Idle Customs: Protect Airport is an idle game that combines the fun of a simulator game with the management of an airport. You’ll play as the new Head of Customs, right? We’ve been waiting for you! Pretty cool, isn’t it? It’s a bit crowded, but we’re sure you’ll be able to sort it out! Just be careful! Lots of people try to smuggle illegal goods into the country through here. It’s up to you to keep this airport safe!

How to play

As the new Head of Customs, you’ll manage the screening process for all incoming passengers. You can split it up into three parts: visa check, passport control, and security check. Passengers pay a fee to enter the country and, if they get caught trying to smuggle goods, they pay a fine. You’ll also earn money whenever a passenger successfully enters the country or when you find illegal goods in their luggage.
