Understanding the Train of Gold Demo Gameplay

The Train of Gold slot game operates on a 5-reel, 3-row layout. The base game is straightforward, focusing on lining up symbols from left to right. It’s an ideal setup for a free play session, as you can quickly understand the flow.

Symbols and Payouts: From Fruits to WILDS

The paytable is a nod to vintage fruit-themed slots. You'll find Cherries, Lemons, Oranges, and Watermelons as the low-pay symbols, all offering 10x the bet for a 5-of-a-kind line. Moving up, the Grapes and BAR symbols pay 25x. The premium symbols are the Horseshoe and the Bell, each paying 50x for a full line. This simple, easy-to-read paytable means you're never guessing what a win is worth. Many Bell-themed games follow this classic payout structure.

What is the Wild Symbol?

The “77 WILD” symbol is the most valuable regular symbol in the game. It can appear on any reel and substitutes for all other symbols except the Special and Bonus icons. A full line of five Wilds pays 75x your bet. In a game with relatively few pay symbols, the Wild's appearance is a significant event, often connecting multiple wins at once, much like in other Sevens-themed slots such as Super 7 Winner.

How to Trigger the Bonus Game in Train of Gold

This is the most important part of the game. The entire experience is built around activating the Collect Feature. There are two main ways to do this: manually or by buying it.

The Core Trigger: The Coin Game Explained

To enter the bonus, you need to trigger the Coin Game. This isn't a typical 3-scatter trigger. Instead, you must land Coin symbols (which show cash values) on reels 1, 2, 4, and 5, and land the Special “Train” symbol on the central 3rd reel, all on the same spin.

The Train symbol only appears on that central reel, making it the “trigger reel” you'll be watching constantly.

The Collect Feature: A Central Collector Hold & Win

Once triggered, you enter the Collect Feature. This is a Hold & Win bonus round. The regular symbols disappear, and the grid spins with only Coin symbols and blanks. However, it has a fantastic twist.

Instead of coins just sticking in place, when a Coin lands anywhere, its value “flies” to the central Train symbol on reel 3 and is added to a growing pot. The coin also remains on the reel for the rest of the feature. This means you are “double-dipping”—the coins stick, and their values are also instantly collected. This central collector mechanic is a refreshing change from standard Hold & Win games like Crown Strike: Hold and Win and adds a clear focal point to the bonus. It's all about feeding that train.

Vlad Hvalov's Expert Take:

I've seen hundreds of Hold & Win games. The central collector train in this one is an interesting twist. Instead of just filling the screen, you're feeding a single, growing pot. It changes the psychology of the bonus round completely. You're not just hoping to fill cells; you're hoping for high-value coins to feed the engine.

What is the Lucky Choo Choo Feature?

During the Collect Feature, a new symbol can appear: the “Special Coin.” This coin (a golden circle with a train emblem) activates the Lucky Choo Choo Feature. The game's info screen describes this as a modifier that appears only during the bonus. While its exact action isn't detailed, in money-themed slots like this, such features often involve multipliers, collecting all visible values again, or adding extra spins. Discovering what it does is a key part of the excitement in the demo.

Jackpot Bonus: Chasing the Grand Prize

You can't miss the four Jackpot values displayed on the left of the screen. The Train of Gold game features four fixed jackpots, which are key to its gold-themed appeal.

How to Win the Mini, Minor, Major, and Grand Jackpots

These jackpots are not won via symbol lines. Instead, they are tied to the Collect Feature. During the bonus round, special Coins can land displaying the words MINI, MINOR, MAJOR, or GRAND instead of a cash value. When these land, you win that corresponding prize.

The values are fixed multipliers of your total bet:

• Mini: 25x Bet
• Minor: 50x Bet
• Major: 150x Bet
• Grand: 1,000x Bet

Landing one of these jackpot coins is a high-impact moment, similar to the jackpot mechanics in Cash Strike Power 5.

Accelerating Your Demo Session: Bonus Buy & Bonus Chance

For players testing the Train of Gold free play demo, waiting for the precise Coin Game trigger can take time. Onlyplay has included two features to speed things up.

What is the Bonus Chance Bet?

You can activate the “Bonus Chance” feature from the main screen. This is an ante bet. It increases your total bet cost by 1.5x (e.g., a 0.50 bet becomes 0.75). In exchange, your chances of naturally triggering the Collect Feature are increased. It's a trade-off: higher cost per spin for more frequent bonus action.

Using the Bonus Buy Feature

If you want to skip the base game entirely, you can use the Bonus Buy. For a one-time payment of 70x your base bet, you will instantly trigger the Collect Feature.

Vlad Hvalov's Expert Take:

Honestly, the 70x Bonus Buy is priced quite reasonably. In the Train of Gold demo, this is your best tool. Use it to skip the base game grind and directly analyze the Collect Feature's potential. Don't just buy it once; test it 10-20 times to get a real feel for its payout distribution.

A Note on Self-Control:

A word of caution on that 70x buy. It's tempting, but it can drain a demo balance in seconds. My advice? Set a rule before you start. For instance, “I will only use the Bonus Buy five times,” or “I will only use it if my balance is above the starting 10,000.” Practice that discipline here, for free.

Hidden Synergy: The Trigger Mechanism

The real synergy here isn't just “coins + train.” It's the deliberate design of how they interact. The Special Train symbol is only on reel 3. The triggering Coins are only on reels 1, 2, 4, and 5. This design forces you to watch the entire screen at once. It's a clever way to make the 5×3 grid feel more interconnected. Then, the second special symbol (the “Special Coin” for the Choo Choo feature) only appears after this trigger. It's a chain reaction: the base game is 100% focused on unlocking the bonus, and the bonus then reveals another layer of features.

What If… The Collector Train Moved?

Here’s a thought. What if that central Train collector wasn't static on reel 3 during the bonus? What if, on each respin, it moved to a random reel? One spin it's on reel 1, the next on reel 4. This would completely change your anticipation. You wouldn't just be hoping for coins to land anywhere; you'd be hoping for them to land near the train's new position. It would add a fantastic layer of chase and volatility to the bonus round. Just an idea.

All Aboard the Details: Deeper Insights

Here are a few details you might miss on your first few spins of the demo:

1. Wild Pays Best: The “77 WILD” is the highest-paying symbol in the game at 75x. This is more than the top-tier Bell and Horseshoe symbols (50x). Always watch for those 7s.
2. Reel 3 is Key: The Special Train symbol only appearing on the central reel makes it the single most important piece of visual real estate in the base game.
3. Ante Bet Cost: The “Bonus Chance” ante bet costs 1.5x. This is a higher premium than the 1.2x or 1.25x seen in many other slots, which suggests the bonus game is mathematically where the vast majority of the game's payout is concentrated.

Games Similar to Train of Gold: Hold & Win

If you enjoy the demo, you might want to explore other similar titles.

• For the Train Theme: The Trains theme is always popular. For another take on it, check out Almighty Mustang Express. For a very different journey, the zombie-themed Train to Seoul is a wild ride.
• For the Coin Collect Mechanic: If you like the Hold & Win and coin collection, Sun of Egypt 3 is a classic example of the genre. For simpler, direct coin games, Money Coming is a great comparison.
• For the Classic Fruit Style: This game's base visuals are pure classic. For more of that, you can't go wrong with Fruit Shop from NetEnt or the ultra-clean Wild Fruits 27.

So, what's the final ticket?

The Train of Gold: Hold & Win slot is a solid, focused game. It knows exactly what it wants to be. It's not a revolutionary title, but its one big idea—the central collector train—is a good one, and it executes it cleanly. It makes the Hold & Win bonus feel more interactive, as you're actively “feeding” the pot instead of just watching cells fill up.

This feels very much like an Onlyplay game: clean graphics, a mobile-first UI, and a strong emphasis on a single, compelling bonus mechanic. It doesn't have deep narrative or complex layers, but it doesn't need them. It's built for players who like classic visuals but want the modern jackpot-chasing thrill. For a demo session, especially using the Bonus Buy, it’s a great way to experience a fun twist on a familiar feature. I'd say it's definitely worth a few spins.
