To highlight just how rare the yellow metal actually is, is why so many games feature a theme around it, including Microgaming's Gold Factory slot.
What Microgaming have done is focus on two elements surrounding this precious metal. Of course the first is its magnificence, which is shown in piles of Gold bullion bars, mining trucks filled with gold and of course, piles of gold coins.
The second element is perhaps more linked in with the title of the slot and this is based on the refining process that helps create the gold, so we're looking at here heavy machinery, transportation and all the things that turn the raw, unprocessed flakes and nuggets of gold, into the gleaming pure shiny gold visible on the other slots.
The first thing that is immediately apparent with the Gold Factory slot is that it has done away with the playing card low symbols. The game is set in the factory itself, so Microgaming made the wise decision to abandon those ubiquitous low symbols and replace them with symbols more in keeping with the theme of the game.
The slot itself is a 5x3 reel game that consists of up to 50 paylines in play, although you can reduce this amount if you would prefer to do so. You can also adjust the size of the coin value you wager on each of the active paylines to increase or decrease the size of the bet. This means you could wager from as little as 0.01 per spin up to a maximum of 100 per spin and as such, this game will appeal to lower stakes players as well as higher rollers.
The base game plays at a nice pace and there is a good selection of wins both of lower value amounts and the occasional bigger win, however it is when you trigger the bonus game that the Gold Factory slot really comes alive.
The first thing to note are the animations which are particularly effective for this slot and which do transport the player inside this vast gold-producing structure. The bonus game appears when you land three or more of the Gold Coin scatter symbols across the reels. Wins of up to 619,000 coins are possible in the bonus game.
The round starts in the Boiler Room, where smelted gold is discharged into the train. You pick four from the 12 available hoppers. These usually reveal bonus cash amounts that the player wins but if you are lucky, it can also reveal additional tokens that offer you a chance to play another bonus game. If you trigger a bonus game on one of your first three picks, once the bonus has played through you will go back to the Boiler Room to complete your quartet of picks.
There are two bonus games you can trigger. The first is a free spins game and here you have to select one of two buttons. You receive between 10 to 35 free spins depending on the button you pick and you also receive a 2x multiplier on any wins in the free spins round.
The other bonus game is the Reactor Bonus and this is a pick'em game where the player operates points within the Reactor until they cause a malfunction in the game ends. For every point a player successfully operates, a cash prize is awarded. Two out of the twelve points will malfunction and you keep picking points to activate until a malfunction occurs.
Gold Factory looks and plays superbly well and has a great mix of addictive game-play, excellent bonus games, superb animation and sound and it is also very affordable for all players.
