Play Coils of Cash

Coils of Cash by Play’n GO gives its electrical inventions a working role on the reels. Winning symbols disappear, and the Power Coil above them increases its multipliers as replacements drop in. Wilds do the usual job of completing combinations in slot games, with one restriction here: they appear only on that top reel. During Free Spins, the multipliers stay between spins. 

The 1893 World’s Fair inspires a version of the future full of brass machinery and exposed wiring. The gadgets have small curved screens, heavy cases and oversized controls, as though their inventors have squeezed new technology into Victorian equipment. One displays a glowing blue stack of coins above a thick copper coil. Another has a green monitor tucked beside a large circular fitting. The card symbols follow the electrical theme too, with letters and numbers lit inside coloured glass bulbs. Even the Wild looks bolted together, its large W surrounded by a gold ring, screws and short lengths of coil. 

Wilds substitute for regular symbols, while Scatters trigger Free Spins. 

Cascading Wins 

Winning symbols disappear, leaving the others on screen as replacements fall into the gaps. A new combination pays and starts another cascade, with the sequence continuing until no further win forms. 

Power Coil 

Each Power Coil position above reels two to five gains one multiplier level when symbols cascade beneath it, up to 5x. A win must include the top symbol to receive that position’s multiplier, and several can multiply together to reach 625x. These values reset before the next base-game spin. 

Wilds 

The W appears only on the horizontal Power Coil and replaces any regular paying symbol. When it helps complete a win, the multiplier at that position applies too, but Wilds cannot stand in for Scatters. 

Free Spins 

Three, four, five or six Scatters award 10, 15, 20 or 25 Free Spins respectively. The bonus keeps the Power Coil values built during the triggering spin, and further cascades can raise them to 5x each. A spin without a win leaves those multipliers intact. 

Additional Free Spins 

Every Scatter during the bonus adds two Free Spins, so one is enough to extend the round. The extra spins keep the same Power Coil values, which reset only after the entire bonus ends.

The Power Coil adds a fourth symbol above reels two to five, while the outer columns remain three symbols tall. This gives 2,304 ways to win, an alternative to the fixed paylines found in an online casino. A blue coin display on each of the first three reels pays even if one sits at the top and another at the bottom. Two copies on the second reel would make two winning combinations through those columns. Longer matches pay the higher table value, and winning symbols disappear to leave room for replacements. 

• Gonzo’s Quest increases its Avalanche multiplier after consecutive wins, with replacement symbols continuing the same spin. 
• Reactoonz shares the science-fiction theme and cascading symbols, with winning clusters charging meters that activate Wilds and other modifiers. 
• Rich Wilde and the Tome of Madness counts symbols removed during cascades, using collection milestones to trigger changes on the grid. 

We see Coils of Cash as a game for following the reels closely. Four separate multipliers demand more attention than one shared value, especially when several combinations pay at once. Free Spins give those numbers time to build, and keeping them after a blank spin makes the bonus meaningfully different from the base game. Play’n GO also gives the electrical theme a purpose, with the Power Coil doing the work its name suggests. The main drawback is how much there is to track, since a high value above a reel helps only when its symbol joins the win.
