Best way to incorporate play for fun slots in a page?

[CatalinAMG]

I've tried with iframe but the page freezes, especially when testing on mobile. Although the scrolling was enabled, it was impossible to scroll past the iframe. Also, does someone know how to add a cover for these boxes so that the iframe/responsive box doesn't load until the visitor presses a button like "try now"? Hope I was clear enough. Thank you
