It’s impossible to be a customer of US slots casinos without having rubbed your fingers over a screen to play a title from Play’n GO. Its new train-themed digital slot, Bullion Xpress, has impressed me.

The action unfolds on a 6×3 grid with 10 fixed paylines. This medium-high volatility ride features a generous RTP of 96.29% with wagers ranging from just 0.10 to 100 credits per spin.

Stylized card icons act as the low pays, offering 3x to 5x your stake. The real treasure comes from premium symbols like rings, gold piles, and safes, which award a lucrative 25x to 100x for a full line.

How Wild Symbols Work in Bullion Xpress

Wild symbols can appear on any reel to help secure a win. They stand in for all regular paying icons, substituting to complete combinations, but they will not replace the valuable scatter symbols.

M-Counter

What is an M Counter? Just think of it as a tally of all the multipliers you accumulate.

On Bullion Xpress, each multiplier is worth between x2 to x25. The more multipliers you have, the better your multiplier bonus could be. Note that the M-Counter will reset at the conclusion of each round.

Bonus Blitz

The main objective in the Bonus Blitz is creating valuable bullions. Align multiplier symbols on the bottom row with the railcar symbols directly above them. A successful alignment multiplies the railcar’s value, and the resulting prize is collected.

The Bonus Blitz feature plays out on a special 8×2 grid. With each respin, the top row of railcars moves left to right. At the same time, the bottom row of multipliers scrolls in the opposite direction from right to left.

Railcar values range from 1x to 18x across Bronze, Silver, and Gold types. Mystery cars offer a potential of 4x to 16x. The multipliers that can appear below them are x1, x2, x3, and x5.

You can extend the bonus by aligning a multiplier with a special Respin railcar. The value of the multiplier determines how many extra spins you receive. A maximum of 20 respins can be accumulated during the feature.

To trigger the round, land 3 or 4 scatters on the four middle reels. This grants an initial 3 or 4 respins, respectively, to begin your bonus. Game playing note: scatters do not appear on the first or last reel.

Fortune Frenzy

A unique feature of Bullion Xpress is the window running above the reel area. It’s a train running from left to right. This feature can trigger a bonus called Fortune Frenzy.

Even if your spin gives you no wins, the Fortune Frenzy can be triggered, which grants you the winning values from four cars rolling on the track. Earn between 1x and 12x from those cars depending on their color: bronze, silver, gold, and mystery.

Note: if you get a multiplier in the same round as a Fortune Frenzy, your win is multiplied by the M Counter value.

Slot Rating from Our Expert

After some time figuring out the M Counter and the bonus and reel payout rules, I finally got the knack for Bullion Xpress. However, it took a little longer than I liked to learn this title.

But I was glad I did once I started to devote time to playing this Play’n GO slot casino game. There are frequent multipliers to break up the monotony, and the M Counter, while a novelty, is good fun.

My favorite feature in the game is the Feature Frenzy, because it can literally pop up at any time.
