Memory Game

How can I add different bits of functionality such as a shuffle button to the memory game?

Also is anyone aware of any games such as shoots and ladders that can be configured using these tools?

I am a new user and would like to know if I need to purchase an account to create different content? 

I am new to H5P and Wordpress in general and am trying to build an educational course suing Learndash, Elementor Pro, and some of the H5P activities and games.  I have created a pop up with a memory game inside of it but it does not show up.  The pop up box shows up after you click on the button, but there is a long thin white bar that shows up where the memory game is supposed to be.  Is this a problem with Wordpress or Elementor, or do I have the settings wrong with the memory game itself?
