Am I able to play Apple Arcade on the 6th gen iPad?

They don’t list device restrictions
What I am going to presume is as long as your device is compatible with the game then arcade should work.
They do have a free trial, so you could always try it, just be sure to cancel it within the first month or it will automatically renew each month thereafter
