I stopped playing this on my last phone, but I couldn't remember why..until now. You grind to get enough "coins" to get into a "course" with a 100,000 "coin" prize but have to pay 50,000 "coins" to even play it. I was super stoked when I won one of the 100,000 "coin" matches, just to have the damn app FREEZE AND RESTART ON ME!! Honestly, what the hell is the point in playing. It's happened about 50 times on the "earlier" courses, but I didn't mind that much because the fee was cheap. ZERO STARS!
