District 33 puts a crime-themed cast of rats, pigs and gangsters on a five-reel, four-row board. Its 20 paylines give the game a familiar structure, while expanding Rat Wilds and oversized Mushroom Wild blocks give the feature rounds a rougher edge.
Quick take: A 20-line crime caper where expanding Rat Wilds and moving Mushroom Wild blocks reshape the action.
Theme and Gameplay
Cheese, drinks, mushrooms and skulls fill out the rowdy underworld cast. On ordinary spins, watch for Rat Wilds connecting with a paying line: when they do, they can expand and carry a multiplier, making their position matter beyond simple substitution. Cheese symbols can upgrade Rat Wild multipliers, adding another reason to check what lands alongside them.
Slot Features
The free-spin modes change how the Wilds behave. Mad Rush and Shroom Ageddon use a moving 2×2 Mushroom Wild block; in Mad Rush, wins involving the block also build a multiplier. Freak Spins has Rat symbols spinning independently as Wilds. Super Freak Spins makes Rat Wilds sticky and expanding, while Freako Calypse removes J, Q, K and A symbols as sticky Rat Wilds remain. The modes give the game several distinct ways to turn the same board into a more feature-driven round.
Feature focus: Follow a Rat Wild that connects with a winning line, then check whether it expands and whether Cheese upgrades its multiplier.
RTP and Win Potential
District 33 lists 96.5% RTP, high volatility and a 20,000x maximum win. The high-volatility rating means results can be uneven, and the advertised ceiling is a theoretical top end rather than a typical outcome.
My Thoughts On This Slot
A winning Rat connection gives District 33 a satisfying focal point: the line matters both for its payout and for the expansion it can set up. Cheese upgrades add another detail to follow around that Wild. The moving Mushroom block offers a different attraction, especially in Mad Rush, where its wins also build the multiplier.
Remembering which mode keeps Rats sticky and which moves a block takes more attention than the familiar 20-line foundation suggests. That extra involvement should suit someone who enjoys tracking changing Wild positions through a feature. Anyone wanting a simpler rhythm may find the collection of modes, alongside high volatility, less inviting.
Final Take: District 33 earns its unruly character through Wilds that expand, move and change the next result's possibilities.
