Product overview

Grave Wild values and line calculations

The Grave Wild is a compact tombstone symbol with its multiplier printed in cyan and yellow. Five values are available: x2, x3, x4, x5 and x10. Up to five Grave Wilds may appear in one spin, allowing several reels or positions on the 5x5 grid to carry multiplier substitutions at the same time.

A Grave Wild replaces paying symbols when it sits on a valid line. If one participates, its value multiplies the prize of that line. When several Grave Wilds participate in one line, the values are added together. The interaction becomes more complex if an expanding Ghost Wild covers one or more Grave Wild positions.

Five values

The tombstone set ranges from x2 to x10

The complete Grave Wild set contains x2, x3, x4, x5 and x10 symbols. The artwork uses the same RIP tombstone frame for every version while changing the central number. This consistent silhouette makes all five recognizable as one Wild family.

Because the values are visible before a line result is presented, the multiplier contribution can be read directly from the grid. Lower and higher Grave values can appear together, and their placement determines which of the 15 line paths can use them.

Substitution rule

Every Grave Wild can replace a paying symbol

Grave Wilds substitute for all paying symbols. A line still needs to start on the leftmost reel and continue across adjacent reels, but a tombstone can fill a missing position along that path. Its multiplier is then attached to the line prize.

Up to five Grave Wilds can land in a spin, so the feature is not limited to one substituted position. Separate lines can use different Grave symbols, while one line may travel through more than one multiplier tombstone.

Additive values

Multiple Grave multipliers combine by addition

If a winning line uses several Grave Wilds, their printed values are added. An x2 and x4 produce a combined x6 multiplier for that line. An x5 and x10 would produce x15. The rule keeps the combined value readable as a sum of the participating tombstones.

This calculation applies per winning line. A Grave symbol may influence more than one line if its reel position belongs to several of the 15 defined patterns, and the multiplier is applied to each qualifying line prize it supports.

Ghost overlap

An expanding Ghost can cover Grave positions

Ghost Wilds expand upward from their landing row. If that expansion crosses one or more Grave Wilds, the covered Grave values are added together and then combined with the Ghost multiplier through the special overlap calculation. The Ghost height therefore matters alongside the tombstone values.

The mixed effect links vertical coverage with fixed line multipliers. A tall Ghost may cover several rows, but only the Grave symbols inside its expansion contribute their values. The resulting Wild still needs to participate in a valid left-to-right line.

Feature context

Spooky and Phantom Spins increase the importance of overlap

Spooky Spins are activated by three Bonus symbols and provide ten spins. Their rules emphasize Ghost and Grave interaction, including the multiplier change that occurs when an expanding Ghost covers a Grave Wild.

Phantom Spins use the same foundation but lock every landed Ghost Wild until the feature ends. A locked Ghost expands on each spin, giving later Grave Wild landings repeated opportunities to sit beneath persistent spectral coverage.
