Coin Express

Coin Express by 3 Oaks is a 5x3 Hold & Win slot that wraps classic fruit-machine imagery around a gold train theme. The reels carry cherries, bells, and lucky sevens, but the real journey starts when the bonus coin symbols fill the track and the four fixed jackpots come into view. With medium-high volatility and a 5,000x max win, it suits players who want familiar symbols paired with a modern respin mechanic. The game runs on desktop and mobile, and crypto deposits are fully supported at Wild.io.

What is Coin Express?

Coin Express is a 5x3 video slot from 3 Oaks Gaming with a 95.69% RTP, medium-high volatility, and a top prize of 5,000x your bet via the Grand Jackpot. The standout mechanic is a Hold and Win bonus where coin symbols lock on the reels and trigger respins until no new coins land or the grid fills.

Beyond the base game, Coin Express keeps the structure lean: five paylines across three rows, a wild symbol that fills gaps in winning combinations, and a bonus coin mechanic that does most of the heavy lifting. The hit frequency sits at 11.48%, which means wins come less often in regular play but the bonus game concentrates the bigger payouts into locked respin sequences.

3 Oaks built the game around a train-ride theme that blends old-school fruit icons with gold-bar coins. The visual palette leans warm, amber, gold, and deep red, and the soundtrack shifts noticeably when the bonus triggers, signalling that the real action is underway. Both the base game and the bonus are accessible in demo mode before committing real money.

How To Play Coin Express Slot - Step By Step

Head to Wild.io and create a free account to start playing Coin Express.

1. Create your Wild.io account or log in, then navigate to the games library and search for Coin Express.
2. Set your bet using the stake selector. The game supports a flexible betting range suitable for most budgets.
3. Spin the 5x3 grid. Land three or more matching symbols across any of the five paylines for a base-game win. The wild symbol substitutes for all regular paying symbols.
4. Watch for bonus coin symbols to land anywhere on the reels. When enough appear, the Hold and Win bonus triggers with three respins awarded.
5. During the bonus, locked coins reset the respin counter to three each time a new coin lands. Collect as many coins as possible to stack values and aim for the Mini, Minor, Major, or Grand Jackpot.
6. A Collector symbol during the bonus gathers all visible coin values and adds them to your total in one shot.
7. When the respins end, your total coin value is paid out. If you fill all positions, the Grand Jackpot worth 5,000x your stake is awarded.

You can also deposit using various supported payment methods.

Coin Express Slot Theme & Graphics

Coin Express runs with a classic casino-gold-meets-steam-train aesthetic. The background shows a stylised locomotive in warm amber and copper tones, and the reels themselves sit inside a heavy gold frame that reinforces the jackpot theme.

Symbol art is deliberately retro: cherries, lemons, plums, grapes, watermelons, a gold bell, and a glowing BAR tile. The coin bonus symbols break from the fruit theme visually, carrying clear numerical values in bright gold against a dark background so players can track their accumulating total.

The audio design follows suit. The base game has a steady, rhythmic sound that evokes a train in motion. When the Hold and Win bonus kicks in, the music sharpens and the respin countdown appears prominently, making the tension visible. The game scales cleanly to mobile screens with no layout shift between desktop and handheld play.

Coin Express Slot Symbols & Paytables

Understanding the symbols in Coin Express is straightforward: the lower half of the pay table uses fruit icons, the upper half uses classic casino symbols, and the bonus coins sit outside the regular pay table entirely. Each symbol type serves a distinct role in how the game pays.

Special Symbols

The Wild symbol substitutes for all regular paying symbols and helps complete five-payline combinations when one symbol is missing. The Bonus Coin symbol is the key to the Hold and Win feature: it does not pay in the base game but locks in place once the bonus triggers, carrying a monetary value that contributes to the total payout. The Collector symbol is a special bonus-only symbol that sweeps all visible coin values from the board in a single action, converting the accumulated total into an instant win addition. Four Jackpot symbols, Mini, Minor, Major, and Grand, can appear as high-value coin positions during the bonus round, with the Grand Jackpot representing the full 5,000x ceiling.

Coin Express Bonus Feature & Special Features

Hold & Win Bonus

The Hold and Win bonus is the core feature of Coin Express. It activates when a sufficient number of bonus coin symbols land across the 5x3 grid. Each coin locks in place, and three respins are awarded. Every time a new coin lands during those respins, the counter resets to three again. The round continues this way until no new coins arrive, or all nine positions on the grid are filled. Coins carry individual values that stack across the board, and when the respins conclude, the total is paid out. Filling the entire grid awards the Grand Jackpot, 5,000x the bet.

Collector Symbol

The Collector is a bonus-only symbol that can appear during the Hold and Win respins. When it lands, it instantly sweeps every visible coin value from the board, sums them, and adds the total directly to the win counter. A well-timed Collector on a board with multiple high-value coins and jackpot symbols already locked in place can dramatically boost the final payout in a single trigger.

Fixed Jackpots

Four fixed jackpot positions can appear as bonus coin symbols during the Hold and Win round: Mini, Minor, Major, and Grand. The Mini and Minor jackpots award smaller multiplier values and appear more regularly. The Major jackpot sits above them, and the Grand Jackpot, the 5,000x prize, requires filling all available grid positions. Unlike progressive jackpots, these values are fixed and reset immediately after being won, so the ceiling is always clearly visible before you spin.

Wild Symbol

The Wild symbol substitutes for any regular paying symbol on the five paylines, filling gaps in potential winning combinations. It does not substitute for the Bonus Coin symbols and has no special multiplier attached, its role is purely to support base-game payouts and extend winning lines that might otherwise fall one symbol short.
