The Big Dog House Slot (Pragmatic Play)

The Big Dog House slot has 5 reels, 3 rows and 20 fixed paylines. Landing 3, 4 or 5 matching symbols from left to right, starting from reel 1 and across any of the 20 paylines will constitute a winning combination. Only the highest win per payline will be awarded.

With a minimum bet of 20p a spin, the most you can play for in the UK is £5 a spin (or up to £2 if you’re 18-24): use the plus and minus buttons to change your stake. Non-UK players can benefit from 2 Turbo Mode settings and Autoplay.

The Big Dog House RTP rate is 96.53%: this is significantly higher than the slots average of 96%. As expected, Pragmatic Play has created 95.45% and 94.48% RTP variants so check which rate you’re playing with within the Paytable at your chosen slot site. Based on a £20 balance playing at 20p a spin, below is the number of expected spins you’ll play before running out of funds for each RTP variant:

• 96.53%: 2,854 spins
• 95.45%: 2,176 spins
• 94.48%: 1,794 spins

Medium volatility, a winning combination will land every 3.75 spins on average as the hit frequency rate is 26.67%. When it comes to triggering any of the 3 free spins features, it will take approximately 188.44 spins.

Finally, The Big Dog House benefits from 15,000 x bet max wins. Hitting the max win will occur every 1 in 17,953,321 spins whilst winning 1,000 x bet (or more) or 5,000 x bet (or more) will occur every 33,082 or 9,871,668 spins, respectively.

With a dogs/animals theme, The Big Dog House slot follows from several ‘The Dog House’ games including The Dog House (May 2019), The Dog House Megaways (August 2020) and The Dog House Muttley Crew (October 2024).

In this instalment, the canine crew is back as you head to an idyllic suburban setting. With cute houses, white picket fences and clear, blue skies in the backdrop, the reels are encased by a dog house. The graphics are bold and the soundtrack is playful and light-hearted.

On the reels, you’ll see low-value A, K, Q, J and 10 symbols. The higher-value symbols include a dog bone, a dog collar and 4 dogs: dachshund, pug, shih tzu and rottweiler. The best paying symbol is the rotteweiler: 5 across a payline awards 37.5 x your total bet.

There is also a Dog House Wild symbol that substitutes for all paying symbols above, look out for 3 different Paw Print Bonus Scatters landing on reels 1, 3 and 5: more on these below.

The Big Dog House Mobile

The Big Dog House is compatible with mobile, desktop and tablet devices. With HTML5 technology used, it will detect the device you’re playing on and serve the correct version. If playing on an iOS or Android smartphone, you’ll play in Portrait Mode.

The Big Dog House comes with tumbles and wild multipliers up to 100x. With a choice of 6 free spins and wild multiplier options, there is a Super Free Spins feature where you can build up the non-resetting total multiplier.

Wild Multipliers

As mentioned, the Dog House Wild lands on the 3 middle reels and substitutes for paying symbols. Landing 1x1 (normal), 1x3 (expanding) or 3x3 (colossal) in size, it will also contain a 2x or 3x multiplier. Several Dog House Wilds can land on the reels with their multipliers added to each other, for a potential 126x multiplier.

Free Spins

The Big Dog House comes with 4 free spins modes, triggered by Paw Print Bonus Scatters landing on reels 1, 3 and 5 simultaneously during a base game spin.

Before any free spins mode begins, you’ll come across a 3x3 grid which spins to reveal 1, 2 or 3 free spins in each cell. The numbers in each cell are added together for a free spins total: you’ll play each free spins mode with 9 to 27 free spins.

During the free spins, a Ghost Wild symbol can appear on reel 5. Substituting for all symbols with a multiplier of 2x or 3x, a random sticky wild on any size on the reels is chosen and unsticks. Below are details of each mode.

To trigger the Free Spins feature, you need Red Paw Print Bonus Scatters on reels 1, 3 and 5, you’ll benefit from sticky Dog House Wilds with multipliers of 2x or 3x.

With the Biggie Free Spins feature, you need 1 Green Paw Print Bonus Scatter and 2 Red Paw Print Bonus Scatters on reels 1, 3 and 5, it comes with the Biggie modifier. All Dog House Wilds appear 1x3 in size, which are sticky and come with 2x or 3x multipliers.

Finally, the Ghost Out Free Spins feature is activated by landing 1 Blue Paw Print Bonus Scatter and 2 Red Paw Print Bonus Scatters on reels 1, 3 and 5. No Ghost Wilds appear on reel 5, meaning more sticky wild multipliers.

You can also trigger Biggie Ghost Out Free Spins feature with both the Biggie and Ghost Out modifiers, meaning no Ghost Wilds and 1x3 Dog House Wilds. Finally, you cannot win extra free spins in any of the modes.

Ante Bets, Super Spins & Bonus Buy

The Big Dog House Slot

Rating: 3.7/5

The Big Dog House builds on its predecessors with 1x3 and 3x3 wilds, 2 modifiers in the free spins and higher max win potential of 15,000 x your total bet.

Chris Taylor

With previous The Dog House games being so popular (especially in the UK), The Big Dog House slot offers more of the same with some twists. The base game gameplay is the same with wild multipliers up to 3x that can combine up to 126x. However, Dog House Wilds can appear 1x1, 1x3 or 3x3 in size which is different from its predecessors.

The difference is in the free spins as there are 4 modes effectively. With 3 different Dog House Wild sizes, you’ll play the regular free spins or with 1 or 2 modifiers: the Biggie modifier only has 1x3 or 3x3 Dog House Wilds whilst the Ghost Out modifier means no Ghost Wilds so Dog House Wilds are not removed from the reels. If you’re lucky enough to play the Biggie Ghost Out free spins, you’ll benefit from both modifiers.

With 15,000 x bet max wins, The Big Dog House is the highest paying slot game in the series (The Dog House Megaways offers 12,305 x bet max win potential). However, the RTP rate in the Megaways version is higher (96.55%) than in this instalment (96.53%):

In summary, The Big Dog House offers similar gameplay to its predecessor with different sized wilds and 2 modifiers in the free spins. Add in the higher max win potential and you have a better game, in theory. However, it doesn’t quite do enough to earn a place on my list of the 10 best animal-themed slots:
