Welcome to the Coils of Cash slot machine review by Play N Go. The Coils of Cash slot machine is set in the 19th Century, a time where soon-to-be famous inventors were just starting to experiment with electricity, hence the name. Such a setting may, at first, seem unusual for a slot machine game but there was a certain buzz about the pioneering world of science back then and that buzz is certainly what this game tries to capture.

The backdrop really helps set the scene with some primitive-looking electrical devices and Art Deco lettering. Overall, it probably looks quite plain but perhaps that was a deliberate attempt by the developers, Play ‘n Go, to undersell the excitement to follow as soon as you start playing. There’s a definite retro-futuristic feel to this game that fans of steampunk will just love. The higher-value reel symbols, for example, are all gadgets that look like what a Victorian scientist might have imagined the future would bring.
To land a win in this game you’ll need to match anywhere between three and six winning symbols across your eligible paylines. Don’t worry, there are lots of the usual features to help you along the way including wilds, scatters and free spins of course.
One of the most intriguing and potentially profitable features is the cascading mechanic which kicks in after each win you land. Winning symbols are swiftly removed allowing new symbols to drop down into the empty spaces and potentially create further wins. As with other such features, the cascade continues until no new wins are created. As you see your wins accumulating during a cascade, you’ll wish it will never end.
The horizontal reel is known as the Power Coil and ties in with the cascades. Each symbol on the Power Coil can have a multiplier activated that can be anywhere between 1x and 5x. If you are lucky enough to secure more than one multiplier, the multipliers are multiplied together up to a maximum of 625x. The multipliers are reset when your cascade sequence inevitably ends.
Land the scatters and you’ll bag yourself plenty of free spins.
Number of Scatters Number of Free Spins
3 10
4 15
5 20
6 25
Land more scatters during these free spins and you’ll get two more free spins for each scatter you spin in. Any outstanding multipliers from the Power Coil will remain and not be reset until the feature ends allowing you to potentially rack up even bigger wins.
Coils of Cash slot machine has a somewhat unusual theme for a slot. Fans of steampunk will love it as will science lovers in general. The game is visually quite plain and yet highly engaging. The features are nothing out of the ordinary but, thanks to some of the multipliers, wins can quickly mount up. That said, it is a high volatility game and so that means you could be waiting a while for a win or you could hit a whole stream of wins. Stakes range from 0.10 to 100 so should suit most tastes and the Return to Player percentage is a generous 96.2% which should help balance out some of the high volatility when you do hit a winning streak.
