Dragon Bonus Opens More Track
The Hold & Win Dragon Bonus begins with three extra rows positioned above the original 5×3 grid, but those additional spaces start locked. Green Light symbols unlock the extra rows one at a time, creating more room for bonus symbols as the feature develops.
Fixed Mini, Minor and Major Jackpot symbols can land during the Dragon Bonus. The feature also includes a Collect symbol, which can gather all visible prizes.
Another safeguard comes from the Saver Coin. It has a chance to activate when the respin counter reaches zero and recharge the counter, allowing the bonus to continue.
Fill All 30 Cells for a Double Payout
Once all three additional rows have opened, the fully expanded bonus area contains 30 cells. Filling every one of those positions doubles the feature's total payout.
Unlocking every row also creates the route to the game's biggest secondary feature. If another Green Light symbol lands after the rows are fully unlocked, it opens the Golden Gate and prepares the Dragon Express to arrive when the bonus round ends.
Dragon Express Brings the Treasure
The Dragon Express can send as many as two locomotives across the screen, each pulling wagons loaded with instant rewards. These can include cash prizes and Mini, Minor or Major Jackpots.
The Grand Jackpot is reserved exclusively for Dragon Express, making the train feature the only route to the game's highest jackpot tier.
Free Spins and Two Bonus Buys
Free Spins provide another feature route alongside the Hold & Win mechanics.
Players can also purchase direct access to either the standard Dragon Bonus or the upgraded Deluxe Dragon Bonus.
Full Steam Toward the Golden Gate
Rail Dragon turns its bonus into a journey that keeps opening new sections of track. Green Lights expand the grid, Collect and Saver mechanics can keep the feature moving, and opening the Golden Gate clears the way for treasure-packed locomotives to arrive. With steam rising and the dragon-headed train racing through the mountains, the biggest destination is the Grand Jackpot hidden inside Dragon Express.
