Personal testers’ opinion about Gold Factory slot
Besides the mentioned elements here, you can enjoy the wonderful visuals (design, graphics, and animations), the optimistic soundtrack and encouraging sounds plus narrating, and last but not least, the multi-level bonus round. So, all that seems at first glimpse standard and typical is actually pure gold for Microgaming, as this turned out to be one of their most successful online machines.
Waiting for a bonus in the Gold Factory slot machine can be super lengthy for your nerves and exhausting for your bankroll. Statistically, every 209th spin is expected some bonus round. While in actuality, you just sit tight and hope for the bonus, often much longer (280-300 spins). Only 19% of the bets are reserved for the payouts of the bonuses. The probability of getting any hit (payout combination) is close to 39%, which is a good figure, which combining with the decent paytable are certainly a recipe for many successful sessions.
However, we weren’t super lucky playing the golden reels. We managed to obtain only 103x the bet as a maximum of all spins, and our average from the bonus was just over 54x the bet. The slot scored 5.23 points (out of 10) on our wagering scale, i.e. right in the middle, hence, neutral advice for the bonus hunters.
Review and recommendations by the testing team
- Our team enjoyed the steam-punk/industrial fictional design of the slot. But like with all the slots, what matters the most is the paying potential. The slot often teases with 2 Golden Bonus Coins (not enough to trigger the bonus round), giving the impression that a big win is just around the corner. When in fact, waiting for the bonus can be super stretched. And after playing 1 bonus round follows a long interval (200+ spins) with no bonus game again.
- During our tests, we often got 4OAK and 5OAK, but only with the lowest-paid symbols. We didn’t see good combinations of high-value symbols, although, in theory, that is surely possible.
- Gold Factory slot machine is not good at keeping the balance, behaving at the extremes – delivering zero, or 5OAK. Nothing in between. Or making you go through a dead spins streak, or suddenly giving you a few lines with winning symbols. In the meantime, the bankroll is not kept well.
- The 2 Pick and Click bonuses deliver instant cash prizes. Naturally, level 3 holds higher amounts than level 1. According to Microgaming, the ultimate reward of the level 2 – Free Spins is 519 000 coins and level 3 – 619 000 coins. But as usual, players’ highest expectations are related to the Free Spins excitement. Unfortunately for our test team, we had only mediocre results in the Free Spins – 50x-55x the total bet. A little better luck with the Reactor Bonus – around 100x the bet. But all this couldn’t make up for the loss we endured during the regular spins.
- All things considered, the prospect of rendering large prizes is onboard; only you need a big bankroll to play long enough to experience all 3 levels of the Bonus game, and most of all to survive until it is triggered.
- So, be prepared for A) many dead spins, B) quickly gulping your money if you are unlucky or you play recklessly, and C) often poor Free Spins results, even after a long time waiting.

How to win at the Gold Factory slot machine? (Conclusion)
- We cannot emphasize often enough: Always practice with the slots in the free DEMO version before investing real money.
- This is one very popular Microgaming slot, but it still is wise to play at big casinos, where the prize pool is filled quicker, so the chance that the slot is in a ‘hot’ mood is real.
- We give neutral recommendations to the bonus hunters, who attempt to fulfill the wagering requirements.
- If you decide to deposit real money on the Gold Factory slot machine, it is advisable to have a minimum bet balance of 200/250 bets, enough to stick around until triggering the Boiler Room round.
- We do not recommend reducing the number of active pay lines. Spinning on less than 50 lines surely allows playing with smaller bet sizes but ultimately minimizes the chances of good payouts. Better play with steady medium size bets. For example, 20-30 coins per spin.
- The optimal bet is customarily 1/200 of your starting capital. Even if you decide to play with another ratio, don’t go all in via the highest stake.
- The best tactic with Gold Factory is stopping your game session on time. For this slot, the point of exiting seems to be a balance surge with 30-40%. Once you reach this apex, you should quit your game. Also, after a Bonus round, which delivered a large payout, you should pause your session or move to the next slot.
