The Big Dog House

Base Game – Paytable / Math

this slot runs a familiar 5×3 grid with 20 paylines. Symbol tiers split into three brackets: five lower-paying card ranks pay 1.25x to 2.50x for five-of-a-kind; two mid-range bones and collars deliver 5x to 7.5x; four premium doggies range from 10x up to 37.5x.

Volatility sits at medium-high (3.5 out of 5 on Pragmatic’s scale). Three RTP settings are available: 96.53% (default), 95.45%, and 94.48%. Hit frequency lands at 26.67% – roughly one win every 3.75 spins. Free Spins trigger around once per 188.44 spins.

Wild Symbols – Three Sizes / Stacking Multipliers

The dog house Wild substitutes for every regular symbol on reels 2, 3, and 4. Each Wild lands in one of three forms: a standard 1×1, an Expanded 1×3, or a Colossal 3×3 block. Every Wild carries a random multiplier of either 2x or 3x, applied to each payline it completes. When multiple Wilds land on the same payline, multipliers stack by adding up – a sharp tool when the grid opens up.

Free Spins – Sticky Wilds / Ghost Wild Twist

Paw-print Scatter symbols on reels 1, 3, and 5 trigger Free Spins when three land together. Two special Scatter variants – the green Biggie Bonus and blue Ghost Out Bonus – apply modifiers if included in the winning combination.

Spin count is determined by a 3×3 grid that reveals digits 1, 2, or 3 in each cell. All nine figures are added together to set your starting Free Spins count.

During the bonus round, Wilds lock in place as 1×1 blocks and stay sticky until the round ends – except when the Ghost Wild appears on reel 5. The Ghost Wild substitutes like a regular Wild with multipliers, but comes with a cost: it forces one random sticky Wild currently on screen to unstick and vanish. The Ghost Wild itself does not stick.

Modifiers shift the round’s behavior: Biggie forces Wilds to land only as 1×3 Expanded or 3×3 Colossal blocks, removing the 1×1 size. Ghost Out removes the Ghost Wild entirely, so it cannot appear on reel 5. Both modifiers can be active together.

Ante Bets / Feature Buys – Full Menu

this slot packs twelve side options: four Ante Bets that boost Free Spins trigger odds, four Super Spins that guarantee Wilds in base game, and four direct feature buys. No features are locked behind a paywall.

Presentation / Feel

The background has been tweaked slightly, but the overall vibe remains locked to the 2019 original. If you’ve spent time with The Dog House before, the slot feels immediately at home. Pragmatic’s cartoon style is all here: goofy charm, light colours, no surprises on the visual front.
