Money Train (Relax Gaming) Slot Review

Money Train: Slot Overview
Money Train is a Wild West-themed train heist video slot developed by Relax Gaming and released on 2019-08-07. It features a 5-reel, 4-row grid with 40 fixed paylines, where wins form by landing three or more matching symbols starting from the leftmost reel. The game emphasizes high-volatility gameplay centered around a respins-style bonus round with special symbols that enhance potential payouts, culminating in a maximum win of 20,000x the bet. Stacked symbols appear in the base game, contributing to frequent hits at an 18.73% hit frequency. This slot targets experienced players who enjoy high-risk, high-reward mechanics, bonus buys, and immersive thematic adventures rather than low-volatility, frequent small wins.
Design and Graphics
The visual design immerses players in a gritty Wild West setting, with the play area framed inside a red train car that animates by rolling in from the right side of the screen upon loading. Flanking the reels are rustic brown wooden houses typical of a cowboy town, set against dusty train tracks below. The color palette blends earthy tones—browns, reds, and golds—with vibrant accents on symbols for readability. Symbols include low-paying playing card suits (diamonds, clubs, hearts, spades) rendered in wooden textures, and high-paying characters: a woman in a blue hat, a green-dressed man, a Native American figure, and a gray-haired man in a suit. These premium symbols reappear in the bonus with bandanas covering faces, tying into the heist theme.

Money Train slot – base game
Animations are smooth and thematic: reels spin within the train car, wins trigger subtle explosions and glows, and special symbols in the bonus reveal values with flair. The Wild symbol, depicted as crossed rifles, integrates seamlessly. Audio enhances the atmosphere with an upbeat spaghetti western soundtrack featuring melodic guitars and groovy cowboy rhythms, looping effectively without overwhelming gameplay. The interface places controls below the tracks for intuitive access, including spin, autoplay, and bet adjustment buttons. Optimized for mobile and desktop via HTML5, the game maintains crisp graphics across devices, with no reported lag in transitions. Overall, the aesthetic is polished and cohesive, prioritizing thematic immersion over flashy excess.
Gameplay Mechanics
Money Train operates on a 5×4 grid with 40 fixed paylines, where winning combinations require three or more identical symbols aligning from left to right on active lines. All regular symbols, including the Wild, appear fully stacked on reels, increasing the likelihood of multi-line wins. The base game flows straightforwardly: set bets from 0.10 to 50 per spin, hit spin or autoplay (up to 1,000 spins with customizable limits), and watch reels tumble to form pays. Payouts are calculated as multiples of the total bet, with low-paying card suits delivering 0.75x to 1.25x for five-of-a-kind, and premiums up to 5x.
The Wild symbol (crossed rifles) substitutes for all standard pay symbols but not Scatters or bonus specials, aiding line wins without additional modifiers in the base. No free spins or base game extras exist beyond stacking, keeping focus on triggering the main feature. Hit frequency stands at 18.73%, equating to a win roughly every fifth spin on average.
| Symbol | 3-of-a-Kind | 4-of-a-Kind | 5-of-a-Kind |
|---|---|---|---|
| Diamonds / Clubs / Hearts / Spades | 0.4x | 1x | 3x – 5x |
| Woman in Blue Hat | 0.6x | 2x | 8x |
| Green-Dressed Man | 0.8x | 3x | 10x |
| Native American | 1x | 4x | 15x |
| Gray-Haired Man | 1.2x | 5x | 20x |
Bonus Features
The core attraction is the Money Cart Bonus Round, triggered by landing three Scatter symbols simultaneously on reels 1, 3, and 5 (frequency: 1 in 297.5 spins). This transports players to a new 5×4 train car grid with 20 individual positions. Triggering Scatters lock in place, each revealing a random multiplier value (as x bet). Players start with 3 respins; any new symbol landing (Scatter, cash, or special) resets the counter to 3. The round ends when spins reach zero, the grid fills, or 20,000x max win is hit.
Symbols in the bonus include:
- Money Safe: Reveals a cash value (x bet), pays at end.
- Payer (female robber): Reveals value, adds it to all other visible money symbols.
- Persistent Payer: Like Payer, but applies its value to others on landing spin and all subsequent spins (ignores self).
- Collector: Reveals value, then gathers all visible cash values and adds to its own.
- Persistent Collector: Like Collector, but gathers values at end of its spin and every following spin (ignores self).
- Widener: Reveals value, expands grid by one reel (up to two extras, one per side), increasing positions to 24 max.
- Tumbleweed: Blank, no value, no reset.

All values pay at round’s end. Total awards can escalate dramatically via synergies, e.g., Persistent symbols compounding over respins. A recorded example hit 8,248x.
Bonus Buy option instantly activates the Money Cart Bonus Round for 80x the bet, boosting RTP to 98% (base RTP: 96.2%). No other bonuses exist, concentrating excitement here.
Betting Options and Payouts
Betting ranges from a minimum of 0.10 to a maximum of 50 per spin, accommodating casual and high-roller play. The RTP is 96.2% in the base game, rising to 98% via Bonus Buy. Volatility is high, suiting players chasing large but infrequent payouts, with bonus frequency at 1 in 297.5 spins and average bonus win around 78.4x the bet. Maximum win potential reaches 20,000x the stake, achievable solely in the Money Cart Bonus Round (probability not specified). Payouts behave erratically due to stacking and respins, with base game wins modest (up to 20x) but bonuses capable of extreme multipliers.
