Gold Factory Slot

Microgaming’s Gold Factory is widely renowned as one of the leading gold mining-themed slots on the net, and it is no hard to see why. Jam-packed with inventive and at times quirky graphics, Gold Factory features 50 lines of action and carries a very prosperous 619,000-coin non-progressive jackpot prize. That can only be won in the bonus round, though the game does have an RTP (return to player) rate of 96.54% which makes it worth playing all the same. Gold Factory allows total control over how your bets are constructed, so expect to be able to wager anything from 1p per line per spin up to £1,000 per spin on this game.

Special features

You won’t miss the wild symbol in this game. It appears as the Gold Factory logo and can substitute itself for all other symbols in the game, save for special icons. The main special icon in the game is the golden coin, and this bonus symbol can trigger the main special feature in the slot.

Landing the golden coin symbol on the reels a total of 3, 4 or 5 times will trigger the Boiler Room Bonus. From there, players can select 4 spots from the 12 available. Players will pocket instant win cash prizes as well as one of two bonus rounds.

Bonus features

There are two of those, both triggerable from the Boiler Room Bonus. The first of these is the free spin bonus which promises between 10 and 35 free games. The other feature in the game is the Reactor Bonus and it can see players select from various bits and pieces to win cash prizes until they discover one of the malfunction icons, which ends the feature.


Gold Factory is certainly an interesting slot to play if you like big wins and plenty of them. The bonus rounds are creative and exciting, and the fact that you get to pocket a bit of free cash before the main features (unless you are extremely unlucky) makes the game even more appealing to play.
