Telehealth Resouces - Older kids/teens

I was hoping to find some online resources for games to play in telehealth sessions with older kids and teens. I recently moved to strictly telehealth platform and many of my face-to-face clients were willing to swap to that format.

Quick google searches show some resources but they require the client to download things, or don't work quite well on phones/tablets.

I know of a few such as chess.com and some IO games but wanted to see if anyone else had any good resources to check out.

I apologize in advance for any issues of this post, its my first time posting here, and thank you in advance!
