Gold Express runs on five-by-four reels with twenty lines. A piggy-bank boost symbol alongside a cash coin collects the visible coin values. Six coins open Hold and Win, locking symbols while new arrivals reset three re-spins. A separate free-spin mode introduces Power Wild multipliers that can multiply each other in a winning combination. Its train theme accompanies both coin collection and reel wins, rather than describing a racing instant game.
