A Pragmatic Play slot where free spins rounds transform sticky wilds into your advantage, with 96.53% RTP and a mix of smaller and bigger wins across 20 paylines.

How wilds boost your payline wins. The Big Dog House is a five-reel, three-row dog-themed slot with 20 fixed paylines. Wild symbols land on reels two to four and carry a random multiplier of either two or three times your bet—multipliers stack when several wilds appear on the same payline. The game mixes smaller and bigger wins across its rounds, so you'll encounter both frequent and occasional payouts as you play.
The right fit for patient players. This slot suits players who enjoy watching symbols build wins gradually and who have a budget for medium-volatility games. At a minimum stake of 20p and maximum of five pounds, you can pace your play to match your comfort level. The sticky wild mechanic in free spins rewards longer bonus rounds, so it suits players who like features to shape a session more than those hunting quick base-game wins.
Free spins where wilds stick and lock. Free spins form the heart of how this slot plays. You spin a barrel to reveal how many free spins you'll receive, and the wilds that land during this round lock in place, keeping their multiplier for every spin. A ghost wild on reel five can unstick those locked wilds, adding a layer of unpredictability to how your bonus unfolds and whether sticky wilds stay or move away.
Full storyThe key numbers that shape how the game plays and what you might win.
A round runs the same way every time, with just a few moments where your luck changes
How do wilds behave in free spins? Free spin count comes from a 3x3 barrel grid where you reveal 1, 2 or 3 values that add together. Wilds on reels 2–4 become sticky, keeping their random 2x or 3x multiplier. Ghost Wild on reel 5 can remove sticky wilds.
Expanded over normal wilds. Wilds on reels 2–4 land only as 1x3 expanded or 3x3 colossal size, never plain. They stick for the whole round and keep their 2x or 3x multiplier. Ghost Wild still active on reel 5 to unstick them.
No escape from permanent wilds. Sticky wilds on reels 2–4 become permanent and cannot be removed. Ghost Wild does not appear on reel 5, so locked-in wilds stay put for every remaining spin of the round.
The Big Dog House at maximum power. Wilds land only as expanded or colossal and turn permanent immediately. No Ghost Wild appears on reel 5. Both the size and the stickiness of these wilds carry through to the final spin.

Return to player is an average calculated over a vast number of spins across all players. The 96.53% figure shown applies only to the standard game at this slot. This means for every 100 pounds staked, you would see roughly 96.53 pounds returned in winnings over an extremely large sample of play.
The unpredictable trigger. Free spins arrive at random intervals that no player can forecast. The bonus round might come early in your session, or you might spin the base game for hours without triggering it.
Your session stays unique. Each session plays out differently. The 96.53% RTP describes long-term behaviour across millions of spins, not what happens in your next hour at the reels.
The Big Dog House maximum stays rare. The maximum win of £75,000 sits at the ceiling of what this game can pay. It lands so rarely that you should not count on seeing it during regular play.
