Idle Prison Tycoon

Idle Prison Tycoon is a portrait-oriented idle tycoon game where players build and manage their own prison. The core mechanic involves tapping to generate income and upgrading facilities to expand the prison. Its appeal lies in its simple, repetitive progression and one-handed playability, suitable for players who enjoy passive growth and don't mind frequent ad interruptions.
