Play The Big Dog House

We’ve apparently outgrown the original kennel, because The Big Dog House from Pragmatic Play gives its multiplier Wilds considerably more floor space. Across a 5x3 grid and 20 paylines, we find the familiar canine cast, Bonus symbols on reels 1, 3 and 5, and Wilds that can arrive in standard, expanded or colossal sizes. 

Bonus spins add sticky Wilds, while Biggie and Ghost Out modifiers alter their size or remove the one symbol nobody wants hanging around. 

We’re back in the cheerful cartoon kennel that has defined The Dog House series since the original release. Bright colours, bold outlines and expressive dog portraits keep the mood light, even when the grid becomes crowded with giant doghouse Wilds. 

The regular symbols include four dogs, bones, collars and colourful card ranks. Red, green and blue paw symbols clearly separate the three possible bonus triggers, while the doghouse Wild grows from a standard square into a full reel block or a 3x3 structure. Animations emphasise those size changes without making the screen difficult to follow. The soundtrack maintains the playful tone, because apparently no kennel crisis can’t be improved by cheerful background music. 

The regular paytable begins with card ranks before moving through bones, collars and four premium dog symbols. We’ve arranged the values from the smallest to the largest potential payout. 

Special Symbols 

• Wild: The doghouse Wild substitutes for all regular symbols, but not for Bonus symbols. Wilds appear only on reels 2, 3 and 4 and carry random 2x or 3x multipliers. 
• Red Bonus: Three red paw Bonus symbols on reels 1, 3 and 5 activate the standard bonus spin round. 
• Biggie Bonus: A green Biggie Bonus symbol can combine with other Bonus symbols to activate the round with the Biggie modifier. 
• Ghost Out Bonus: A blue Ghost Out Bonus symbol can form part of the triggering combination and begin the round with the Ghost Out modifier. 
• Ghost Wild: The Ghost Wild appears only on reel 5 during bonus spins. The symbol substitutes for regular icons and carries a multiplier, but also removes one randomly selected sticky Wild. 

Standard, Expanded and Colossal Wilds 

Doghouse Wilds can appear in three sizes during the base game. The standard version occupies one position, the Expanded Wild covers an entire reel as a 1x3 symbol, and the Colossal Wild fills a 3x3 area. 

Every Wild receives a random 2x or 3x multiplier on each spin. The multiplier applies to every payline win involving that Wild. When several Wilds contribute to the same payline, their multiplier values are added together before the potential payout is calculated. 

Bonus Spin Trigger 

Bonus symbols appear only on reels 1, 3 and 5. Three red paw symbols activate the standard round, while a green Biggie or blue Ghost Out symbol can combine with other Bonus symbols to apply the matching modifier. 

Both special modifiers can activate together when the triggering symbols include Biggie and Ghost Out. Bonus symbols don’t appear after the round begins, so the feature can’t be retriggered. 

Bonus Spin Selector 

Before the round begins, a 3x3 grid determines the starting number of bonus spins. Each of the nine cells reveals a value of 1, 2 or 3. 

All nine values are added together, making the potential starting total range from 9 to 27 spins. We rather like this approach because the bonus count gets its own small ceremony rather than arriving as a number someone has quietly written on the kennel wall. 

Sticky Wilds 

During standard bonus spins, Wilds land only as 1x1 symbols on reels 2, 3 and 4. Once a Wild appears, the symbol remains fixed in place for the rest of the feature. 

Each sticky Wild carries a random 2x or 3x multiplier. That value is revealed when the Wild lands and remains unchanged while the symbol stays on the grid. Multiple sticky Wild multipliers can still combine when they contribute to the same payline. 

Biggie Modifier 

The Biggie modifier changes every Wild on reels 2, 3 and 4 into either an Expanded 1x3 Wild or a Colossal 3x3 Wild. Standard 1x1 versions no longer appear. 

These larger Wilds remain sticky during the bonus round, allowing one landing to cover a considerable portion of the reels. Multipliers continue to apply, with values from contributing Wilds added together on the same payline. 

Ghost Wild 

The Ghost Wild can appear on reel 5 during standard bonus spins or a round using only the Biggie modifier. The symbol substitutes for regular icons and carries its own random 2x or 3x multiplier. 

Whenever the Ghost Wild lands, one existing sticky Wild is chosen randomly and removed from its position. The Ghost Wild then leaves before the next spin. Building a useful grid and watching part of it vanish is certainly one way to test our emotional attachment to cartoon doghouses. 

Ghost Out Modifier 

Ghost Out prevents the Ghost Wild from appearing during the entire bonus feature. Sticky Wilds can therefore remain on the grid without being removed by the symbol on reel 5. 

When Biggie and Ghost Out activate together, Wilds on reels 2, 3 and 4 appear only in expanded or colossal sizes, while the Ghost Wild remains absent. This combination places the full focus on accumulating large sticky multiplier Wilds. 

We play The Big Dog House on 5 reels, 3 rows and 20 fixed paylines. Matching symbols must form combinations from left to right across adjacent reels, beginning with reel 1. 

Across online casinos, this reel structure is familiar, but the variable Wild sizes can change how much of reels 2, 3 and 4 becomes useful on any spin. Standard, expanded and colossal Wilds substitute for regular symbols, while their multipliers increase qualifying payline results. Bonus symbols remain limited to reels 1, 3 and 5 and don’t substitute for one another outside a valid trigger combination. 

For nearby mechanical territory, these three releases take expanding or multiplier Wilds in noticeably different directions. 

• Banana Twist: Twisting banana Wilds expand vertically and carry multipliers, with several participating Wild values added together when they support the same potential win. 
• Brute Force: Nolimit City uses stacked xNudge Wilds that move fully into view and build different multiplier values depending on which character lands. 
• Warrior Graveyard xNudge: Full reel Tombstone Wilds nudge into position, increase their multipliers and become especially important during the two bonus spin modes. 

The Big Dog House earns its extra adjective through scale rather than a total rebuild. Compared with many online slots that stretch a familiar series until the elastic gives up, we can at least see a meaningful change in the 1x3 and 3x3 Wilds. 

The Biggie modifier is the clear highlight because oversized sticky Wilds can reshape several paylines at once. The Ghost Wild is less charming. Watching a sticky Wild disappear feels like the kennel has started charging rent. We’d place this release with readers who already enjoy The Dog House format and want more visual impact from its multiplier mechanic. The structure remains familiar, but the larger Wilds stop the sequel from feeling like a new collar on the same dog.
