Gold Factory Online Slot Game
Enter a mystical Gold Factory, where gold pours from a chute as a miniature train travels through the background and hot-air balloons drift across a scenic landscape. With polished animation, a multilevel bonus feature and fixed prizes, Gold Factory has a distinctive slot presentation.
Theme and Storyline
Gold Factory introduces a world of eccentric inventors and abundant gold. A precious-metal alchemist and his sidekick head out on submarine expeditions in search of treasure, aiming for the biggest mountain of gold imaginable. The game includes bonus rounds and the potential to win a jackpot of 61,900 coins. In its steampunk setting, almost anything seems possible.
Graphics, sound and animation
Microgaming gives Gold Factory a bright, gold-focused look, filled with quirky characters and themed symbols. Lively animation, a cheerful palette and an upbeat soundtrack create an energetic feel, while factory sounds and other effects reinforce the impression of a machine producing gold.
The slot blends two complementary ideas: the inner workings of a gleaming gold factory and the industrial business of mining gold bars. This combination gives the game a polished appearance and entertaining atmosphere, with payouts also highlighted in the review.
Top Casinos to Play Gold Factory:
Gameplay
Gold Factory has 5 reels and 50 pay lines, with bonus features and special symbols adding variety to each spin. Its stated payout potential is 150 000 coins.
Gold Factory centres on a gold-filled factory and steam-powered inventions. Its logo is the Wild and highest-paying symbol, substituting for every other symbol except the gold-coin Scatter.
The themed symbols include a hot-air balloon, submarine and train. Five train symbols on a line can pay up to 800 coins. Gold items such as bars pay 90 coins for five in a row, while five gold barrels pay 100 coins.
The Gold Factory logo serves as the Wild. Three in a line pay 75 coins, while five in a line pay 7500 coins.
Bonuses and free spins
Gold Factory Bonus: Landing three, four or five Scatter symbols, shown as gold coins, anywhere on the reels activates the Bonus Games.
In the Boiler Room Bonus, choose 4 of 12 containers. Your four selections reveal cash prizes or Free Spins with a 2x multiplier.
Choosing the Free Spins container opens level one, awarding between 10 and 35 Free Spins. They can’t be re-triggered, but every win is doubled. After the Free Spins round, you return to the Boiler Room and continue selecting containers until the Reactor Bonus appears and starts Level Two. Further selections in the Reactor Bonus can award smaller cash prizes of up to 7.00.
Gold Factory has a non-progressive jackpot, with a top payout of 619,000 coins.
Bet sizes, RTP and variance
Before spinning, use the minus and plus controls to choose the stake for each round and adjust the coin size. Select the number of active pay lines with Lines, and use Coins to place multiple coins on each line. Bet Max chooses the highest available wager, while Auto Spin can run the reels automatically up to 100 times. The minimum bet per spin is 0.10 and the maximum is 100.00.
The stated RTP is 96.54%, presented as a 3.46% house edge. Volatility is Medium and is described as suitable for players willing to pursue larger wins without committing too much of their budget. Smaller wins are expected more often, while larger payouts occur less frequently.
Conclusion
Gold Factory’s main appeal lies in its entertaining presentation, broad betting range and layered bonus structure. Its two-level feature includes Free Spins and the Reactor Bonus, which can award prizes and potentially strong wins, but doesn’t guarantee results.
