Password Lock is not your typical game. With a simple operation, you can find a surprise treasure, get an unexpected surprise picture, and have a key to unlock the password!

The goal is to get all the keys so you can open the password lock, which will reveal the surprise treasure. To get the keys, you need to keep on clicking on the password lock, and you will get them one by one. Once done, you can open the password lock by using the keys you got.

The game is a simulation, so you can enjoy it as if you are playing a game. You can play it at any time and place.
