Let Them In is an engaging deduction game available on iPhone that challenges players to act as landlords in a mixed-tenant apartment building.

With its unique blend of deduction and action gameplay, Let Them In offers a captivating experience for those looking to test their landlord skills in a quirky, entertaining setting.
