Unfortunately, Plarium Play currently doesn't work with Apple M1, Archon 😢. In that case, I would recommend you try to install Rossetta and open the game through it. 

Nevertheless, we are planning to launch Apple M2 on Plarium Play in the nearest future! Twiddle thumbs 🙌

Thanks, Archon, for helping. As was mentioned, Plarium Play currently doesn't work with Apple M1, unforunately

Yes, it's possible that the game requires Adobe Flash to run, and since Adobe Flash is no longer supported on Macs, it may not be able to run on your MacBook Pro M1. You can try using a web browser that supports Flash, such as Google Chrome, to see if that helps. However, keep in mind that even with a supported browser, you may encounter issues or security risks when using Flash. Alternatively, you can look for alternative solutions, such as finding a version of the game that doesn't require Flash, or using virtualization software to run an older version of Mac OS that supports Flash.  

No browser supports flash player.

See if you can use Puffin, it's the only "browser" that still runs the game without the APP.
