How do you add levels to your game?

Hi! I’m making a simple puzzle game with 50 levels, but I have no idea how to add levels to my game! If someone could please tell me or leave a tutorial link that would be great! Thanks!

Level is also called scene in Unity. Refer to below how to create scene:

To add the levels created to game, you can go to build options and tick those level you created.
