The Dog House - Muttley Crew Slot by Pragmatic Play

Wins form through clusters of 5 or more matching symbols connected horizontally or vertically on the 5x5 grid. Six tiers of cluster size determine the payout: 5-6 symbols at the base level, scaling up through 7-8, 9-11, 12-14, 15-19, and 20-25 for the top reward. Only the largest cluster per symbol type counts.

Every Wild lands carrying a random multiplier - 2x, 3x, 5x, or 10x. When a Wild sits inside a winning cluster, that multiplier applies to the entire payout. Two or more Wilds touching the same cluster add their multipliers together rather than multiplying, so a 3x and a 5x in one cluster give 8x total. A single Wild belonging to multiple adjacent clusters applies its multiplier to each one separately.

Three, four, or five Bonus symbols start 10, 15, or 20 free spins. The key shift: every Wild that appears stays locked in place for the rest of the round. As spins progress, the grid fills with sticky Wilds and their stacked multipliers. Bonus symbols land as overlays during free spins, with 2, 3, 4, or 5 overlays awarding 5, 10, 20, or 30 extra spins. Buy options at 100x, 250x, and 500x guarantee 3, 4, or 5 Bonus symbols respectively.

Up to four progressive jackpots (MINOR, MAJOR, MEGA, GRAND) trigger randomly after any base game spin. A pick-and-reveal screen appears where matching three identical jackpot names reveals the prize. Higher bets increase the trigger chance, though any bet above the minimum qualifies.
