About this Slot
Sewer Shellbacks is an action and adventure crime-themed slot from Nocap Labs with a 96% RTP, high volatility and a maximum win of 20,000x. The game uses a 5-reel, 6-row layout with Cluster Pays mechanics.
Wins trigger a charge meter that builds towards blast effects and multiplier increases. Cell multipliers grow through Pizza Multi, doubling up to a maximum of x4096. When the meter fills completely, Sewer Blast activates and ends the spin at the 20,000x maximum win cap.
Landing three Bonus symbols awards 8 free spins. Four or more Bonus symbols trigger the Super Bonus, which grants 7 free spins instead.
A Mystery feature triggers randomly during play, awarding either a bonus outcome or a hidden bonus. Cascading reels continue the action by dropping winning clusters away and allowing new symbols to fall into their place.
Nocap Booster provides paid entry options with varied starting conditions, allowing players to buy direct access to bonus rounds at different price points.
