Frustrating, addicting, fun but overall feels rigged. Buy something they take away options to watch videos for help. Cards repeat numbers and suits excessively, it is not a set deck. The cost of story progress is insane. The translation is pretty rough. Also you may get glitched out of 50k prize like I did. Great idea, game play is easy and fun enough to grind but at some point it just gets tiresome. Also waaaaaaay too many ads.
