Update to my review. I play for free, and it's a really simple, but super fun addictive game. Earn your way, or pay. I earn. Those who play must spend THOUSANDS! bcuz the prices are exorbitant, esp as this is a simple thumb tapping app game. It's not bad working your way up, but ever since my last update, the game glitches out just about every 2-3 races, and also often when first loading up. Why the frustrating severity of glitching. Phone is new, and plenty of memory, strong fast internet. SOS
