Slot Features
Expanding Reels – Upgrade from 3 Rows to 5
Landing three red money coins, gold bar tokens, or mystery symbols on reel three triggers the expanding reels feature. When activated, the grid expands from 5x3 to 5x5, unlocking up to 70 paylines and increasing win potential dramatically.
This expanding reels mechanic enhances both standard symbol combinations and feature trigger opportunities, making it a key part of the slot’s volatility structure.
Respin Feature – Hold and Collect Mechanics
The respin feature starts when five or more wilds, red money coins, gold bar tokens, or mystery symbols land. The number of respins equals the number of triggering symbols.
During respins:
Coins and mystery symbols are held in place
Each new coin adds one respin
Bonus symbols lock reels and contribute to the jackpot meter
Mystery symbols can reveal values up to 10,000x your bet
At the end of the feature, all symbol values are collected and paid, making this the primary path toward high-multiplier wins.
Respin Wild Feature
Three or four gold bar token wilds may randomly appear with additional wilds. These added wilds can help trigger the respin feature and improve symbol coverage. This mechanic only activates in the base 5x3 layout, keeping the feature unpredictable.
Instant Respin Feature
Even if a base spin does not naturally trigger respins, there is a chance of activating an instant respin round with five to eight red money coin symbols. This keeps gameplay exciting and reduces long dry streaks.
Blackout Feature
If every position is filled during the respin feature, the Blackout Feature activates. Players receive a free additional respin round with newly assigned coin values and a reset bonus prize meter. This increases the potential for consecutive high-value collections.
Bonus Prize Feature – Jackpot Pick Game
The jackpot bonus can trigger in three ways:
Landing an instant bonus prize symbol in the base game
Landing three Lucky Train scatters on reels two, three, and four
Collecting three bonus prize symbols during respins
When triggered, players enter a 12-item pick bonus, revealing jackpot signs until three matching symbols are found.
Possible jackpots include four tiers, awarded once per respin cycle. This feature adds an additional layer of jackpot excitement beyond the respin mechanics.
Conclusion
Lucky Train is a feature-packed Wild West online slot that combines expanding reels, hold-and-win respins, mystery multipliers, and jackpot pick bonuses into one cohesive experience. While base game wins are relatively small, the real potential lies in the respin feature, blackout round, and jackpot bonus system.
With a top payout of 10,400x your bet, scalable paylines up to 70, and multiple bonus triggers, Lucky Train appeals to players looking for a medium volatility slot with layered bonus mechanics and strong multiplier potential.
If you enjoy coin respin slots with expanding reel upgrades and jackpot features, this train is worth boarding.
