Step into a post-apocalyptic world overrun by the undead and chase down massive wins in Rotten, a thrillingly dark zombie-themed slot that delivers relentless action across every spin.
Rotten unfolds across a sprawling 6x5 grid featuring 35 paylines, where winning combinations are formed by landing 3 to 6 matching symbols from left to right across the reels. Lower-value symbols are represented by the classic 10-through-Ace royal cards, while the real payouts come from the grotesque zombie character symbols that dominate the high-paying tier.
The game's wild symbol takes the form of a stretching, decaying hand, capable of appearing on all reels. This wild substitutes for every other symbol on the grid, boosting your chances of completing winning lines. Land six wilds simultaneously and you'll pocket an impressive payout of 50x your bet.
Beyond the base game, Rotten is packed with engaging bonus mechanics, including multiple free spins rounds and lucrative feature triggers that keep every spin unpredictable and rewarding.
The zombie characters sit at the very top of the Rotten paytable, delivering the game's most powerful payouts. The Clown Zombie is the premium symbol, while lower-tier royals fill out the supporting cast. Study the full paytable breakdown in the table below to understand exactly what each symbol combination is worth per spin:
Trigger the Switch Spins feature by landing the switch symbol anywhere on the 6x5 grid. Once activated, this mechanic rewards you with between one and ten respins.
Before the respins kick off, selected symbols on the reels are swapped out and replaced with either higher-paying zombie symbols or wilds, dramatically increasing your win potential. Each transformed symbol is clearly displayed above the game board and remains locked in position for the entire duration of the feature, ensuring every respin carries maximum weight.
Collect three Mad Scientist symbols anywhere in view during the base game to unlock the Mad Scientist free spins round, which awards 10 free spins to play out on the reels.
During this bonus round, the frequency of switch symbols landing is significantly higher than in the base game, giving players far more opportunities to trigger symbol upgrades and stack up bigger wins across each free spin.
The most powerful bonus in Rotten is the Total Takeover feature, triggered by landing three Total Takeover symbols anywhere on the grid, whether during the base game or within the Mad Scientist free spins round.
This feature awards 10 Total Takeover free spins, during which switch symbols land even more frequently than in the Mad Scientist round. With enough switch activity, players can collect every symbol on the board, ultimately filling the entire screen with top-paying symbols or wilds for truly devastating results.
Land 3 additional Total Takeover symbols during the feature and you'll be rewarded with 4 extra spins, extending your winning opportunity even further.
For players who prefer to fast-track the action rather than wait for bonus triggers in the base game, Rotten offers a Buy Bonus mechanic with several purchase options:
