Coils of Cash Slot RTP, Details & Wager Limits

?MAX WIN: The most you can win per spin is 30,000 x your total stake.

The game mechanic used in the Coils of Cash slot is a little unusual. You’ll see 6 reels, each of which is made up of 3 rows, which spin vertically. Above that is the Power Coil reel which sits above reels 2 through 5 and spins horizontally. Combined, they offer 7 reels and 2,304 ways to win. Those winners are formed by landing matching symbols on 3 or more adjacent reels, starting from reel 1.

The stake limits here are standard for a Play ‘n GO slot. Stakes range from between 10p and £100 per spin. You’ll also find the developer’s usual autoplay and turbo spin options in Coils of Cash. Click on the orange button above the spin button or the lightning bolt respectively. If you’re using a mobile, head to the settings and you can amend everything from there.

The Coils of Cash RTP is 96.2%. This is a game that crackles with energy and that’s certainly the case when it comes to variance. The volatility is extremely high. On a scale of 1 to 10, we’d rate this the maximum 10. Unusually for a Play ‘n GO title, the maximum win is a massive 30,000 x your total stake per spin.

Theme – Audio & Design Features – enter an electric 19th century generator


The design in the Coils of Cash slot is very impressive. Inspired by the 1893 World’s Fair, the game focuses on the high point of humanity where great minds like Tesla, Edison and Westinghouse came together to change the future. There’s a vintage, almost art deco feel to the visuals here.

The reels are set within an electrical generator. There you’ll find sombre neon A to 9 royals alongside a collection of arcane electrical equipment. The top symbol looks like a very primitive television and pays 1, 2, 3 or 5 x your total stake if you land 3, 4, 5 or 6 in combination. There’s also a wild which can appear on the Power Coil positions and substitute for all the standard symbols.

The top-notch design and super explosive gameplay evident in the desktop version are also present in the Coils of Cash mobile and tablet slots. The classy visuals are super sharp, even if you’re playing on a small screen. You won’t lose anything playing Coils of Cash on a smartphone.

Coils of Cash Bonus Features

There might be a rather vintage feel to the design in Coils of Cash but the gameplay here is innovative and bang up to date. Look out for cascading reels wins, Power Coil multipliers and a free spins feature.

Cascading Reels feature

The action in Coils of Cash plays out on a cascading reels game engine. After a winner is formed, the successful symbols are zapped off the reels and new ones drop in and replace them. The cascades continue as long as a new winning combination is created.

Power Coil feature

625x: 5x multipliers on all 5 reels combine to give you a 625x multiplier (5x5x5x5x5x5 = 625).

Above reels 2 through 5, you’ll see a reel that spins horizontally. This is the Power Coil. It will remind you of the top row found in Megaways. Anyway, wilds can only land on the Power Coil.

It’s also here that you can bring multipliers into play. Each symbol cascade increases the multiplier for the Power Coil position directly above. The multipliers on each of these reels can get as high as 5x.

If you manage to activate multipliers on more than 1 reel in the same winning combination, their value is combined. If all 4 reels, reach their maximum 5x multiplier, you’ll receive an enormous 625x multiplier payout boost (5x5x5x5=625x).  The Power Coil multipliers reset to 1x at the start of each base game spin.

Free Spins feature


The energy orb is the game’s scatter symbol. Land 3 or more energy orbs on the same spin to trigger the Free Spins feature. As with most online slots, more scatters give you more free spins:

  • 3 scatters = 10 free spins
  • 4 scatters = 15 free spins
  • 5 scatters = 20 free spins
  • 6 scatters = 25 free spins

Any Power Coil multipliers from the triggering spin are carried over into the free spins. The Power Coil multipliers don’t reset during the free spins either. They remain active until the end of the round. Each scatter that lands during this round adds another 2 free spins to your total.

Coils of Cash Review Summary – electrifying payout potential

The Coils of Cash slot is an offering that’s fizzing with energy. Visually, it’s superbly done, with the retro imagery very easy on the eye.  The gameplay is a little unusual given the Power Coil reel but all the better for it.

Highly volatile, expect plenty of lean spells here. The action can really spark into life in you get on a run with the cascading reels and bring massive multipliers up to 625x into play. Most Play ‘n GO titles offering 5,000 x stake or even 10,000 x stake wins at best. Coils of Cash absolutely dwarfs those numbers with a potential 30,000 x stake max win per spin!

If you’re tired of the same old diet of fruit machines, ancient Egypt and leprechauns and fancy trying a high variance slot that offers something different, that’s exactly what’s on offer in Coils of Cash. Happy with more straightforward gameplay? Play ‘n GO’s Moon Princess will serve you well.
