Description
Solve mysterious cases, build and run your prison, keep inmates in line, halt riots, and climb the ranks in this ancient idle tycoon adventure!
Prison Idle Bao, made by Ins alongside their many other idle games, puts you in the role of Master Bao, who oversees the justice system and a prison. Set in an ancient civilization full of strange cases and unruly criminals, the game lets you grow your courtroom and prison facilities while making key decisions that earn prestige and push you toward greater power.
Judge Cases and Uncover the Truth
Your job is to sift through the evidence and form your own verdict on each case, which determines the outcome and earns you prestige. Sound judgment and good results bring you up through the ranks of power, and many cases will require careful thinking to get at the truth.
Build and Expand Your Own Prison
Construct and manage facilities for both inmates and staff, improving conditions for everyone. Upgrade your facilities to help your staff and keep your prison running more smoothly.
Manage Your Inmates
Every day you'll run your prison and look after your inmates, watching their needs and applying the right methods of control whenever trouble breaks out. Sound management decisions are essential to keeping order and stability in your prison.
Control Riots and Emergencies
Minor discipline problems can quickly escalate into serious prison disturbances. Be ready to put down riots fast to restore order while you keep building and improving your prison.
Upgrade and Grow
Make smart choices to expand and improve your prison, and use your resources wisely. The better your facilities and the more efficient your operations, the more inmates you can house and the bigger the challenges you can take on.
Rise Through the Officer Ranks
Opportunities extend beyond the prisons you manage. Through a series of well-made decisions and effective governance, you'll build your prestige and the court's favor, letting you climb the ranks of the judiciary and advance through the official hierarchy.
