Hello,
We do not have pages of the Game demo on Elementor. But you can enable WPBakery, create a new page and import the desired page like shown here – https://youtu.be/wkIKN2IyEZI
Please do not edit pages using 2 editors, you need to be careful and edit a page using Elelentor or WPBalery only, depends on what editor was used to create the page, to prevent problems with the content displaying.
Regards
