The Dog House Multihold is an online slot developed by Pragmatic Play and released on February 27, 2023. It is another instalment in the popular The Dog House series, retaining the familiar backyard setting while introducing a Free Spins feature that can expand across four separate playing grids.
The game uses five reels, three rows and 20 fixed paylines. It has a standard theoretical RTP of 96.06%, high volatility and a maximum advertised payout of 9,000× the stake.
Its defining feature is the Multihold bonus, where sticky multiplier Wilds can remain active across several grids as players unlock additional stages of the Free Spins feature.
Theme and Visual Design
The Dog House Multihold returns to the colourful suburban backyard familiar from the original game.
The reels are surrounded by green grass, wooden fences and houses, creating a cheerful neighbourhood atmosphere.
Several recognisable dog breeds appear among the premium symbols, accompanied by bones and collars.
The lower-paying symbols consist of traditional playing-card ranks: 10, J, Q, K and A.
The rottweiler is the highest-paying regular symbol, awarding up to 37.5× the stake for a full five-symbol payline.
A dog house acts as the Wild symbol, while a paw print marked Bonus serves as the Scatter.
The base game looks very similar to the original The Dog House, with the main differences appearing during Free Spins.
Gameplay and Paylines
The Dog House Multihold features five reels, three rows and 20 fixed paylines.
Winning combinations are formed by landing at least three matching symbols on consecutive reels, beginning with the leftmost reel.
The game follows a traditional payline structure rather than using Megaways, cluster pays or cascading reels.
Premium symbols include several dog breeds, bones and collars.
The rottweiler offers the highest regular symbol payout, while the lower-paying card symbols provide smaller wins.
The base game focuses on multiplier Wilds and the possibility of triggering the Free Spins bonus.
There are no expanding reels or additional collection mechanics during regular spins.
Multiplier Wild Symbols
Wild symbols are represented by dog houses.
They appear on reels two, three and four and substitute for regular paying symbols to help complete winning combinations.
Each spin assigns Wilds on the same reel a multiplier of either 2× or 3×.
When a Wild contributes to a winning payline, its multiplier increases the value of that win.
If more than one Wild contributes to the same winning combination, their multipliers are added together.
For example, a winning payline containing a 2× Wild and a 3× Wild receives a combined 5× multiplier.
This mechanic can increase regular payouts and becomes especially important during the Free Spins feature.
Scatter Symbols
Scatter symbols feature a paw print marked Bonus.
They appear on reels one, three and five during the base game.
Landing three Scatters triggers the Free Spins feature and awards an additional payout of 2× the stake.
The bonus begins with seven free spins.
Unlike the original The Dog House, the Multihold version introduces several playing grids that can be unlocked during the bonus.
Multihold Free Spins
The Free Spins feature is the main attraction of The Dog House Multihold.
It begins with seven free spins and four separate playing grids.
Only the first grid is unlocked when the feature starts.
To unlock the next grid, players must collect three Scatter symbols.
During Free Spins, Scatters can appear on all reels, but only on the last unlocked grid.
Whenever a new grid is unlocked, the game awards one, two or three additional free spins.
This creates opportunities to extend the bonus while progressing through the available grids.
The feature can eventually expand to four active playing grids.
However, unlocking every grid is not guaranteed.
Sticky Wilds Across Multiple Grids
Sticky Wilds are the defining mechanic of the Multihold bonus.
During Free Spins, Wild symbols that land on the last unlocked grid become sticky.
Once a Wild becomes sticky, it remains in its position for the rest of the bonus.
The Wild also retains its multiplier.
When another grid is unlocked, the sticky Wilds from the previous grid are copied to the newly unlocked grid.
They also remain active on the previous grid.
For example, if two sticky Wilds have accumulated on the first grid, unlocking the second grid transfers those Wild positions to the second grid while keeping them on the first.
This process can continue as additional grids become available.
The result is a bonus where Wild positions can be duplicated across several playing areas.
As more grids become active, the number of potential winning combinations can increase considerably.
However, sticky Wilds do not guarantee payouts.
Matching paying symbols must still appear in the appropriate positions to form winning paylines.
Unlocking All Four Grids
The Multihold feature can expand from one active grid to four.
Each new grid requires the collection of three additional Scatter symbols on the most recently unlocked grid.
The progression works as follows:
| Stage | Active Grids | Requirement |
|---|---|---|
| Start | 1 | Free Spins activated |
| Stage 2 | 2 | Collect 3 Scatters |
| Stage 3 | 3 | Collect 3 more Scatters |
| Stage 4 | 4 | Collect 3 more Scatters |
Each grid unlock awards between one and three additional free spins.
The most valuable bonus outcomes generally depend on collecting sticky Wilds early and unlocking additional grids while enough spins remain.
However, the feature can also end before all four grids are unlocked.
The outcome depends entirely on the randomly generated symbols.
Bonus Buy
The Dog House Multihold includes a Bonus Buy option.
For a cost of 100× the selected stake, players can purchase direct access to the Free Spins feature.
For example, at a base stake of €1, the purchase costs €100.
The purchased bonus follows the same Multihold mechanics as a naturally triggered feature.
It begins with seven free spins and provides opportunities to unlock additional grids.
However, buying the bonus does not guarantee that all four grids will be unlocked.
It also does not guarantee a payout greater than the purchase price.
Bonus Buy availability depends on the casino and applicable gambling regulations.
RTP and Volatility
The Dog House Multihold has a standard theoretical RTP of 96.06%.
Pragmatic Play also offers alternative RTP configurations.
| RTP Version | RTP |
|---|---|
| Standard | 96.06% |
| Alternative 1 | 95.14% |
| Alternative 2 | 94.06% |
Players should verify the active RTP within the game’s information menu before playing.
The Dog House Multihold is classified as high volatility.
Its reported hit frequency is 24.21%, while the theoretical bonus frequency is approximately one in 175.54 spins.
These figures represent long-term mathematical averages rather than guaranteed outcomes.
Because much of the game’s payout potential is concentrated in the Free Spins feature, individual sessions can vary considerably.
Maximum Win and Betting Range
The Dog House Multihold offers a maximum advertised payout of 9,000× the stake.
The largest potential wins depend on accumulating sticky multiplier Wilds and unlocking additional grids during Free Spins.
The published probability of achieving the maximum payout is approximately one in 5,266,088 spins.
The referenced betting range is 0.20 to 100 per spin.
Betting limits may vary depending on the casino, currency and game configuration.
The maximum payout is a theoretical limit rather than an expected result.
Mobile Compatibility
The Dog House Multihold is available on compatible desktop computers, smartphones and tablets.
Its traditional five-reel layout works well on smaller screens during the base game.
The Free Spins feature becomes more visually complex as additional grids are unlocked.
However, the familiar dog symbols and multiplier Wilds remain easy to recognise.
Players using smaller devices may find the four-grid bonus busier than the original game’s single-grid Free Spins feature.
Availability and performance depend on the casino platform and supported device.
The Dog House Multihold vs The Dog House
The Dog House Multihold builds on the original The Dog House by introducing a more elaborate Free Spins feature.
Both games use five reels, three rows and 20 fixed paylines.
They also share the same backyard theme, dog symbols and multiplier Wild mechanics.
The original The Dog House focuses on a single-grid Sticky Wild Free Spins bonus.
The Dog House Multihold expands this concept across up to four grids.
When new grids are unlocked, existing sticky Wilds are duplicated across the available playing areas.
This creates additional opportunities for winning combinations.
The Multihold version also increases the maximum advertised payout from 6,750× to 9,000× the stake.
However, the original game remains simpler to understand and does not require players to progress through several bonus stages.
The Dog House Multihold vs The Dog House Megaways
The Dog House Megaways takes a different approach to expanding the original formula.
It replaces fixed paylines with the Megaways mechanic, offering up to 117,649 ways to win.
It also introduces two selectable Free Spins modes: Sticky Wilds and Raining Wilds.
The Dog House Multihold retains the traditional five-reel layout but introduces multiple playing grids during the bonus.
While Megaways focuses on changing reel configurations and different Wild behaviours, Multihold focuses on accumulating and duplicating sticky Wilds across additional grids.
Both games offer more complex bonus mechanics than the original The Dog House.
The preferred version ultimately depends on whether players enjoy changing reel configurations or progressive multi-grid features.
Slotinia’s Verdict on The Dog House Multihold
The Dog House Multihold is a creative continuation of Pragmatic Play’s popular dog-themed slot series.
Its greatest strength is the Multihold Free Spins mechanic.
The ability to accumulate sticky multiplier Wilds and carry them into additional grids creates opportunities for increasingly valuable winning combinations.
The game also retains the straightforward base-game structure that helped make the original The Dog House popular.
However, the base game offers very little that distinguishes it from the original release.
Most of the new gameplay is concentrated in the Free Spins feature.
The high volatility also means that significant payouts can be infrequent, particularly when the bonus ends before several grids have been unlocked.
Overall, The Dog House Multihold is an interesting variation on the original Sticky Wild formula, offering a more elaborate bonus without changing the familiar base-game experience.
Responsible Gambling
The Dog House Multihold is a high-volatility game of chance involving financial risk.
Its RTP, bonus frequency and maximum advertised payout do not guarantee any particular outcome.
The Bonus Buy option requires a substantial upfront payment and does not guarantee a profitable result.
Players should verify the active RTP, understand the Multihold mechanics and establish a budget before playing.
Gambling should always be treated as entertainment rather than a source of income.
