Two ten-spin feature modes
Boo's Booty Free Spins
Three Bonus symbols open Spooky Spins, while four open Phantom Spins with Ghost Wilds that lock and expand throughout the feature.
Product overview
Spooky Spins and Phantom Spins compared
Boo's Booty contains two related bonus modes. Landing three skull-candle Bonus symbols in the same spin activates 10 Spooky Spins. Landing four Bonus symbols activates 10 Phantom Spins, described in the game as Super Free Spins. Both use the Grave and Ghost Wild calculations established by the base game.
The defining Phantom addition is persistence. A Ghost Wild that lands during Phantom Spins locks in position until the end of the feature and expands on every spin. Spooky Spins do not add that locking behavior, but they retain the special multiplier relationship created when a Ghost expansion covers a Grave Wild.
Spooky trigger
Three Bonus symbols award ten spins
The Spooky Spins trigger uses three cream-colored skull candles marked Bonus. All three need to land in the same spin. The feature then starts with ten Free Spins and keeps the standard 5x5 cabinet and 15 left-to-right win lines.
Its feature information highlights the combination of expanding Ghosts and multiplier Graves. Ghost and Grave Wilds remain substitutes, but an overlap changes how their values are combined for the active spin.
Spooky overlap
A Grave changes the Ghost multiplier calculation
When a Ghost Wild expands over a Grave Wild in Spooky Spins, the Grave value affects the Ghost Wild multipliers present on that spin. The interaction gives one vertical expansion the ability to influence Wild values beyond a simple line-by-line addition.
The feature still evaluates paying combinations on the same 15 defined patterns. An enhanced multiplier only contributes where the expanded Wild participates in a valid line beginning from the leftmost reel.
Phantom trigger
Four Bonus symbols award ten Super Free Spins
Phantom Spins require one more Bonus symbol than Spooky Spins. Four appearing in the same spin activate ten Super Free Spins. The trigger artwork places the four skull candles beside a tall Ghost Wild, previewing the persistence mechanic.
Phantom follows the Spooky multiplier rules, so Grave values and Ghost expansion continue to interact. The difference is that a Ghost landing is remembered rather than cleared before the next feature spin.
Locked Ghosts
Each landed Ghost remains until the feature is complete
A Ghost Wild in Phantom Spins locks in its original position. It stays on the reel for all remaining spins and expands upward every time. Its row-based multiplier therefore repeats, while fresh symbols and possible Grave Wilds change around it.
Additional Ghost Wilds can lock on other reels, respecting the one-Ghost-per-reel limit. Persistent vertical coverage can then intersect several line patterns and create repeated opportunities for Grave overlap.
