Play Gold Factory for Free

This game is a tale of the Mad Inventor and his trusty Assistant who accompanies him to the bottom of the ocean in search of treasure in their underwater submersibles. There you will find symbols that represent Trains carrying Gold, a Gold Factory, Gold Bars, Gold Coins, Underwater Submersibles, and Carts full of Gold.

The Gold Factory Logo is wild and it substitutes all other symbols on the reels apart from the Gold Coin Bonus symbol.

You can win up to 61,900 coins in the Gold Factory Bonus round. Trigger this feature by landing 3 or more scattered Bonus Gold coins on the reels. You need to also keep in mind that 2 or more Bonus Gold Coins will also reward you with scatter pays, which can go as high as 10,000 coins for 5 of them when playing at maximum bet.

In this bonus round you will be required to pick 4 out of the 12 items so as to reveal prizes. More so, you can trigger 2 more bonus rounds while in this level. To do this, simply find the Free Spins or the Reactor Bonus symbols. If you happen to trigger either of these bonus events, then the game will commence immediately on trigger, and you will be directed back to the Boiler Room once your second level bonus ends. You can trigger both bonuses while at the Boiler Room.

As mentioned, the Free Spins Bonus can be triggered while in the Boiler Room. When this happens, you will be asked to click the Spin button that will reveal between 10 and 35 free spins, during which all wins will be multiplied 2X. You cannot retrigger more free spins.

The Reactor Bonus is the second bonus round that you can trigger while in the Boiler Room. When this happens you will be provided with 12 items and you can start picking your items to reveal prizes. The round will come to an end when you run into the Malfunction symbol. There are 2 Malfunction symbols hidden within the 12 items. You will, however, be awarded a consolation prize for the unselected items.

This game accommodates both high-rollers and penny bettors with the bets running from 0.10 to 100.00 coins. All regular wins are multiplied by the coins bet per line.

This is a medium-variance slot, and the bonus rounds do not hit as often, but they are really rewarding when they eventually hit. If you love the idea of winning some really cool cash, you might also want to check out Mega Moolah, also by Microgaming.
