Most gamblers end up gambling on their mobiles way more often than their desktops which makes sense due to reasons like portability, higher usage etc. I tend to have more fun gambling on mobiles too.
I said that for me gambling upon desktop is best rather then on mobile devices because I have more better experience on wide screen and access all the features.But yes there are many gamblers who wager on the mobile device as all don't have desktop device with them so it depends on our personal preferences.
