About the Game

Scam Centre Simulator: Under Kingdom is a darkly humorous management simulation game.
Burdened with massive debt, you are invited to a mysterious town to build your own underground scam empire. Manage your scam compound, abduct tourists for labor, gather essential resources like electricity and food, and trade with the mayor, police, and locals. Will you rise to rule the Under Kingdom, or be consumed by chaos?

Use a variety of scam tactics to generate profit, from theft, phishing emails, and manipulating dating apps, to running online casinos and even cheating at the gambling table. Upgrade your equipment and turn every deception into flowing profit.

Search for individuals with different specialties, cleaners, porters, dealers, and bring them under your control through force. Assign roles strategically, maximize their abilities, and build a highly efficient underground operation.

Manage your scam center and maintain order within the compound. Monitor your workers’ physical and mental condition, and maintain control through punishment or “re-education.”

Upgrade facilities, customize and decorate your base, and expand your criminal empire. Record and customize employee voice lines to enhance immersion and control.

Progress through the story to uncover the dark secrets buried beneath the town.
