Slots Like Almighty Mustang Express: Cash Lock, a Golden Train and a 500x Grand Pot
Almighty Mustang Express is Blueprint Gaming’s Wild West train adventure, running on a fixed 5×3 grid with 20 paylines rather than a cluster or Megaways structure. The game ships with three live RTP configurations, 92%, 93% and 95%, with the top figure the one most UK-facing casinos run, and volatility sits high, built around the Cash Lock hold-and-win bonus and its own Almighty Mustang Express train-building follow-up round. Stakes range from £0.10 to £1,000 a spin, Bonus Spins arrive from three or more scatter symbols, and Blueprint’s own published ceiling is 1,800x the stake, chasing a 500x Grand Cash Pot at the centre of the feature. Anyone browsing slots like Almighty Mustang Express should look for that same locked-grid, tiered-jackpot structure rather than a straightforward free spins round.

How the Game Works

Almighty Mustang Express drops the golden Mustang Express train onto a Wild West backdrop, deep purples and pinks bleeding into the horizon behind five reels of coyotes, eagles and desert cacti. The base game runs on a fixed 5×3 grid and 20 set paylines rather than the ways or cluster structures Blueprint has used elsewhere, so the paytable behaves like a classic line-pay slot even though the bonus mechanics underneath it are anything but classic.
What separates it from a standard line-pay release is the Cash Prize economy sitting behind every spin. Landing six or more Cash Prize symbols anywhere in view locks the Cash Lock feature into motion, holding those symbols in place and handing three respins to fill the rest of the 15-position grid with more prizes, Cash Pot symbols or a Train symbol. Any new qualifying symbol resets the counter back to three, so a lucky run can stretch a long way before the round finally settles.
Landing a Train symbol during Cash Lock does more than add a value, it carries the round into the Almighty Mustang Express Feature, where the player starts building a train of their own. Filling the ten carriage positions with more Cash Prize and Cash Pot symbols pays out the round’s Grand Cash Pot, while landing another Train symbol along the way adds an extra carriage and keeps the sequence alive rather than ending it.
Symbols and Paytable
The top-paying symbols follow the Wild West theme directly. A gold bell, an eagle, a coyote and a desert cactus carry the biggest line wins, each worth between 5x and 15x the stake for five of a kind. A black Mustang head works as the game’s Wild, substituting for any of those symbols and matching the bell’s payout when it completes a line of its own. Card royals, King, Queen and Ace, fill out the lower end of the paytable at 1x to 3x. Cash Prize symbols pay their own printed value directly, from 1x up to 15x the stake in the base game, rising to a 5x to 50x range once the Cash Lock feature is running.
Bonus Features Explained
The Cash Lock Feature
Six or more Cash Prize symbols landing anywhere in view triggers Cash Lock. The grid locks in place and the player gets three respins to fill the remaining positions, with Cash Prize, Cash Pot or Train symbols all eligible to land. Every fresh symbol resets the counter to three, so the round can run for a while if the spins keep landing, and it ends only once three respins pass without a new addition.
The Almighty Mustang Express Feature
Landing a Train symbol during Cash Lock moves the round into the Almighty Mustang Express Feature. Here the goal shifts to filling all ten positions on the train with Cash Prize or Cash Pot symbols, which pays out the Grand Cash Pot in full. Landing another Train symbol instead of a value symbol adds a fresh carriage to the train and keeps the respins going, so the feature can run considerably longer than the base Cash Lock round it grew out of.
Train Collector
Train Collector is Blueprint’s name for a random modifier that can strike on any spin, main game or bonus. It adds at least two extra Cash Prize or Cash Pot symbols directly onto the reels outside of any feature, occasionally with a Train symbol alongside them, giving the base game a chance at nudging straight into Cash Lock even on a spin that looked ordinary.
Bonus Spins Feature
Three, four or five Bonus scatter symbols landing anywhere in view award 6, 8 or 10 Bonus Spins respectively. The round switches to a different reel set stocked with high-value symbols, Wilds, Cash Prize and Cash Pot symbols, and any Wild that lands during the spins expands to cover its entire reel. Cash Lock can still trigger inside Bonus Spins, so a well-timed six-symbol landing can chain the two features together.
Express Bet
Express Bet raises the cost of a spin to 1.5x the base stake in exchange for a better chance of triggering Cash Lock. It is a common Blueprint side bet format, though it is not available to players at UK-licensed casinos, so most readers here will only ever see the standard-cost spin.
Pros and Cons
Pros
- The Cash Lock feature can chain straight into the Almighty Mustang Express Feature, giving two separate shots at the Grand Cash Pot inside one bonus sequence
- Train Collector can nudge a completely ordinary base-game spin into the bonus without needing a big scatter landing
- Three tiered Cash Pot values, Minor at 25x, Major at 100x and Grand at 500x, give the hold-and-win round layered targets rather than one flat prize
- A fixed 5×3 grid and 20 set paylines keep the base paytable easy to read next to Blueprint’s more complex ways-pays releases
- Bonus Spins swaps in a wilds-heavy reel set with full-reel expanding Wilds, a genuinely different spin from the Cash Lock side of the game
Cons
- High volatility means long runs without a Cash Prize symbol in sight are common
- Blueprint runs three separate RTP configurations, 92%, 93% and 95%, so it is worth checking which version a casino has live before playing
- Blueprint’s own published max win of 1,800x the stake is modest for a Hold and Win release, though a few third-party trackers list a considerably higher 5,000x ceiling instead
- Express Bet, the quickest route to Cash Lock, is not offered to UK players
- The overall hold-and-win-into-bonus-round shape will feel familiar to anyone who has already played Blueprint’s earlier Cash-branded titles

Expert Take
Almighty Mustang Express earns its keep by giving a familiar Hold and Win shape a genuine second act. Plenty of cash-collector slots stop once the respins run out, but sending a lucky Train symbol into a dedicated train-building round, with its own Grand Cash Pot and the chance to add extra carriages, gives the format somewhere to go that most rivals don’t bother with. The trade-off is a max win that Blueprint itself only rates at 1,800x, modest next to the game’s high-volatility billing, and three different RTP configurations mean the version a player actually gets depends entirely on which casino they are sat at.
Similar Slots to Try
The picks below run from the closest Wild West cousins to other train and hold-and-win rides with a similar high-volatility feel.
Pragmatic Play’s own Wild West Hold & Win release trades the train-building follow-up round for a single-tier jackpot, but the six-symbol money respin trigger feels immediately familiar.
A closer thematic match than most, since it puts a runaway train and a posse of outlaws through its own Hold & Win style bonus rather than a carriage-building round.
Another locomotive theme entirely, built around a straightforward gold-rush free spins structure instead of a locked-grid respin feature, worth a look for the shared setting alone.
Swaps the steam engine for a desert chase on horseback, with its own take on Wild West bonus rounds for readers who want the setting without the Cash Lock mechanic.
About the Developer
Blueprint Gaming is a UK-based studio and a wholly owned subsidiary of the Merkur Group, supplying slots to online, mobile and land-based casinos across multiple regulated markets. The studio’s reputation was built on titles like Fishin’ Frenzy and the wider King Kong Cash and Genie Jackpots families, and Almighty Mustang Express continues its long-running interest in hold-and-win formats, layering a second bonus round on top of the standard Cash Lock respin sequence rather than leaving the feature to end after one set of prizes.
A newer Blueprint release built around its own treasure-hunting bonus round, a useful comparison for how the studio varies its hold-and-win structures between licences.
A calmer, lower-volatility Blueprint classic that swaps Cash Lock for a straightforward gamble feature, a gentler entry point into the studio’s back catalogue.
Part of Blueprint’s long-running Cash series, this one runs on jackpot wheels rather than a locked-grid respin, a reminder of how differently the studio’s Cash titles can play.
Blueprint’s best-known release and the game most players will already recognise, useful context for how far the studio’s range stretches beyond Wild West hold-and-win slots like this one.

Cash Pot and Hold and Win Mechanics
Both of these lean on the same locked-grid, tiered-jackpot idea that drives Cash Lock here.
Another train-themed Hold & Win release, with its own take on a six-symbol respin trigger and a single jackpot tier rather than a two-stage structure.
Trades the Wild West setting for a gentler countryside theme, but keeps the same idea of stacked Cash Pot tiers building toward one big collect.
High-Volatility Western Adventures
For readers who want the setting without the specific mechanic, these two carry a similarly high-risk profile.
A lighter, more cartoonish take on the outlaw-train theme, with its own bonus round standing in for a Cash Lock style respin sequence.
A straightforward Wild West line-pay slot without a hold-and-win mechanic at all, a useful baseline for comparing how much Cash Lock adds to the formula.
Frequently Asked Questions
How does the Cash Lock feature work in Almighty Mustang Express?
Landing six or more Cash Prize symbols anywhere in view locks those symbols in place and starts three respins. Any new Cash Prize, Cash Pot or Train symbol resets the counter back to three, and landing a Train symbol carries the round into the Almighty Mustang Express Feature instead of ending it there.
What is the RTP of Almighty Mustang Express?
Blueprint Gaming runs three live configurations, 92%, 93% and 95%, with 95% the one most UK-facing casinos use. It is worth checking the exact figure shown in a casino’s own game information before playing.
What is the maximum win on Almighty Mustang Express?
Blueprint Gaming’s own published ceiling is 1,800x the stake, reached by filling the Almighty Mustang Express Feature’s train and collecting the 500x Grand Cash Pot. A handful of third-party trackers list a higher 5,000x figure instead, so treat the top end as a rare outcome either way.
How volatile is Almighty Mustang Express?
It is rated high volatility. Cash Prize symbols need to gather in numbers before Cash Lock even triggers, so sessions can run for a while between meaningful bonus rounds.
What are the best slots like Almighty Mustang Express?
Other Wild West or train-themed Hold and Win releases with a locked-grid respin mechanic give the closest comparison, rather than games that only share the cowboy artwork.
Can I play Almighty Mustang Express for free?
Yes, the demo embedded above runs the same reel set and features as the real-money version, no sign-up needed.
Who developed Almighty Mustang Express?
Blueprint Gaming, a UK-based studio owned by the Merkur Group, released the game on 9 October 2025.
Our Verdict on Almighty Mustang Express
Almighty Mustang Express is worth a spin for anyone who likes their Hold and Win bonus to keep going rather than stop after one set of respins. Sending a lucky Train symbol into the Almighty Mustang Express Feature, with its own carriage-building respins and a genuine shot at the 500x Grand Cash Pot, gives the format a second act that plenty of cash-collector slots skip entirely. It will not suit players chasing a huge published ceiling, Blueprint’s own 1,800x figure is modest for the genre, and the three different RTP configurations mean it pays to check which version is actually live before betting. For a well-built take on a familiar mechanic, though, it holds up.
