Do the time. Run the crime. Prison Struggle: Idle is a gritty crime idle-RPG set inside the walls. Start by combing the yard drains for loose change and claw your way up to blowing the main vault wide open. Every job you pull earns cash and XP — and the hustle keeps paying out even while you're locked away from your phone. EARN WHILE YOU'RE AWAY Your inmate keeps working when the app is closed. Come back to stacks of cash and a pile of loot from the jobs that ran while you were gone. Tap in, collect, and push for the next big score. CLIMB THE CRIMINAL LADDER Eleven escalating jobs, from petty pickpocketing and shakedowns to armed robbery, breakout runs, and full-blown vault demolition. Bigger scores demand more nerve, the right gear, and a body built for the work. SPECIALIZE YOUR BUILD Unlock four skill branches — Muscle, Hustle, Stealth, and Influence — and spend skill points on permanent upgrades that stick with you. Boost raw power, juice crime payouts, sharpen drop rates, or stack bonuses for raids, fights, and territory wars. Respec when your hustle changes direction. GEAR UP Loot shivs, brass knuckles, pistols, riot shields, kevlar, gold chains, and legendary blades from your crimes and boss fights. Equip the best with one tap, sell the rest, and tune your build around four stats — Attack, Defense, Speed, and Stealth. THE WORKSHOP Salvage duplicate gear into materials and craft contraband in your own queue — lockpicks, guard uniforms, burner phones, and more. The best inmates don't just loot the yard; they manufacture what the block can't buy. RECRUIT CELLMATES Build a crew of idle earners tied to your crimes. Each cellmate stashes cash passively while you run the yard. Upgrade them, collect their haul, and watch your idle income compound. DAILY CONTRACTS Fresh bounties every day — hit crime targets, win fights, deal raid damage, craft gear, upgrade cellmates, and more. Chain completions for streak rewards and bonus cash. PIMP YOUR CELL Spend your earnings on permanent upgrades: a weight bench for raw power, a smuggled treadmill for speed, a false wall panel to stay unseen, black-market rations to soak up punishment. A fully kitted cell is the difference between a small-time crook and the inmate who runs the block. ENDLESS RAID — TOGETHER The whole block fights one shared boss at a time. Every kill spawns a stronger successor — climb stages together before the 4-hour window runs out. Chip HP in real time, share the loot with everyone who contributed, and push for the highest stage score before the run ends. Raids spend Energy, separate from Nerve, so auto-running crimes never drains your fight bar dry. 1v1 FIGHTS Challenge NPCs and real players head-to-head for cash, XP, and loot when you've got the muscle to back it up. JOIN A CREW. CLAIM THE YARD. Form or join a gang, climb the leaderboards, search for rivals by name, and fight for control of the prison map. Conquer territory tile by tile across a living seasonal map — every tile your crew holds buffs every member. Launch war strikes against rival gangs and grind your way to the top before the 14-day season resets. FAIR PLAY, BUILT IN Every payout, drop, and boss hit is verified on the server, so leaderboards and territory wars are won by the smartest hustle — not by cheaters. Gritty. Tense. Always grinding. Build your rep, gear up, gang up, and take over the block. Crime never sleeps. Will you?

The line fights on its own. You decide what gets stronger. IRONVOID is an idle RPG that plays out on a strip at the bottom of your screen. Your squad holds the right, enemies come from the left, and the shooting is automatic. You don't aim — you build. BUILD THE SQUAD Five distinct units, a party of three. Each has its own skill tree, its own gear, its own job. Marksman, guardian, medic — the formation is yours. LOOT, MERGE, UPGRADE Every drop is a decision. Fuse nine same-tier pieces in the Cube to force one tier up. Thousands of gear identities: no two pieces of the same tier are alike. STONES AND SOCKETS High-tier gear takes stones. The same stone behaves DIFFERENTLY in a weapon, in armor, and in support — where you set it is permanent. PROGRESS OFFLINE The line keeps fighting while the game is closed. Your patrol report is waiting when you return. AN HONEST ECONOMY No gacha. No paywall. Nothing you buy raises the power ceiling — every stage is beatable for free. The only thing sold is time and convenience.
