The coin system is quite screwed on wins and losses especially in the lowest setting. Also buying a 500 coin item took 5,000 away instead of said 500. Another game I earned 90 coin but next game i had a loss in the same game style and lost 700 coin. Unreliable and quite irritating. Tried uninstalling and reinstalling it and all but nope still screwed. Again not sure what that's about but it has made the game unenjoyable. Even tried to just bare through it.
