I was dumb enough to spend over 100 bucks. They do not give any benefits for buying coins. At the very least I bet low and lost fast. There are no wins, and the bonus you get in a round you play as teams is basically nothing. Fun game, no ads and no wins. I could of had an extra 100 bucks for the upcoming weekend going to Boyd casino in Kansas City. Keep up the fun by letting paying customers win once in awhile.
