Train of Riches: Capital Express Slot by Evoplay

Two Bonuses, One Train

Train of Riches: Capital Express runs two separate bonus engines on a single 5x3, 25-payline frame. Free Spins strips the reels down to premium symbols. The Hold & Win Bonus Game chases jackpots up to 1,000x. Both paths are purchasable, and a Random Event mechanic acts as a safety net during dry stretches. Evoplay built this one for players who want options without complexity.

Base Game Mechanics

Twenty-five paylines run left to right across five reels. Nine regular symbols split into four premium and five card values. The money bag tops the paytable at 10x your bet for five of a kind - modest even by Hold & Win standards. Safe pays 8x, diamond 6x, gold coin stack 4x. Cards (A through 10) all pay an identical 2x for five.

Wild appears on reels 2 through 5. No reel 1 coverage means you always need a paying symbol on the leftmost position. Scatter sits exclusively on reels 2, 3, and 4.

Free Spins with Filtered Reels

Three Scatters trigger 8 Free Spins. Here's where it gets interesting: the game strips all card values from the reels during the feature. Only Wild, Scatter, Bonus coins, and the four high-value symbols (money bag, safe, diamond, gold stack) remain.

That filtering changes the math significantly. Every spin during the feature has a higher probability of landing premium paying combinations. Three more Scatters during Free Spins award another 8 spins, and the retrigger uses the same filtered reel set. At 23x buy price with a 95.95% RTP, the cost-to-feature ratio sits in reasonable territory for a mid-tier volatility game.

Bonus coins still appear during Free Spins. Land six or more and the Hold & Win round triggers directly from the feature - a nice chain that can stack value from both mechanics in a single sequence.

Hold & Win Bonus Game

Six bonus coins anywhere on the grid - base game or Free Spins - start the Hold & Win round. Each coin carries a random value: 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 10x, 12x, or 14x your bet. Three respins to start, resetting to three on each new coin.

Three jackpots wait at the top. MINI pays 30x, MAJOR 150x, GRAND 1,000x. The GRAND requires filling all 15 positions - every reel cell covered. With coin values ranging up to 14x and 15 possible positions, a full board without the Grand jackpot could theoretically stack around 200x. Add the 1,000x Grand on top and the absolute ceiling hits 1,245x.

At 43x buy price for the Bonus Game directly, the maximum return ratio is about 29:1. Not headline material, but the 95.93% feature RTP keeps the expected value fair for the price.

The Random Event

Evoplay added a rescue mechanic. Any spin that lands at least one Bonus coin but produces no winning combination has a chance to generate five additional Bonus coins on random positions, immediately triggering the Bonus Game with six coins total. The probability isn't published, but it creates a second pathway into the feature beyond natural scatter hits.

The Practical Numbers

RTP at 95.90% sits just under the 96% benchmark. Max win of 1,245x total bet is the ceiling across all features combined. For context: that means a €10 spin maxes out at €12,450. A €0.10 spin caps at €124.50. These aren't numbers that attract big-win hunters.

The strength is in session consistency. Filtered Free Spins deliver above-average hit rates during the feature. The dual buy option lets you target either Free Spins (23x, better for extended play) or the Bonus Game (43x, better for jackpot shots). And the Random Event prevents complete dead zones where Bonus coins tease without triggering.

Visually, the golden locomotive and treasure-themed artwork carry a warm, polished look against the blue mountain backdrop. It's a well-produced game that prioritizes steady returns over dramatic peaks. The 25 paylines and dual-feature structure give it more surface area than Evoplay's 10-payline Hold & Win titles, even if the win cap stays conservative.
