Thirteen Doors

Thirteen Doors is a short card-based mystery game. You wake inside a strange building with thirteen doors and no map, only cards. Choose rooms, inspect objects, meet a stranger, and combine items to learn what the building hides. Each run picks secret rules you never see. Watch what happens, make discoveries, and escape or disappear. Runs last about 5 to 10 minutes. Hidden rules change every run, and discoveries stay between runs. The mood is dark and gothic. The game is fully offline, with no ads, no accounts, and no real-money purchases. Some doors should remain closed.
