Rumble Mutts

Max Win Gaming sets Rumble Mutts in a graffiti-lit alley, giving it a punk-inspired neon look with a reddish tint over the city backdrop. Five reels and three rows carry 20 fixed paylines, with stakes running from 0.20 to 20 per spin. The maths sit on the high-volatility end, returning 96.31% overall with a 21.78% hit frequency, and the top prize reaches 25,000x the stake.

Five dog characters serve as the high-value symbols, worth 5x to 15x the stake for five in a row, while bottle caps, drink cans, animal traps and flaming eight-balls fill out the lower-paying end of the table at 1x to 1.5x for the same length of win.

The wild substitutes for every paying symbol and expands to fill its entire reel whenever it lands, revealing a multiplier of x2, x3, x4, x5 or x10 that applies to any win it forms part of; when more than one expanded wild contributes to the same win, their multipliers combine additively. A five-symbol wild line alone pays 15x the stake.

Landing two scatters together with a dedicated free spins symbol triggers 15 free spins, during which expanding wilds stay locked in place rather than resetting each round. A separate Junkyard Bonus opens when two scatters land alongside a Junkyard symbol: each reel is given a random value drawn from 200x, 500x, 1,000x, 2,000x or 5,000x, and the round begins with three respins that reset whenever a new symbol appears. Four special symbols can interrupt those values as they land — one subtracts an amount from its reel's total, one wipes a reel's value to zero and shuts it down, one restores a reel to its starting figure, and one locks a reel's current value in place until the round ends. Once three respins pass without a new symbol landing, whatever values remain standing are paid out.

Both bonus rounds can be bought directly: the free spins for 80x the stake, or the Junkyard Bonus for 500x.
