From what I can tell you need to be lucky. When I register my (European) account there are ARM resources left and they were easy to claim. I think I was lucky because they just expanded a data center somewhere nearby, though, I think there was info about it on a Reddit post somewhere.

I don't think the forever-free tier allows cross region instances. You may just need to register an account in another region where they have more resources, but it's anyone's guess where Oracle still has them.

It's a neat playground but as should be blatantly obvious it's not worth investing too much time into, because they can make it disappear without recourse for no reason without warning.
