled visuals over the traditional Western imagery, and it keeps the 100 payline grid, the wild mustang and the logo scatter. The published RTP is 94.38 percent and the volatility is high. The free games are branded the Mustang Money Energized Feature: three or more scatters award 10 spins, and each additional scatter during the round adds 5 more.

The multiplier bonus carries over in energized form as flaming gold coin wilds that land on reels 2 and 4 during the feature, applying random multipliers, a smaller boost on reel 2 and a larger one up to 5x on reel 4. Energized is confirmed at BetMGM across Pennsylvania, New Jersey, West Virginia and Michigan, which makes it the Mustang Money you are most likely to actually load in a legal US app today. It is the online row of the family that a regulated player will meet first.

Mustang Money 2 (2017)

Mustang Money 2 arrived in 2017 and is a genuine redesign rather than a re-skin. It narrows the grid from 100 paylines to 20 fixed lines across the same five reel, three row frame, and it changes the whole feel of the game. Volatility drops to medium, so the base game hits more steadily with a higher frequency of small returns, and the RTP settles at 94.07 percent. The wild mustang now appears only on reels 2, 3 and 4 and doubles as the scatter, so three flaming horses both pay and trigger 10 free games. Card ranks nine through ace, plus premiums such as the eagle and the canyon, fill out the pay table.

The sequel’s headline change is its bonus. When the free games trigger, a Mustang Money symbol comes into play and reels 1 and 5 are held and filled entirely with mustang symbols for the round, while the three middle reels spin between those two stacked wild walls. That concentrates the winning potential and can produce dense repeated hits, a very different sensation from the original’s coin multipliers. The land based and demo Mustang Money 2 is quoted with a maximum win of 1,000 times the stake. For regulated US online play, the sequel appears in its Energized online form described next; the plain build circulates mainly as a free demo.

Mustang Money 2 Energized (online adaptation)

Mustang Money 2 Energized is the online build of the sequel, carrying the 20 payline, medium volatility game into regulated lobbies with the same fiery visual treatment applied to the Energized line. It keeps the five reel, three row layout, the wild mustang restricted to reels 2, 3 and 4 as both wild and scatter, and the held-reel free games where reels 1 and 5 fill with mustangs. The published RTP is 94.09 percent, a hair different from the plain build’s 94.07 percent, reflecting the online configuration, and the maximum win remains 1,000 times the stake.

Because the sequel spreads its 20 lines across a medium volatility model, this is the version for players who prefer more frequent action and a held wild feature over the original’s higher variance coin chase. It plays online in regulated lobbies that carry Ainsworth’s Energized catalog, and it is the sequel’s real money home in the legal US market rather than the plain demo cabinet.

Related Ainsworth Mustang Titles

Ainsworth has extended the theme beyond the two mainline games, and these are worth naming so you can tell them apart, though they sit outside the core family and are not all online in the regulated market. Mustang Money Money Money is a multi-level cabinet variant, and Mustang Money Raging Roosters is a poultry themed spin-off that keeps the coin multiplier structure while swapping the art and adding a fixed jackpot on some builds. These are land based or regional titles rather than the mainline Mustang Money and Mustang Money 2, and where Ainsworth has not published firm specifications for a given cabinet, this page does not invent them. If you have played one of these on a floor and are hunting for it online, the closest regulated online experience is Mustang Money Energized, which shares the coin multiplier core.

Mustang Money on Mobile

Every online Mustang Money build runs in a mobile browser and inside the operator apps, and the Energized versions in particular were built for touch screens rather than simply shrunk. The reels, the spin control and the bet selector scale to a portrait phone screen, the free games and the gold coin multipliers play identically to desktop, and the sequel’s held mustang reels animate cleanly on a handset. Because Mustang Money is a high volatility game on the original line, with long dry stretches punctuated by multiplied bonuses, a stable connection matters; a dropped session mid bonus is handled by the operator’s game state recovery, but it is still worth playing on wifi where you can. Our mobile slots hub covers device compatibility and the operator apps that carry Ainsworth games.

Where to Play Mustang Money

Mustang Money Energized is the Mustang Money you can actually load for real money in the regulated United States, and it lives inside licensed operator apps rather than on any offshore or unlicensed site. To find the current list of vetted, state licensed operators that carry Ainsworth’s catalog, along with the states each one serves and the sign up offers attached, start at the legal casino sites directory and filter to your state. The plain land based cabinets, including Mustang Money Money Money and Mustang Money Raging Roosters, are worth seeking on a physical casino floor if you want the features that have not made the jump to the regulated online market. Always confirm the exact game name and its posted RTP in the live lobby, since the online build and its return can differ from the floor cabinet you remember.
