Innovation is the name of the game, and the Gold Factory video slot is a great example of several forms of innovation by Microgaming. It starts with the 50-payline format with five reels and three rows, a format that you do not see all that often. The betting scheme is also very atypical with coins ranging from just $0.01 to $0.10 apiece, but you can bet up to 20 coins per payline or 1,000 coins per spin. This gives you a very precise control over the bet size per spin that you're comfortable with.
The Gold Factory logo is wild in this game, and you'll get a 7,500x jackpot for five of them as long as they land on an activated payline. Because Gold Factory game centers around a factory that makes gold, it makes sense that a number of workers would show up on the reels. The Factory Owner is a high-paying example of this, and five of him will get you a 2,500x win. You can also get 1,500x for five of the boy or 1,000x for five of the factory. These wins are weighted towards the upper end of things, and that gives the game a high volatility overall
Get three or more of the scattered gold coin symbol to be taken to the Boiler Room Bonus round. You pick up four boilers from a list, and you'll be able to pick up three different types of bonus features from this list. This includes instant pays, free spins with a 2x multiplier or the Reactor Bonus. The Reactor Bonus is essentially a bottomless pick a box style feature where you keep picking until you hit a stop symbol. Gold Factory was also one of the first tournament slots introduced by Microgaming.
