How the Coin Train and Golden Coins Work

Base Game Collects: Golden Coin symbols land with instant cash prizes worth 1x to 10x your play.
Coin Train Positioning: A Coin Train can land only on the center reel and collects the value of every Golden Coin on the reels in the same spin.
Reel Restrictions: Golden Coins do not land on the middle reel.
Visual Coin Pile: When a Golden Coin lands, a coin is tossed into the pile above the reels purely for show; it does not affect the chance to trigger features.
Guaranteed Trigger Condition: When a spin contains at least one Golden Coin and a Coin Train together, the Hold & Win can trigger.
Bonus Seeding: If a Golden Coin triggers the Hold & Win, the feature can start with up to 6 Golden Coins and up to 3 Coin Trains already on the grid.

Hold & Win Bonus

3 Respins to Start: The Hold & Win bonus begins with 3 respins.
Resetting Respins: Each time a Golden Coin or Coin Train lands, the counter resets to 3.
Locked Trains: Any Coin Train that lands locks in place until the feature ends.
Symbols in Feature: Only Golden Coins, Coin Trains, and blanks appear.
End-of-Feature Payout: Every locked Coin Train collects every Golden Coin value once, and all collected prizes are awarded at the end.

Jackpot Trains and Jackpot Hold & Win

Jackpot Coins: Up to 6 Jackpot Coin symbols can land during a spin.
Prize Tiers: Mini (15x), Minor (30x), Major (100x), Grand (500x) your play.
Train Positioning: A Jackpot Train can land only on the center reel and collects the value of all Jackpot Coins on that spin. Jackpot Coins do not land on the middle reel.
Guaranteed Trigger Condition: When a spin contains at least one Jackpot Coin and a Jackpot Train together, the Jackpot Hold & Win can trigger.
Bonus Seeding: If a Jackpot Coin triggers the feature, it can begin with up to 6 Jackpot Coins and up to 3 Jackpot Trains already locked in.
Jackpot Hold & Win Flow: Starts with 3 respins; landing a Jackpot Coin or Jackpot Train resets the counter to 3. All Jackpot Trains lock and, when the feature ends, each locked Train collects each Jackpot prize once.
