The Dog House slot: the game that made sticky wilds a trademark

How the base game plays

Five reels, three rows, twenty fixed lines and a kennel-yard theme with a bulldog, a boxer, a dachshund and a pug as the premium symbols. The wild is a doghouse, and it lands on the three middle reels only. Every wild that takes part in a win carries a multiplier of two or three times, and when several wilds sit on one line their multipliers multiply each other rather than add up. That detail is the whole game: a line win with two multiplied wilds pays several times what the paytable suggests, and it is why the base game feels slower than the numbers say and then pays in bursts.

The free spins and the sticky wilds

Three paw-print scatters on the middle reels open the bonus, and you pick the free spins with sticky wilds. From that point every wild that lands stays in place until the round ends, still carrying its multiplier. The first few spins are usually quiet; the fun begins when three or four sticky wilds cover the middle reels and every line crossing them is multiplied several times over. The bonus cannot be retriggered, so the count of spins you get at the start decides the outcome, and that is where the volatility comes from: a bonus with one sticky wild pays back the stake, a bonus with five can approach the top prize.

Numbers to play by

The declared RTP is 96.51%, which is above the middle of the Vavada slots room. The maximum win of 6750x is reachable only from the free spins with a wall of sticky multiplied wilds. In practice the game rewards patience at a small bet: the base game will drain a bankroll that is sized for a five-minute session, and the bonus is what you are paying for. A bet you can afford to spin a couple of hundred times is the right size.

Demo and the real thing

The demo above is the studio's own launcher, so the maths, the paytable and the bonus are identical to the paid version; only the balance is play money. Use it to see how often the multiplied wilds hit before you register. At Vavada the game opens from the Hit tab, and new accounts get 100 free spins that can be used in slots from this room; the details are on the bonuses page. If you like the format, the same studio's Big Bass Splash takes the collect-and-multiply idea in a different direction.
