Prison Pump

Prison Pump is a gym-clicker and incremental strength simulator by The Gang Stockholm set inside a hostile penitentiary where players start at the bottom of the prison hierarchy and grind their way to dominance. Released in September 2024, it has surpassed 143 million visits and 2.96 million favorites with a 96% approval rating - one of the fastest-growing simulator releases on the platform.

The core loop runs on a tight cycle of reps, recovery, and yard fights:

• ⚔️ Challenge NPC gang members in the yard through a bar-filling combat minigame to earn Cash
• 💼 Rapidly tap to perform workout reps until stamina depletes, then recover and repeat to raise Strength
• 🏆 Prestige up to 40 times to reset base Strength in exchange for permanent multipliers and exclusive content
• 💰 Cash from yard fights buys Canteen upgrades for passive Strength gain and Commissary items
• 💎 Crystal Shards serve as a secondary currency tied to prestige-level content and rare purchases
• 💼 Auto Workout Boosters eliminate manual clicking entirely - unlocking them transforms the grind into a fully passive loop

Strength tracks per muscle group across chest, back, arms, and legs, with overall Power calculated as the average across all four. Balanced training across every group is required to maximize Power. The 40-level Prestige system - added in the Maximum Gains update - gives long-term players dramatically accelerating runs through compounding multipliers.

Prison Pump's community engagement is one of its defining features. The developer posts the exact next Like-milestone threshold in the game description, giving players a predictable target and turning the Like count into a shared community goal.
