Hollywoof Slot by GameArt

Sunny Hollywood Boulevard, but the movie stars are dogs. Palm trees and art-deco columns line a deep-blue billboard reel set, paw-print stars dot the walk of fame below, and a glowing pink-and-orange "HOLLYWOOF" sign hangs over the top in clear parody of the real thing. The high pays are all glammed-up celebrity canines: a rapper dog in a cap and shades dripping with bling, a suave wolf in a purple tuxedo, a blonde bombshell poodle styled after Marilyn, and a cool dog hiding behind sunglasses. The low pays are neon Hollywood-sign card royals, A down to 9, lit up in Tinseltown blues, golds and pinks.

The bone Wild is where the math lives. It substitutes for everything but the Scatter, and most of them land carrying a multiplier up to x5. When a bone sits on a winning line it multiplies that line's pay, and here's the part that matters: drop two or more bones on the same payline and their multipliers add together, not multiply. A x4 and a x3 on one line means x7 on that win. A bone with no value printed on it just counts as x1.

Three, four or five Scatters award 8, 10 or 15 free spins, and every win during the round is doubled flat. Land 3 more Scatters mid-round and you retrigger, stacking spins up toward a 100-spin ceiling. The reason the bonus runs so much hotter than the base game is the Free Spin Super Stacks: each spin, a randomly chosen symbol gets super-stacked across adjacent reel positions, with the picked symbols flagged in the top corners before the reels drop. Fill a few reels with the same stacked celebrity dog and big synchronized lines fall far more often than 10 paylines would normally allow, doubled wins compounding on top. If you'd rather skip the Scatter hunt, the Buy Bonus drops you straight into the free spins, no gamble and no jackpots attached to it.
