The Big Dog House Features & Mechanics
Wild Features
Wild symbols substitute for all standard symbols except Bonus symbols and appear on reels 2, 3, and 4. They can land in three sizes:
- 1×1 (Standard)
- 1×3 (Expanded)
- 3×3 (Colossal)
Each Wild carries a random multiplier of 2x or 3x. When multiple Wilds contribute to a win, their multipliers are added together before being applied to the total pay out.
Bonus Triggers
Bonus-related symbols appear on reels 1, 3, and 5:
- Bonus Symbol – Landing three triggers the Free Spins feature.
- Biggie Bonus Symbol – When part of a triggering combination, activates Free Spins with the Biggie modifier.
- Ghost Out Bonus Symbol – When included in the trigger, activates Free Spins with the Ghost Out modifier.
Free Spins Feature
Before the Free Spins round begins, a 3×3 grid determines the total number of spins awarded. Each cell reveals 1 to 3 spins, which are added together to form the starting total.
During Free Spins:
- Wilds become sticky and remain on the reels for the duration of the feature.
- Each Wild retains its multiplier value once revealed.
- Wilds appear only in standard 1×1 size unless modified by feature conditions.
The Big Doghouse Mechanics
A special Ghost Wild can appear on reel 5 during Free Spins. This symbol substitutes for all regular symbols and carries a 2x or 3x multiplier. When it lands, it removes a random sticky Wild from the grid before the next spin, adding an element of risk.
Feature modifiers alter gameplay:
- Biggie Modifier – All Wilds land as 1×3 expanded symbols.
- Ghost Out Modifier – Ghost Wilds do not appear.
- Combined Modifier – Expanded Wilds are active, and Ghost Wilds are removed.
Free Spins cannot be retriggered.
Special Bets
Players can select from a range of enhanced betting options that alter gameplay. These include modes that guarantee or increase the chance of Wilds appearing, as well as Ante Bet options that significantly boost the probability of triggering Free Spins with specific modifiers.
Buy Feature
The Free Spins feature can be purchased directly:
- 100x bet – Standard Free Spins
- 200x bet – Biggie or Ghost Out Free Spins
- 500x bet – Combined Biggie + Ghost Out Free Spins (no Ghost Wilds)
Conclusion
The Big Dog House builds on the success of the original Dog House formula, introducing larger Wild variations and additional modifiers to create a more dynamic experience. The combination of expanding and colossal Wilds, along with multipliers, offers strong potential for big line wins.
The Free Spins feature remains the main highlight, with sticky Wilds driving most of the game’s win potential. The added Biggie and Ghost Out modifiers introduce variety, giving players different ways to approach the bonus and increasing replay value.
