Gold Factory

Gold Factory by Microgaming, now Games Global, is a 5-reel slot with 50 paylines and an RTP of 96.54%. The game uses a steampunk mining theme, with gold, bronze and industrial machinery forming the backdrop for symbols including gold bars, coin piles, factory devices and character icons. A Gold Factory badge acts as the Wild, while the Scatter symbol is linked to bonus features.

Three or more Scatter symbols trigger the Gold Factory Bonus, which opens the Boiler Room Bonus. In this feature, players pick 4 out of 12 items to reveal cash prizes, while two hidden malfunctions can end the round without a prize for that pick. The feature set also includes the Reactor Bonus, shown with a mechanical reactor-style layout and a total win display.

A separate Free Spins feature can award 10 to 35 spins, with all wins doubled during the round. The demo version is available to play for free, allowing players to practice before playing for real money and to review the slot’s bonus structure, symbol values and paytable details.
