Play N’ Go takes a tour of a mad scientist’s laboratory in Coils of Cash, with the coils of the game’s title the coils of electricity that zap winning symbols out and allow them to be replaced by new symbols. If this sounds like it could be similar to a cascade feature such as the Rolling Reels™ feature in the Shamrock Holmes Megaways™ slot, or most other Megaways titles, you would be right. That’s not where the similarities to Megaways titles stop, either.

The top extra reel – the Power Coil reel – contains Wild symbols and other game symbols to help complete winning combinations. Similarities to Megaways slots aside, the Coils of Cash slot also serves up plenty of differences, not least the win multiplier added to every winning combination when the symbols on the Power Coil reel complete winning combos.

Pros & Cons

  • Massive win potential, up to x30,000 your bet!
  • Power Coil multipliers carry over to Free Spins.
  • The Power Coil offers up to x625 win potential from a single spin.
  • Wilds only appear on the Power Coil reel.
  • The Free Spins game is the only dedicated bonus feature.
  • Similarities to Megaways™ slots.

How to Play

Play ‘N Go’s trademark betting interface returns to take its position up beneath the reels. Click the left and right arrows to move up and down the betting scale, and press the green spin button when you are ready to spin the reels. Adjacent symbols match left to right to complete winning combinations, with any wins that complete on the Power Coil reels sparking an incremental win multiplier for the next spin, up to x5. It has some of the hallmarks of NetEnt’s Wild-O-Tron 3,000 slot from 2018, though the x30,000 max jackpot on Coils of Cash is far superior to that release. The Wild symbols on the Power Coil above the reels substitute for all game symbols except Scatters, three of which are required to trigger the Free Spins bonus game.


All of the game symbols are designed with circular hatches as their backdrops, which is explained when the Scatters open to reveal a blue glowing energy ball behind the hatches. These are designed in similar fashion to other online slots from Play ‘N Go, such as Diamond Vortex and Reactoonz 2. Play ‘N Go uses various pieces of electric machinery as the high paying symbols, with what looks to be a 1950s TV as the game’s top paying symbol. It awards x5 your stake for landing 6 adjacent symbols, while the lowest paying symbol, the humble 9, awards just x0.8 your stake for 6 adjacently. The Wild symbols only appear on the top Power Coil, and so don’t offer any additional payouts like you might find in other online slots.


The Coils of Cash Free Spins feature launches when you land 3-6 Scatters, which can be launched either straight from the base game or following any winning cascades.
