This is with Chrome browser on Android. This occurs the same under both a mobile device as well as with a tablet (Nexus 7)
Right now the site is a black hole when using my Android mobile (with Chrome). The press on the spin button does do a spin and then the spin button reappears. But the second press causes the button to disappear but no spin occurs. There is no recovery as far as I could tell. This occurs when playing for free as well as if I've signed in and have placed an actual wager (and thus the black hole, you will lose your wager). Something should be done to either disable the game when on a mobile or the game should function on a mobile as well.
My mobile (LG Optimus Elite) is running Android v2.3.7. Incidentally, this same behavior does not occur on a tablet (Nexus 7) running Android v4.2.
I'll put up a "doesn't work on mobile" redirect of some sort asap. I wanted to get a basic version out there to see what the response was (test the waters) before investing in other platforms. But yes, I should at least have a redirect. Sorry for the poor experience.
