Microgaming’s Gold Factory slot is a 5-reel video pokie with 50 paylines. All wins pay out left to right (except for scatter wins which pay anywhere on the reels), and are multiples of the line bet (scatter wins are multiples of the total bet). There is a good variety of coin sizes – 0.01, 0.02, 0.05, 0.10, 0.20, 0.25, 0.50, $1.00 – and between 1 – 20 coins can be played per line. This means that the maximum bet ranges in size from $10 – $1000, with a minimum spin of 0.01.
The Gold Factory casino game is a medium- to high-volatility pokie with a maximum jackpot win of 619,000 coins (up to $619,000 when betting the maximum coin size and number on all 50 paylines), during the Gold Factory Bonus Feature.
During the free spin bonus round, there is a jackpot of 519,000 coins on offer (worth up to $519,000 when betting the max), while during base play there is a top jackpot payout of $200,000 for hitting 5x scatter symbols when betting the maximum.
The Gold Factory Bonus Feature is where the game’s biggest prizes are won. This feature is activated by hitting 3x, 4x or 5x scatter symbols anywhere on the reels and consists of two separate stages – the Boiler Room Bonus and the Reactor Bonus.
In the Boiler Room Bonus, players are presented with a new screen that features a room where there are twelve boilers. Behind 9 of these is a cash prize, 1 will trigger the additional Reactor Bonus Feature, 1 will trigger the free spin bonus round, and the last conceals a malfunction symbol, which ends the game. Up to four of the boilers can be selected, and players either collect the prize revealed, go to another bonus feature, or go back to the main game.
If players proceed to the Reactor Bonus Feature, they get a new screen where there are twelve reactor chambers – two of these conceal a malfunction symbol, while the remaining symbols conceal cash prizes. Players continue to select symbols until they hit a malfunction symbol, when they return to the Boiler Room Bonus (if there are picks remaining).
During the Boiler Room Bonus, if players reveal a Gold Factory Free Spins symbol, they go to another separate screen where between 10x – 35x free spins can be won. All wins are multiplied 2x during the free spin bonus round. Once the free spins have been completed, players return to the Boiler Room bonus if there are further picks remaining.
Other special features in Gold Factory slots include scatter and wild symbols, and auto-play mode.
The game takes place in a zany gold factory, and the symbols, design and characters have a hint of steampunk about them. The overall colour scheme is dominated by gold, while the bright and cartoon-like symbols feature gold bars, gold coins, as well as some funky transportation devices, like steam trains, submarines and flying balloons. The music is lively and jaunty, and encapsulates both the comic and industrial elements of the theme. There are fun bursts of music and animation on winning spins, and the bonus games, which are played on separate screens, also encapsulate the theme very well.
The bonus rounds are the real highlight in the Gold Factory slot and offer the biggest payouts. In addition, the gameplay is lively, the graphics are engaging and the theme adds to the overall enjoyment of the game. With scatter and wild symbols, 50 paylines and special bonus features, this is an action-packed and highly engaging pokie that also give players the opportunities for some potentially huge jackpot wins.
