Gold Factory Slot Microgaming

Ditch the mining gear and get rich the high-tech way in Microgaming’s Gold Factory! This online video slot comes with a complex bonus feature and up to 50 lines of fun. Play Gold Factory for free on this page, or go to any of the Microgaming casinos listed below to play for real money.

When you first load Gold Factory, use the available controls to decide how much you want to bet. Start with the - and + buttons under the coin, which will change your base denomination. The “Lines” sections lets you adjust the number of active paylines. If you want to bet multiple coins per line, use the “Coins” area. Push “Spin” to begin, use “Bet Max” to spin with the highest possible wager, or push “Auto Play” to spin continuously.

As the reels tumble, symbols like gold coins, trains, and conductors will tumble down the reels and hopefully align along the active paylines. Three or more matching symbols from left-to-right will pay out an amount shown in the paytable. The Gold Factory logo is wild and will substitute for any non-scatter.

To see the inner depths of this strange factory, trigger the Boiler Room Bonus by getting 3 or more scattered Bonus Coins anywhere on the reels. You will be promptly whisked away to an array of hot boilers. Choose 4 of them to reveal instant prizes. If you’re lucky, you may unlock the Free Spins Bonus or the Reactor Bonus.

If you get the Free Spins Bonus, you will get to choose from two pods to reveal the number of free spins you win – up to 35! All wins during the free spins are doubled.

If you make it to the Reactor Bonus, you’ll be prompted to choose sections of the high-energy reactor to win big instant cash prizes. Keep picking until you hit one of two Malfunction symbols. The longer you can go without causing a meltdown, the more cash you can win!

A varied slot on all pages and 50 lines with many features is great fun. If there are up to 35 free spins and twice multiplier. Microgaming is a great master and knows what symbols to create and combine to make his games attractive. Gold factory is a valuable asset and has its charm.

I love the boiler round I think it's called, and then there's, what , a second boiler round for a bonus where your odds are good you're walking away with a great win at that point.


I disliked, oddly enough, the bonus rounds, this one works because even if you dont pick the spins, you still have to pick some dollar amounts. But to me, these types of bonuses, where you finally hit them in the base game, then you have to be lucky again and pick the free spins, it's a major drag when you have to walk away cuz you missed picking the free spins.

I never actually thought why I loved this game. It has nothing special... Okay wait I was the god of picking full reactors after hitting the bonus on a very big stakes and that's how I won a lot fo money on very shitty microgaming casinos even... with free spins feature best score: 0.30 stake because I think 0.50= 50 lines it's total trash. I felt that bonus and everything actually on full 50 is just sad. Back to the win 0.30 so 30 lines and lowest stake 400 + sth on spins, nice? if just the stake wasn't the worst :P


An advice as stated earlier do not play 50 lines. I do not know maybe it's me but really not worth only 15, 20 but mostly 30!
