# Overview

You can visit the Modify Room in case you wish to modify or correct an already existing puzzle. To reach the Modify Room:

1. In the Store Room, click the right mouse button on a puzzle you would like to modify.
2. Choose Modify in the displayed context menu.

Fortunately, you do not have to learn how to work with another room because the Modify Room and the Create Room are almost the same.

- If you modify a puzzle, it will be automatically decomposed.
- If you are in the Modify Room and would like to get back to the original version, just click Back in the room main menu and do not confirm changes.
- Being a surprise puzzle cannot be modified.
