The Dog House
The Dog House became one of Pragmatic Play's defining slots by making every Wild more important than a simple substitute. Each kennel Wild carries either a 2x or 3x multiplier, and the Free Spins round can lock those Wilds permanently into the three central reels. What begins as a straightforward twenty line game can therefore develop into a bonus where several fixed multiplier positions repeatedly influence the same paylines until the final spin. The Dog House uses five reels, three rows and 20 fixed paylines. Bets range from 0.20 to 100 and the game has high volatility, with a maximum win of 6,750x the total bet. The published hit frequency is 27.55%, the maximum win probability is approximately 1 in 8,333,333,333 spins and the Free Spins feature occurs on average once every 180.47 spins. The kennel is the Wild and appears exclusively on reels two, three and four. Every Wild receives either a 2x or 3x multiplier and substitutes for all regular paying symbols. When a Wild participates in a winning payline, its multiplier is applied to that line win. If several Wilds from different reels contribute to the same winning line, their multiplier values are added together rather than multiplied. This additive behaviour means the three central reels can produce a combined Wild multiplier of up to 9x on one payline when a 3x Wild participates from each reel. Several Wild positions can also exist on the same reel, but the multiplier assigned to Wilds on that reel is shared. The important factor for each winning line is which multiplier Wild reels actually form part of that particular combination. The Paw Print Bonus symbol is restricted to reels one, three and five. Landing one on each of those reels during the same spin pays 5x the total bet and activates Free Spins. The number of Free Spins is not fixed. Before the feature begins, a separate three by three grid appears and each of its nine positions reveals either 1, 2 or 3 spins. All nine values on that grid are added together to determine the final bonus length. Since every position contributes at least 1 and at most 3, the Free Spins round can begin with anywhere from 9 to 27 spins. The result of this opening draw is particularly important because a longer bonus gives sticky multiplier Wilds considerably more time to accumulate across the central reels. Every kennel Wild that lands during Free Spins becomes sticky. It remains fixed in exactly the same position for every remaining spin and retains the multiplier assigned when it landed. A 3x Wild arriving early in the bonus can therefore continue contributing its multiplier to qualifying line wins for the rest of the feature rather than disappearing before the next spin. Sticky Wilds can accumulate on reels two, three and four as the bonus develops. When several of them contribute to the same payline, their multipliers continue to use the additive rule from the base game. This creates the main progression in The Dog House, since the reels can gradually become increasingly occupied by permanent Wild positions without requiring a separate multiplier meter. The Free Spins feature cannot be retriggered. Bonus symbols are absent from the special bonus reels, so the number generated by the opening three by three grid represents the complete number of spins available. The original The Dog House also has no conventional Bonus Buy, respin feature or progressive jackpot. Its entire high value structure is concentrated around multiplier Wilds and their sticky transformation during Free Spins. The Dog House succeeds because its bonus builds visually and mechanically from one spin to the next. A short feature may finish before many useful Wild positions develop, while a longer round can give early 2x and 3x Wilds repeated opportunities to contribute across the 20 paylines. The strongest situations come when several sticky Wilds occupy useful positions across all three central reels, allowing their additive multipliers to repeatedly enhance combinations during the remaining spins.
