Gold Factory slot by Microgaming

Gold Factory bonus features

When you venture into this glittering slot, you’ll see all the workings of a gold factory, from the trains and tunnels to the gold bars themselves. It’s the gold coin bonus symbols to look out for though, as these will trigger the lucrative bonus round.


Landing three, four, or five gold coin bonus symbols anywhere on the reels will trigger the Boiler Room Bonus. Here, you’ll click four items from a possible 12 to choose from, each hiding a different prize or bonus feature. There are two features to find:

  • Free spins
  • Reactor Bonus: keep picking symbols for prizes until the round ends by revealing two malfunction symbols

Free spins

This is one of the two features that can be played in the Boiler Room Bonus, and you can win up to 35 extra spins to play, each with a 2x multiplier. Once your free spins have ended, you’ll return to the Boiler Room.


The Gold Factory symbol serves as a wild and can substitute for any symbol except the gold coin bonus symbol.

Gold Factory jackpot

This isn’t one of Microgaming’s jackpot slots, however, you can win up to a massive 619,000 coins.

RTP and volatility

If you love a medium setting on your volatility, Gold Factory is a good choice. It offers a balance of high and frequent wins, with still plenty of chances to reel in the big prizes. The return to player is average, at 96.54%.

Gold Factory on mobile

This may be an older slot, but Microgaming has adapted it to work perfectly on mobile devices.

What does John have to say?


It’s hard to beat the classics, and Gold Factory with its plentiful features and prizes is up there with the best.
