Coils of Cash (Play'n Go) Slot Review

Coils of Cash: Slot Overview

Coils of Cash is a video slot developed by Play’n GO and released on January 7, 2021. The game adopts a retro technology theme centered around electricity, featuring symbols like transistors, resistors, conduits, and wiring within a forgotten factory setting. It employs a cascading grid mechanic with a distinctive Power Coil multiplier system above select reels, delivering dynamic gameplay on an asymmetrical 6-reel setup with 2,304 ways to win. High-volatility action suits experienced players seeking substantial payout potential up to 30,000x the stake, combined with persistent multipliers in the free spins round for escalating wins.

Design and Graphics

The visual aesthetic of Coils of Cash evokes a retro industrial factory, with a backdrop depicting a dimly lit hall dominated by large central machinery. The 6-reel grid features rows arranged as 3-4-4-4-4-3, framed by conduits and wiring that pulse with energy. Symbols include low-paying card values (9, 10, J, Q, K, A) in metallic finishes and high-paying retro components like circuit boards and coils, rendered in a washed-out, aged palette of grays, blues, and oranges. The Wild appears as a glowing blue ‘W’, while Scatters manifest as vibrant blue energy orbs.

Animations activate dynamically during wins: matching symbols explode in sparks and flashes, cascades drop new icons with buzzing effects, and Power Coil multipliers charge with electric surges. A fast-paced electronic soundtrack underscores the action, shifting from subtle hums in idle states to intense, club-like beats and zaps on hits. The interface is polished and mobile-optimized, ensuring smooth performance across desktops, smartphones, and tablets, with intuitive controls for bet selection and autoplay.

Gameplay Mechanics

Coils of Cash operates on 6 reels with an asymmetrical layout of 3 rows on reel 1, 4 rows on reels 2-5, and 3 rows on reel 6, providing 2,304 ways to win. Wins form by landing 3 to 6 matching symbols on adjacent reels starting from the leftmost reel. The core mechanic is cascading reels: winning combinations explode and are removed, allowing remaining symbols to drop and new ones to fill from above, potentially chaining multiple payouts per spin until no further wins occur.

Above reels 2, 3, 4, and 5 sits the Power Coil, four dedicated multiplier positions starting at x1 each spin. A win involving a reel increments its multiplier by 1, up to a cap of x5. If a winning combination spans Power Coil symbols, the payout is boosted by the product of all participating multipliers (e.g., x2, x3, x3 yields x18). Regular symbols pay as follows:

The Wild substitutes for all regular symbols to complete wins, while Scatters trigger the bonus regardless of position.

Bonus Features

The slot’s features revolve around three key elements: cascading reels, the Power Coil, and Free Spins. Cascades enable chained wins by clearing paying symbols and refilling the grid, with each sequence building Power Coil values in the base game.

The Power Coil introduces strategic depth: multipliers on positions above reels 2-5 start at x1, increment per win on that reel (max x5), and multiply together for involved wins, capping potential at x625 (x5 x x5 x x5 x x5). They reset each base spin but persist and accumulate in free spins.

Landing 3, 4, 5, or 6 Scatters in one base spin awards 10, 15, 20, or 25 Free Spins, respectively. Additional Scatters grant +2 spins each. In this round, Power Coil multipliers do not reset between spins, allowing sustained growth toward maximum values for amplified payouts across cascades.

Betting Options and Payouts

Betting ranges from €0.10 to €100 per spin, accommodating casual and high-roller play. The default RTP stands at 96.2%, with operator-selectable variants at 94.2%, 91.2%, 87.2%, and 84.2%—always confirm the active rate. High volatility means infrequent but high-value wins, with maximum payout capped at 30,000x the bet. Payouts scale with bet size via ways-to-win, enhanced by cascades and multipliers; full-reel high symbols yield 2.5x-4x base, amplified up to x625 via Power Coil.

Conclusion

Coils of Cash excels in its innovative Power Coil system and persistent multipliers during Free Spins, fostering escalating win potential up to 30,000x amid high-volatility cascades. The retro theme pairs effectively with energetic audio-visual feedback, while broad bet limits and mobile compatibility enhance accessibility. Drawbacks include the unconventional aesthetic, which may not appeal universally, and operator-variable RTP requiring verification.
