The Dog House Multihold slot

The Dog House Multihold is a 20-payline, 5x3 slot where the money is in the wilds. They only appear on reels 2, 3 and 4, and every one carries a 2x or 3x multiplier. When two wilds sit in the same winning line their values add together, so a 3x and a 2x turn a R10 line win into R50. The base game pays often, about one spin in four, but most of those wins are small, and the 9,000x top prize sits a long way out at roughly one in five million spins.

The free spins are what set this version apart from the original Dog House and the Megaways one. Three paw scatters on reels 1, 3 and 5 give you 7 spins on a single grid. Any wild that lands during the round becomes sticky and stays in place. Collect three more bonus symbols and a second grid unlocks next to the first, you get 1 to 3 extra spins, and every sticky wild on the first grid is copied onto the new one.

That copying rule is the whole point. Up to four grids can open, and each one starts with every sticky wild the previous grid had collected, then adds its own. All four grids spin together on the one stake, so a R2 spin is still R2 even when four boards are paying. The best rounds end with multiplier wilds stacked across four grids and every line win counted four times over. The worst rounds stay on one grid and finish in seven spins.

Scorebet carries the game in its Pragmatic Play lobby, and a bonus buy at 100x the stake is offered where the regulator allows it, which goes straight into the single-grid start of the feature. The buy does not help you unlock the other grids, that still needs scatters. The RTP of 96.06% is the standard setting and operators can run it lower, so check the paytable inside the game before you stake.
