Almighty Mustang Express Slot by Blueprint Gaming

The reels sit inside a brass-and-gold cabinet against a magenta desert sunset, with a chrome locomotive front gleaming in the lower-left corner and an ornate "Almighty Mustang Express" wordmark on a black scrollwork banner up top. Card royals in cowboy-stencil fonts mix with cactus, gold bell, raven, and mountain lion icons, while bright orange Cash Prize fireballs land with values like 1.00, 1.50, or 3.00 burned across their faces. The mustang horse is the Wild.

This is Blueprint's Cash Lock format wrapped in Wild West dressing, and the trigger threshold is steeper than usual. You need 6 or more Cash Prize or Cash Pot scatters in view at once, or 5 scatters plus a Train symbol, to open the Cash Feature. From there it's the familiar respin loop: 3 spins to start, any non-blank symbol locks and resets the counter back to 3, and the round ends when three consecutive spins land nothing new. The payout is the sum of every cash value held on screen. Two of the three pots at the top of the reels, MINOR at 25x and MAJOR at 100x, drop in as scatter values. The GRAND at 500x isn't a symbol at all, it pays only if you fill every position with non-blank tiles.

Where it gets generous is the chain. If a Train symbol is in view when the Cash Feature ends, you roll straight into the Almighty Mustang Express Feature: a 10-position board where cash values jump from the base 1-15x ladder to a 5-50x ladder. Same 3-spin reset mechanic, same fill-the-grid GRAND rule, but now retriggerable up to five total times per round if the Train keeps showing up at the end. Five chained features with a 50x cash ceiling is the engine cap on this game, and it tops out at 1,800x the bet (any 5,000x figure floating around marketing is inflated).

The Train Collector mechanic runs in the background of every base spin. The locomotive can dump extra cash symbols onto the reels, sneak in a Train, drop wilds, or add Bonus scatters, and at the end of a spin it can outright shoot cash onto the grid to guarantee a feature entry. Bonus Spins are a separate path, 3, 4, or 5 scatters award 6, 8, or 10 spins on a different reel set where wilds land stacked and expand to cover the whole reel they hit on. Hit the Cash Feature trigger during Bonus Spins and it plays out fully before you return to your remaining count.

No buy bonus here. Instead there's Express Bet, a 0.5x ante toggle that lifts the Cash Feature trigger odds while leaving payouts on the unboosted stake. The 5-retrigger ceiling alone makes this one of Blueprint's more aggressive Cash Lock builds, even if the engine cap keeps the headline number grounded.
