Nothing special on your site, UI looks so bad on mobile. If you really wish to attract players so you need to work so hard to improve your site. Otherwise it will be just an app without any players and may dead soon.
Totally agree with Bitinity in terms of UI. Actually, as of now, users won't be able to play with convenience and see some options like "how to play" when using mobile. This can be improved though, and imo being responsive is one of the edge you may have compared to other moneypot apps. I used to try sites on mobile that's why it's a ++ for me if it's mobile friendly.
I saw your site is good enough to bet smaller, but I do not have moneypot and will not use it, it might be more interesting if all the users can also make deposits from their bitcoin wallet to your site, your site is already quite friendly to it
Op can work on adding a deposit address for users to add funds directly from their bitcoin wallet. It's possible since some apps already have that, but, you'll still need to have a moneypot account to be able to play.
