Gaming on mobile is a convenient option but cannot be the ideal choice for many people.
For people who don't have a desktop/laptop it can be the best option though but most people who has a desktop/laptop don't prefer gambling on mobile phone.
Gambling on desktop provides the best user experience.
I have both Desktop, Laptop and Mobile devices but I prefer gamble on my mobile device due to convenience it can offer. You don’t need desktop power in online gambling since most of the games is easy to load which gives same user experience for both mobile phone or desktop.
I only use my desktop whenever I play games that has a high resolution since mobile phone can’t handle that kind of processing power and render but in terms of gambling games. I always preferred mobile over desktop because I can gamble comfortably while lying on my bed.
So it really depends on the individual's choice. Even I have a desktop, laptop as well as mobile yet I prefer gambling on desktop and laptop.
To me it's the bigger screen that provides an exotic user experience while gambling. Mobile screens are relatively smaller and hence the experience is not truly amazing to me.
