The Big Dog House is a five-reel, three-row slot from Pragmatic Play with a dog-themed design and a standard reel layout. The game uses paw scatter symbols to trigger the bonus round, where the feature can award between 9 and 27 free spins. In the demo version, players can play for free and practice before playing for real money.
During the base game, wild symbols can appear in standard, expanded 1x3 and colossal 3x3 forms, with multipliers of 2x or 3x attached. In the bonus game, wild multipliers remain sticky, while ghost wilds can land as substitutes and may also remove random sticky wilds from the grid before the next spin. This creates a feature set built around changing wild positions and multiplier combinations.
The bonus can also be modified by Biggie and Ghost Out effects. Biggie expands all wilds to fill the reel, while Ghost Out removes ghost wilds for the duration of the feature. The slot includes buy features, ante bets and super bets, along with autoplay and turbo spin controls.
