Developer Gold Express by 3 Oaks Gaming is a 5x4, 20-line slot released in November 2021. The game is built around a Gold Express train theme, with a Hold & Win bonus round, fixed jackpots and free spins. A demo version is available, allowing players to play for free and practice before playing for real money.
The BOOST FEATURE is triggered when a Gold Coin bonus symbol lands with a Piggy Bank boost symbol, paying out all visible Gold Coins. The main bonus is activated by six Gold Coin bonus symbols. These symbols become sticky, the remaining positions are cleared, and three respins begin. New symbols that land during the feature also become sticky and reset the respin counter. Bonus coins may carry MINI, MINOR or MAJOR jackpots, while filling the board can award the GRAND JACKPOT of x2,000 the bet.
During free spins, Power Wilds with multipliers can appear in winning combinations, with multipliers capable of increasing each other. The slot uses train imagery and mountain scenery, with mechanics focused on coin collection, respins and jackpot prizes.
