Can I Play WPT Global in the UK?

Can I Play WPT Global in the UK? Unfortunately, if you are in the United Kingdom, you cannot play on WPT Global. The platform does not offer its services in the UK, as well as in other regulated markets such as Southern Europe, including France, Spain, Italy, and Portugal. However, you might consider downloading the online poker app from the App Store to see if it works for you. Please proceed with caution, as access may still be restricted.
