It seems like you cannot acces and try the website without having an account created there. You should think about creating a demo version of your games where people can test it and see how it looks and how it works before actually playing with real money. And this demo should be available for everyone, without needing to create an account to try it.
Thank you for the feedback. This is something that was actually considered but didn't make it in before launching, we will look into it and possibly start implementing it over the following weeks.
