Base Game / Reels / Symbols
5×3 grid, 20 ways to win. Hit rate sits at 26.67%, with wins landing roughly 1 in 3.75 spins. Free spins trigger once every 188.44 spins on average.
Paytable splits into three tiers. Card ranks (lowest tier) pay 1.25x to 2.50x for five-of-a-kind. Mid-range symbols (bones, collars) pay 5x to 7.5x. Premium dogs deliver 10x to 37.5x.
Wild Symbols / Multipliers / Sizes
Dog house Wilds land on reels 2, 3, and 4 only. Each Wild comes with a random 2x or 3x multiplier. When multiple Wilds hit the same payline, multipliers add together.
Three Wild sizes change payoff structure. Standard 1×1 covers one cell. Expanded 1×3 covers three cells vertically. Colossal 3×3 covers nine cells at once. Base game mixes all three sizes across spins.
Free Spins / Sticky Wilds / Ghost Unstick
Three paw-print Scatters on reels 1/3/5 trigger free spins. Spin count uses an unusual method: a 3×3 grid reveals nine random numbers (each 1, 2, or 3), totaling your starting spin count.
During free spins, all Wilds land as 1×1 size only and stick to their positions for the remainder of the round. Ghost Wild symbol (reel 5 only) acts like a regular Wild with multipliers but removes one random sticky Wild from the grid when it lands. Ghost does not stick itself.
Two special Scatter variants modify the round. Biggie forces Wilds to land only as 1×3 Expanded or 3×3 Colossal blocks. Ghost Out removes the Ghost Wild symbol entirely, preventing unsticks. Both modifiers can activate together in a single free spins round.
