Every Mustang Money variant has an RTP below the industry average of roughly 96%. That's the first thing you should know. The range across the series runs from 94.07% to 94.75%, which means the house edge is between 5.25% and 5.93% depending on which version you play.
For context: most modern slots from providers like NetEnt, Pragmatic Play, or Play'n Go sit between 95.5% and 96.5%. Ainsworth consistently runs lower across their catalog, not just with Mustang Money. It's a company-wide design choice, probably inherited from their land-based slot roots where lower RTPs are standard.
None of this means you can't win in any given session. RTP is a long-term statistical average. Over 100 spins, your actual return could be 50% or 200% or anything else. Over 100,000 spins, it converges toward the published number. The point is to know what you're signing up for.

What RTP Actually Means for Your Session
People get confused by RTP because they think it applies to individual sessions. It doesn't. RTP is a theoretical average calculated over millions of simulated spins. In a single session of 200 spins, variance dominates everything.
Here's a practical way to think about it. If you bet $5 per spin for 200 spins, you've wagered $1,000 total. At 94.38% RTP, the expected return is $943.80. So mathematically, the slot "costs" you $56.20 for that session. That's the house edge at work.
Compare that to a 96% RTP slot where the same $1,000 in wagers costs you $40. The difference is $16.20 for that session. Over hundreds of sessions, those extra dollars add up. Over a single night, you probably won't notice.
The volatility matters more for how your session feels. High volatility (the original) means long dry spells with occasional big hits. Medium volatility (MM2, Super) means steadier but smaller returns. Both can produce the same RTP over enough spins, but the ride feels very different.
No Variable RTP
One thing in Ainsworth's favor: they don't offer variable RTP settings. Some providers (Pragmatic Play is well known for this) give casinos a menu of RTP options. A slot might be listed as "96.5% RTP" in reviews, but the casino you're playing at chose the 94.5% version. You'd have no way to know without checking the game's help screen, and even that isn't always clear.
Ainsworth doesn't do this. Mustang Money's RTP is the same at every casino. 94.38% is 94.38% whether you play it in Australia, Canada, or New Jersey. It's low, but at least it's honest and consistent.
Mustang Money vs. Competitors
| Slot | Provider | RTP | House Edge |
|---|---|---|---|
| Mustang Gold | Pragmatic Play | 96.53% | 3.47% |
| Dead or Alive 2 | NetEnt | 96.80% | 3.20% |
| Wolf Gold | Pragmatic Play | 96.01% | 3.99% |
| Mustang Money Super | Ainsworth | 94.75% | 5.25% |
| Mustang Money Original | Ainsworth | 94.38% | 5.62% |
| Mustang Money 2 | Ainsworth | 94.07% | 5.93% |
The gap between Mustang Money and its western-themed competitors is about 2 percentage points. That's meaningful over time. Mustang Money compensates with a higher max win (10,000x vs 2,500x for Mustang Gold) and much higher max bet limits, but those are niche advantages most players won't use.
Which Version Should You Pick
If RTP is your primary concern: Mustang Money Super at 94.75%. The difference between it and the worst version (MM2 at 94.07%) is 0.68 percentage points. That translates to about $6.80 per $1,000 wagered. Meaningful if you play frequently, negligible for a single session.
If max win potential matters more than RTP: the original Mustang Money with its 10,000x cap and $10,000 max bet. The RTP is 0.37% lower than Super, but the ceiling is far higher.
If you're strictly comparing Mustang Money to other slots on the market, the RTP puts the whole series at a disadvantage. You play Mustang Money because you like the game's specific mechanics, not because the math favors you.
