Gold Factory

Gold Factory review

The symbols match the theme: a submarine, an airship, a train, a mine cart, gold bars and coins, the factory itself, the inventor and the kid. The Gold Factory logo is the wild and substitutes for everything except the bonus symbol. Five wilds on a line pay 150x your line bet. The bonus coin symbol is actually the top-paying symbol, at 200x for five.

Bets work with coins: you choose a coin value and the number of coins per line, so the total stake depends on your settings and on the limits your casino has set.

The Boiler Room bonus

Three or more bonus coins anywhere on the reels start the main bonus. In the Boiler Room you pick 4 of 12 gold dispensers. Every pick pays a cash prize, and some also reveal a token that sends you on to one of two secondary features.

Free Spins and the Reactor

Free Spins Bonus: a spin decides how many free spins you get, between 10 and 35. Every win during the free spins is doubled. The free spins cannot be retriggered.

Reactor Bonus: a second picking game with 12 containers. You keep picking and collecting cash prizes until you hit one of two “malfunction” tokens, which ends the round.

The layered structure is what makes Gold Factory interesting. One trigger can lead to a cash pick, free spins or a second pick round, so bonuses feel varied even though the base game is simple.

Volatility and max win

Sources rate Gold Factory as low to medium volatility. Wins come regularly and the bonus is not hard to reach, but very big wins are rare. The top payout is listed as 619,000 coins. Other sites list different multiplier figures, so treat any “x stake” claim you see elsewhere with caution. There is no jackpot.

How to play

• Choose your coin value and coins per line. Your casino sets the minimum and maximum total stake.
• Line wins pay left to right. The Gold Factory wild substitutes for every symbol except the bonus coin.
• Land 3 or more bonus coins anywhere to enter the Boiler Room and pick 4 of 12 dispensers.
• Tokens in the Boiler Room unlock either the Free Spins Bonus (10–35 spins, all wins doubled) or the Reactor picking bonus.

Gold Factory RTP

Gold Factory’s published RTP is 96.54%. That is a solid figure for a 2011 slot. As always, check the game’s info screen at your casino, because operators can run different versions.

Our verdict

Gold Factory has aged better than most slots from 2011. The base game is plain, but the Boiler Room and the two follow-up bonuses add real variety. It suits players who prefer frequent features to chasing huge multipliers. For another classic from the same studio, try Thunderstruck or Avalon.
