App good but. Every machine we play is just keep eating our coins. We buy coins so much and we don't get any free games. If we do get free games 500 bet we get only 300 to 1000... the dragon are useless too. Is suppose to be fun games but not anymore. Most of my groups left. My opinion don't buy coins anymore your wasting your money... I get over it.. I'd been this games for 7 years and is getting worse everyday..
