Coils of Cash

The game uses six main reels in a 3-4-4-4-4-3 shape, plus the four-position Power Coil reel above the middle reels. That creates 2,304 ways, with wins reading from left to right across adjacent reels. Winning symbols disappear after a hit, then new symbols drop into the empty spaces; only the highest winning combination for each symbol is paid. The low symbols are 9, 10, J, Q, K and A, while the premiums are four odd laboratory machines. Premium six-symbol wins start at 2.5x the stake before the coil multiplier touches them, so the base game alone is not the attraction. It is a charging pad for the top reel.

Power Coil is the whole reason the math gets interesting. The horizontal reel sits above reels 2 to 5, and each of its four positions can carry a multiplier. At the start of a base-game spin those values reset. Each cascade on the matching vertical reel increases that reel's multiplier by +1, up to 5x. A win only receives the boost if it uses a symbol from the Power Coil row. When more than one boosted coil symbol participates in the same win, the multipliers multiply together rather than simply adding up. Four 5x positions can therefore create a 625x modifier. Most spins never get close. The mechanic needs both cascades and the correct symbol connection, which is why the game can feel quiet before it suddenly snaps.

Three, four, five or six scatters trigger 10, 15, 20 or 25 free spins. That spread matters because the round does not merely repeat the base game with extra spins attached. Any Power Coil multipliers active on the triggering spin carry into the feature, and inside free spins they do not reset between spins. Each new cascade can keep pushing the relevant reel up toward 5x, so a bonus that starts with live multipliers is immediately more dangerous than a clean trigger. Additional scatters during the round add two more free spins each. This is where the 30,000x ceiling lives, but it is also where the volatility becomes obvious: a bonus without useful coil positions can burn through spins with little damage done.

The published stake range converts to roughly CA$0.16 to CA$161 per spin using the current mid-market conversion rate. Canadian operators may round the available stake steps inside their own lobby. There is no reliable Ante Bet or Bonus Buy route listed for the standard build, so the free spins have to be landed through regular play. That is better for pacing than instant 80x or 100x buying, but it also means impatient players may leave before the Power Coil ever gets a proper chance to work.
