How to edit my games in Google Slides
Good news! If you're using Google Slides, you don't need to request access in order to edit my games. Just copy the game to your own Google Drive (make sure you use a Gmail account).
For individual files
Go to the "File" menu, hover over "Make a copy," and select "Entire presentation."
For multiple files in a folder
Click the three dots and select "Make a copy".
