Tried loading up the game for the first time and it looks like some sprites are missing. Whats the issue & fix here?

Yeah I noticed that too when I first played. Maybe it's because of the end of life shutdown on Adobe Flash on browsers? Since you need Adobe Flash enabled to play CoolMathGames. I don't know. That's what I assume.

I never ran into this issue but you can try:

1. clicking the lock at the top left, next to the url
2. clicking the dropdown menu next to 'flash'
3. changing it to 'allow'

Update for anyone else who has this issue: I was not able to fix this issue on Chrome, so I switched to Microsoft Edge and it was fine.

It's fine on Microsoft Edge. Not working for chrome, same issue. Disabling adblockers helped once, but returned to this screen after 3-4s.
