Theme, Gameplay & Payouts

1st Class Express Big Train Bonus is a video slot from Posh Monkey Studios with 5 reels, 4 rows, and 40 paylines. In the bet selection panel, you can choose your active stake from multiple options, starting from a Min.bet of 0.2 up to a Max.bet of 10. The game's default RTP of 96.01% is on the lower end of the industry average, which typically oscillates around 96.00% - 96.50%. Three alternative variants of 94.01%, 92.01%, and 90.01% are also released, so keep an eye on the version you're playing. The average balance between the size and frequency of wins should favour value due to high volatility, while the top prize from a single spin may reach 25,000x the bet. The base hit frequency sits at the rate of 26.52% for the highest RTP variant.

The main scene of 1st Class Express Big Train Bonus places you before the railroad tracks, with a stone bridge hanging above the passage and two vintage lanterns flanking the path. The omnipresent darkness of the night introduces a mysterious atmosphere and makes the upcoming ride feel pleasantly thrilling. To get on board the luxurious train, you'll need to make some specific moves on the playing grid hovering in the middle, framed in gold. By filling up four coloured cars with gems, you'll be able to secure a ticket and set off on a truly exciting journey. You can experience the ride on any modern device, as the game's universal design adapts seamlessly to any desktop, smartphone, or tablet.

In the paytable, two distinct sets of symbols form the payout hierarchy. To score a win, you need to match at least 3 on any of the active paylines while using neighbouring reels, starting from the left. Among the low-paying icons, you'll recognise playing card ranks: 10, J, Q, K, and A, awarding 1x the bet for a combination of 5 on a payline. Items such as a suitcase, a pocket watch, a vial of perfume, and a golden ticket represent the high-paying symbols, delivering payouts of between 5x and 20x the bet for a complete payline running through all 5 reels. Alongside regular icons, there are also Wilds represented by a gold letter W on a blue tile, Coins with cash prizes, Collectors, and four types of Scatters appearing as coloured gems.

Collect

Landing any number of Coins with instant prizes on reels 1-4 and a Collect symbol on reel 5 awards all their displayed values. Additionally, the total prize may be multiplied by up to x5.

Scatters

Blue, purple, pink, and yellow gems are Scatters, which are collected into their respective colour-matching pots above the reels whenever they land. The blue and yellow ones also have their special versions adorned with a '+' and 'x' symbols, which increase their respective meters. The special blue Scatter provides a +0.5x increase to the Adder Bonus, up to a maximum of 5x the bet, while the yellow Scatter provides a +0.5 increase to the Multi Bonus, up to a maximum of x5. Any combination of Scatters landing during a spin can trigger the Big Train Bonus with the respective upgrades activated.

Blue Scatter = Adder Bonus, adding the displayed value to every carriage and every Coin when the 3x3 Bonus is also active.

Purple Scatter = Mystery Bonus, enabling Mystery carriages and Mystery Symbols if the 3x3 Bonus is also active. Each one reveals a jackpot of 10x (Mini), 20x (Minor), or 100x the bet (Major).

Pink Scatter = 3x3 Bonus, enabling a Carriage with a Hold&Win mini-game played on a 3x3 grid.

Yellow Scatter = Multi Bonus, multiplying each Carriage or Coin when the 3x3 Bonus is also active by the displayed value.

Big Train Bonus

Once awarded, the Big Train Bonus drags Carriages through the screen. Each one contains a cash prize or a Hold&Win mini-game if the round has been triggered with the 3x3 Bonus. A total of 6 to 10 Carriages will roll through the screen, awarding their prizes (between 0.2x and 8x the bet) and jackpots, potentially enhanced by the activated upgrades. If the train brings in all 10 Carriages, you also win the Grand jackpot of 5,000x the bet.

Ante Bet

By toggling the Posh Power option, you can enable or disable the Ante Bet, which changes the game modes. When active, it removes all regular symbols from the reels, leaving only Coins, Scatters, and Collect symbols to play with. Enabling Posh Power costs 5x your base bet.

Final Thoughts on 1st Class Express Big Train Bonus

Experimental games are quite rare among the studios under the Games Global umbrella, so it's nice to see some of the teams trying something slightly different. Posh Monkey Studios didn't showcase a lot of originality with a couple of its first games, but 1st Class Express Big Train Bonus is showing the creators' willingness to branch out, even if the attempt is relatively safe. Some elements are bound to remain, such as plain cash collections in the base game and Hold&Win bonuses, as they have pretty much become a staple under the aggregator in question. Also, the train ride format with gathering cash from individual carriages is not a novelty on its own, having appeared inGold Blitz Express and its several clones and remakes. What's interesting in this production is the way those elements are combined and additionally fused with the pot-trigger mechanics. Plus, everything nicely meshes with the train theme, resulting in a consistent whole between the mechanics and the visuals.

And so, instead of playing a standard Hold&Win bonus and waiting for the Coins to drop and be affected by individual upgrades, you get Carriages rolling through the screen, getting value boosts and multipliers. Some of them can also bring a 3x3 grid where you get to gather up to 9 prizes, also affected by the active upgrades. Some seasoned players can point out that it's pretty much the same thing as scoring Coins on an empty grid, which is true, but here, the presentation does some more lifting than in other slots of the kind, where the theme usually can be absolutely anything. It's not to say that it's in any way groundbreaking and massively innovative, but even after the first playthrough, you can feel that it's not exactly the same Hold&Win thing, even though it probably is when you look at all the math spreadsheets.

1st Class Express Big Train Bonus experiments with a unique presentation of the familiar mechanics based on cash collections, delivering a consistent train-themed game with a clever twist.
