Coils of Cash: Slot Overview

One upside of Play’n GO’s constant stream of releases is that, mixed in with the more forgettable titles, there are plenty of well-crafted standouts. A prime example is the straightforward but surprisingly bold Coils of Cash. At first glance it doesn’t look like anything too wild, yet a quick scan of the paytable can leave you doing a double take. For some reason, Play’n GO went all-in with Coils of Cash, delivering a seriously fun slot that can pay out in a way few others in their huge back catalogue can match.

Coils of Cash transports players to the late 1800s, when innovators such as Tesla, Edison, and Westinghouse were stretching the limits of what science could achieve. Even if some of their most ambitious ideas never fully materialised, the world gained enormously from their ingenuity. Today, when it’s dark, we flip a switch and instantly have light. It’s so simple we barely notice the massive leap in everyday life that electricity enabled. That said, it’s this era of breakthrough experimentation that forms the setting for Coils of Cash.

At first look, Coils of Cash can feel a bit like Megaways, largely thanks to the single horizontal reel positioned above the 6 main reels. However, the main reels have only 3 positions and the win ways are capped at ‘just’ 2,304, which quickly changes the comparison. Staying true to the theme, the backdrop suggests early electrical machinery, finished off with Art Deco-style lettering. It’s an attractive but fairly understated presentation, giving little hint of what’s coming.

Players can jump into the electrical boom on any device, with stakes ranging from 10 p/c to $/€100. The headline figure here is the potential, though the other stats hold up well too. A default RTP of 96.2% is solid, but it can be configured lower, so it’s worth checking which version you’re about to play. Volatility is high, rated 10 out of 10 on Play’n GO’s scale, meaning it’s about as dangerous as it gets and perfectly suited to determined players chasing Coils of Cash’s biggest hits.

Wins can be formed with three to six matching symbols. The first six paying symbols are 9-A card ranks, while the remaining four are retro-futuristic devices that are hard to neatly describe. What matters is that a six-of-a-kind with the picture symbols pays 2.5 to 5 times your stake. Assisting with combinations is a ‘W’ wild, which appears only on the horizontal reel and substitutes for any standard paying symbol.

Coils of Cash: Slot Features

The main mechanic driving the action is the cascading mechanic, which triggers after every win. Winning symbols disappear, and new symbols drop into the gaps, potentially creating additional combinations. This continues until no further wins are produced.

Working alongside the cascades is the four position horizontal reel called the Power Coil. Each symbol on the Power Coil can have a multiplier activated, increasing by +1 for every cascade on the matching reel – up to a maximum of x5. Any win that includes a Power Coil symbol with a multiplier has that multiplier applied. If multiple multipliers are involved, they multiply together up to x625. In the base game, once a cascade chain finishes, the multipliers reset.

Hitting 3, 4, 5, or 6 scatters awards 10, 15, 20, or 25 free spins respectively. Any Power Coil multipliers from the triggering spin carry into the bonus round, where they do not reset until the feature ends. Any scatter that lands during the feature adds two extra free spins.

Coils of Cash: Slot Verdict

Coils of Cash feels like something you notice in an antique store: interesting on the surface, but the more you look, the more impressive it becomes. The first real shock is discovering it’s among Play’n GO’s highest paying slots so far. It wouldn’t have been unheard of to see huge multipliers paired with limited overall potential—something that happens more often than you’d expect. Play’n GO sidesteps that mismatch by backing the 625x multiplier with maximum winnings of up to 30,000 times the stake. We’re used to 5k caps and the occasional 10k from the studio, but Coils of Cash pushes far beyond that.

Why they chose to do it in a slot that can initially seem a bit understated is hard to say. Still, for players hunting for enormous wins, Coils of Cash offers an entertaining route to chase them. Multipliers that multiply each other are usually a winning formula, and that’s exactly how Coils of Cash operates. Of course, the truly massive payouts are rare (less than 1 in 100m), but stacking several Power Coils multipliers can rapidly turn a normal win into something huge. In theory, pairing that with such high volatility is thrilling; in practice, you may want to keep your distance when it starts crackling. The cascading wins mechanic is another strong touch, reinforcing the Megaways-like vibe while keeping spins lively as you pursue those tempting multipliers.

Much like a 19th-century electrical invention, Coils of Cash is best approached carefully. It has a lot to offer, but it can also punish the careless because landing the big results won’t come easily. If it does click, though, and the Power Coils light up, you’ll feel as triumphant as Edison when he finally got his 10,000th lightbulb working the way it should.
