Raging Rabbit
A furious boxing rabbit in a gritty 1940s back-alley gym. A 6×5 pay-anywhere grid with tumbles, Punch Marks that flip into coins and multipliers when a Golden Carrot lands, and a bonus ladder that climbs to a guaranteed 2,000x.

How it plays
Eight or more, anywhere
Land 8 or more matching symbols anywhere on the 6×5 grid to win. Winners explode, new symbols drop into the gaps and the tumble keeps going for as long as new wins keep landing.
Every win leaves a Punch Mark on the board. Marks are quiet until a Golden Carrot drops — then every mark on the board flips at once.












Signature mechanic
Punch Marks & the Golden Carrot
When a Golden Carrot lands, every Punch Mark on the board flips into one of these.

Coins
Copper, silver or gold — each mark becomes a coin worth a multiple of the bet.

Haymaker
Multiplies the whole spin win.

Uppercut
Multiplies the coins next to it.

Collector
Collects the value of every coin on the board.

Combo multiplier
Bonus only: stacks multipliers through the feature.

Death tile
Rare. A coin flip: a KO multiplier, or nothing at all.
Four carrot rarities
Rarer carrots, stronger flips. Golden, Ruby, Diamond and Champion.
