The Dog House - No Dog Left Behind Slot by Pragmatic Play

Seventh game in the Dog House series, built as a Stake Casino exclusive. The underlying mechanics are identical to Dog or Alive - same grid, same features, same 10,000x ceiling. What this version adds is a layer of progressive jackpots that the standard release doesn't have, plus a different distribution model aimed at a single operator's audience.

The 100x buy bonus drops you straight into a 3x3 picker where each cell shows 1, 2, or 3 free spins. All nine cells add up for your total - minimum 9, maximum 27. No choice involved, just a roll. Waiting for a natural trigger needs three bone scatters across reels 1, 3, and 5. Once inside, every wild that lands on reels 2, 3, or 4 sticks for the duration and keeps its random x2 or x3 multiplier visible. Two wilds sharing a payline add their multipliers together, so x3 plus x3 pays at x6.

The escalation kicks in at collection milestones. Accumulate 3 sticky wilds total and every multiplier on screen doubles - that x3 is now x6. Hit 6 wilds, they double again to x12. Fill all 9 possible positions (three rows across reels 2-4) and a third doubling pushes a starting x3 up to x24. Two x24 wilds on the same payline combine to x48. Each threshold also adds 3 extra spins, so wild accumulation and retriggers feed each other. Getting past 6 in a single round is uncommon. Reaching 9 is where the max win math lives.

Four progressive jackpots - Grand, Mega, Major, Minor - trigger randomly after base game spins only, never during free spins. A pick-and-match screen reveals the tier: find three matching symbols and that pot pays out. Higher bets push the trigger odds up, and there's a minimum bet floor for eligibility. Dog characters in cowboy gear fill the premium pays, a golden sheriff badge is the wild, and the whole thing plays across 20 fixed paylines with bone scatters limited to the odd reels.
