I downloaded this game to earn credits through another app but it turned out to be one of the best casino type apps I've tried in a while. It doesn't have a lot of ads and the coins they give you actually aren't gone after playing one game. They have extra things you can do daily to get more coins & it gives you extra coins every time you level up. I'd recommend this app over almost all the others like it, if you're looking for something fun to kill time this is it.
