Is it possible for me as a Czech to register in a Slovak casino?

I live in the Czech Republic. Can I open an account in a Slovak online casino (eg DOXXBet)?

And how is it vice versa? Can a Slovak register into a Czech online casino (for example, Sazka Hry Casino)?

Thank you for your response in advance.

You can always check the casino review on our website in order to see if the casino accept players from your country. This is Doxxbet:

Yeah, you can always check the review page. There's almost always a small text written there that says 'It accepts players from <your country depending on your VPN or no VPN>'. If it doesn't welcome Czech players whos trying to access a german casino site like slotsfreispele, you can find another online casino that does (based on their license). I would advise against using VPN because many casinos get in trouble for welcoming players from places they are not allowed to.
