Base Game Info
Captain Coil by Bullshark Games is a high-volatility cluster pays slot featuring a surreal lab-themed world ruled by a mysterious serpent scientist. Played on a 6×6 grid with cascading wins, the slot rewards clusters of 5+ matching symbols and builds momentum through frequent symbol drops and wild transformations. With an RTP of 96.29%, a 29.96% hit frequency, and a powerful 15,000x max win, this release blends immersive mechanics with modern gameplay designed for fans of multiplier-driven slots and expanding cluster systems. Bets range from 0.10 to 50, making the game accessible to both casual players and high-rollers.
The base game revolves around forming winning clusters that trigger cascades, allowing new symbols to drop into place for additional win opportunities. As Snake Pod symbols slither across the reels, they leave behind Wilds and help build the Global Multiplier, turning even modest clusters into high-value chain reactions that feed into the game’s bonus features.
Slot Features
Cluster Pays & Cascading Wins
Captain Coil uses a cluster pays mechanic instead of paylines:
Win with 5+ connecting symbols horizontally or vertically
Winning symbols are removed from the grid
New symbols cascade into empty positions
Multiple cascades can occur in a single spin
Low-pay symbols include card suits, while high-pay icons such as syringes, collars, crates, and food bowls deliver larger rewards. A full 27+ symbol cluster can award up to 50x, while a full Wild cluster pays 100x before multipliers apply.
Global Multiplier
The Global Multiplier applies to every winning cluster:
Starts at x1 each spin in the base game
Resets between spins in the base game
Increases when the snake crosses Wilds or itself
Possible multiplier values range from x2 to x100
During bonus rounds, the Global Multiplier becomes progressive and persistent, allowing exponential win growth.
Snake Pod Wild Trail
When a Snake Pod symbol lands:
A snake slithers across the grid
Leaves 2 to 25 Wild symbols behind
Wilds behave like normal cascaded symbols
Crossing a Wild or itself adds a multiplier to the Global Multiplier
Additional Snake Pods may appear during cascades, amplifying cluster potential.
