The Big Dog House: Colossal Wilds and Ghosts

The Big Dog House is a Pragmatic Play slot that the studio presents as the return of its canine crew. It is built entirely around wild symbols: every wild carries a multiplier, wilds come in three sizes, and the free spins round adds ghost wilds that work against the sticky wilds you have collected.

In the base game the new parts are expanded and supersized wilds. In the bonus game, ghost wilds join in, and two modifiers called Biggie and Ghost Out can change how the round plays.

Pragmatic Play's own game page lists one headline figure, an RTP of 96.53%. It does not publish volatility, a max win, a bet range or the grid layout, so those are not covered here.

Pragmatic Play lists the RTP of The Big Dog House at 96.53% under its basic game info. That is the theoretical return over a very large number of spins, not a figure that says anything about a single session.

The free spins round awards 9 to 27 free spins, decided by nine mini reels that spin before the round starts. Wild multipliers are 2x or 3x throughout, and ghost wilds in the bonus carry multipliers of up to 3x.

Volatility, max win, minimum and maximum bet, and the number of paylines are not given on the provider's page. Check the game's own information screen for them before playing.

Every wild in The Big Dog House carries a 2x or 3x multiplier, in the base game and the bonus game alike. Pragmatic Play says these multipliers combine for bigger payouts when more than one wild is involved.

A wild can land in one of three forms: a normal single symbol, an expanded 1x3 wild, or a colossal 3x3 symbol. The larger forms cover more positions on the grid, so the size a wild lands in changes how much of the screen it substitutes on.

The provider does not spell out whether combined multipliers are added or multiplied together, so this review does not assume either. The demo shows the combined figure on screen when two or more multiplier wilds take part in a win.

Three paw scatters trigger the bonus game. Before the free spins begin, nine mini reels spin to decide how many spins are awarded, with a range of 9 to 27.

The spread between the lowest and highest award is wide. A round starting with 27 free spins has three times as many spins as one starting with 9, and because wilds are sticky in this round, the extra spins give more chances for wilds to build up on the grid.

Pragmatic Play describes the trigger as landing three paw scatters. Its page does not mention a bonus buy option, so this review does not describe one.

All wild multipliers are sticky during the free spins, so a wild that lands stays where it is with its 2x or 3x value for following spins. The longer the round runs, the more spins there are for new wilds to join them.

Ghost wilds are the counterweight. They carry multipliers of up to 3x and substitute for any symbol, but they also remove random sticky wilds from the grid before the next spin.

That makes every ghost wild a mixed result. It helps the spin it lands on as a substitute with a multiplier, then takes away part of what the round has built. Whether a round grows or shrinks depends on how often ghosts appear against how often new sticky wilds land.

The bonus game can trigger with up to two modifiers. Pragmatic Play's page does not explain how a modifier is attached to a round, so this review only describes what each one does.

Biggie makes every wild expand to fill the reel. In a round where wilds are sticky, each expanded wild then stays in place as a full reel of wild.

Ghost Out removes ghost wilds for the duration of the feature. Ghost wilds are the only thing Pragmatic Play's page says removes sticky wilds, so a Ghost Out round takes that threat away. A round with both modifiers combines full-reel wilds with no ghost wilds to take them away.

The free demo of The Big Dog House on this page runs on play credits. It is the place to see the three wild sizes land in the base game and to check how two multiplier wilds combine in the win display.

In the bonus, watch the nine mini reels to see the spin count, then follow the balance between sticky wilds and ghost wilds. Note which rounds arrive with Biggie or Ghost Out and how the grid differs.

Read the information screen for the RTP, bet range and max win of the version in front of you. A demo shows how the features behave; it does not predict any future result. The game is intended for players aged 18 and over.

How many free spins can you get in The Big Dog House?

Between 9 and 27. Three paw scatters trigger the bonus game, and nine mini reels spin first to set the number of free spins. During the round all wild multipliers are sticky, while ghost wilds with multipliers of up to 3x can land and remove random sticky wilds before the next spin.

What do ghost wilds do in The Big Dog House?

Ghost wilds appear in the bonus game, carry multipliers of up to 3x and substitute for any symbol. They also remove random sticky wilds from the grid before the next spin, so they help the spin they land on but can take away wilds the round has built up. The Ghost Out modifier removes them.

What are the Biggie and Ghost Out modifiers?

They are two modifiers the bonus game can trigger with, and a round can have both. Biggie makes all wilds expand to fill the reel. Ghost Out removes ghost wilds for the whole feature, and with them the wilds that remove sticky wilds. Pragmatic Play's page does not explain how a modifier is attached to a round.
