Description by FTY LLC. (from Google Play)

Spot suspicious tenants. You are the landlord of an apartment.

In this apartment,
not only good people but also criminals and even monsters are mixed in.

Investigate each applicant’s background
and decide whether to let them move in.

Fill your building with good tenants
and create the best apartment possible.

■ How to Play
Check each applicant’s criteria
and determine whether they are good or bad.

More “Yes” → Higher chance they are a good person
More “No” → Possible criminal or monster

If you accidentally let in a dangerous tenant,
trouble may occur in your apartment.

■ Apartment Reviews
Let good tenants move in to
increase your apartment’s rating.

The higher the rating,
the more rent income you earn.

■ Monster Attacks

invade your apartment.

When that happens, fight them off with a gun.

You can restock ammo and upgrade your weapons
at the gun shop.

■ Game Features
・A deduction game where you identify suspicious tenants
・Story-driven interactions with visitors
・Test your judgment in spotting good vs. bad people
・Increase ratings to boost rental income
