Slot Summary

In 2021, Skulls Heap paired a Day of the Dead Festival setting with a broad 6-reel, 4096-way format. GONG Gaming uses ordinary adjacent-reel combinations for the base game, then shifts emphasis to Free Spins and Wild Symbol multipliers. Its 96.04% RTP, High volatility, and 3000x maximum win describe a game that reserves its sharpest changes for the triggered round rather than the initial spin.

How It Plays

The 6-reel, 4-row grid evaluates matches across 4096 ways. Symbols must connect across neighboring reels from the left, so fixed payline patterns do not need tracking.

A Wild Symbol can replace regular symbols in qualifying combinations. The base game remains straightforward until Scatter Symbols redirect play into the Free Spins round.

Theme & Atmosphere

Day of the Dead imagery frames the game as a Festival rather than a purely Horror scene. Music references and decorated skulls emphasize celebration and remembrance.

Alcohol, Desert, and Festival details reinforce the setting through familiar objects and atmosphere. The tone stays colorful even though skull imagery supplies the central motif.

Features & Win Potential

The Wild Symbol supports ordinary ways combinations, while the Scatter Symbol controls access to Free Spins. Their jobs remain distinct during the base game.

Multiplier values attach to Wild Symbols during Free Spins, allowing a qualifying combination to receive a stronger return than the same arrangement in regular play.

High volatility Free Spins Multiplier Scatter Symbol Wild Symbol 96% RTP Free Spins Multiplier

Bonus & Free Spins

At least 3 Scatter Symbols award Free Spins, and larger triggering groups provide longer rounds. Scatter Symbols can also add further spins after the feature starts.

During Free Spins, Wild Symbols may appear with 2x, 3x, or 5x multipliers. These values apply to combinations containing the relevant Wild Symbol.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (High). The model is calibrated so the average return equals this slot's published RTP (96.04%), with wins capped at its top multiplier (3,000×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
