Gold Factory Slot


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!

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!

When this game was released some time ago, I can't recall when, I was impressed with its graphics and overall presentation. It looks very interesting, very vibrant with lots of colours, and very tempting too. When I got some free spins offer to play it, I didn't waste any time. I didn't win anything with those free spins, but I got a good impression on it. Microgaming games seldom attract me a lot, but there have been exceptions of course, like Immortal Romance, Playboy and Games of Thrones, but Microgaming games always tend to end up with a love-hate relationship with me, because I find it so hard to win from them. Probably just a personal jinx, who knows, but that doesn't stop me from playing them once in awhile.

The logo 'Gold Factory' is the Wild symbol, paying 150x the total bet for 5 of them, which is lower than the usual value. The Bonus Gold Coin is the Scatter symbol, paying 200x the total bet for 5 of them, which is quite good, and getting 3 or more of these symbols trigger the Gold Factory Bonus game, starting with the Boiler Room Bonus game, followed by the Free Spins Bonus game or the Reactor Bonus game. The monocled Man pays 50x the total bet, the Boy 30x, the Factory 20x, and all others from 16x down to 1.6x the total bet for 5 of each kind. The values are not that high, but aren't that low either, so I would say it's about an average paytable.

The best part of playing Gold Factory is in the Bonus games, no doubt about that. The base game doesn't provide much opportunities for good wins, so the best wins can only come from any of the Bonus games. In the Boiler Room Bonus, you get to pick 4 out of 12 canisters to win a Free Spins game, a Reactor Bonus game or cash prizes. Getting both the Free Spins and the Reactor Bonus symbols activate the 2nd level Boiler Room Bonus game. I couldn't get this feature yet so far. The Free Spins Bonus games - once this is activated, a second screen pops up, click the spin button, the meter rolls, and the two numbers on the reels are the number of free spins won. This can be from 10 up to 35 free spins, but without any win multiplier. More free spins cannot be retriggered. Damn! That doesn't look good at all. The Reactor Bonus game - Pick out one canister at a time out of 12 canisters to reveal cash prizes. Getting 2 'Malfunction' symbols end the picking. All unselected canisters award 1x the total bet win.

True enough, playing Gold Factory can be very exhilarating and exciting, especially the Bonus games. The base game itself plays quite well in fact, with frequent small wins and with plenty of on-screen animations, keeping the interest going, but once you trigger the Boiler Room Bonus game by getting 3 or more Scatters, the fun really begins! I've managed to get the Free Spins game a few times, the Reactor Bonus game a few times too, but couldn't get both the symbols all at once yet, so I wouldn't know how the second level Boiler Room Bonus game would play. I presume it may be the same as the first level but with better prizes. My best win on this Gold Factory game is only 62x my bet so far, but I'm sure much higher wins are possible. I just couldn't get them yet, despite having played the game several times over the years. Maybe one day, sooner or later.
