It is designed to take your coins so you'll have to spend $$$ update - Thanks for your reply. It amazing to Me how every time I win and build a nice amount of chips and as soon as I up bet I stop winning. This is not random in my opinion. It is fun to play the game but very frustrating. Update - Have a great day as well! Update - after playing hours I couldn't win anymore and lost every chip. Got great offers to spend money and ended up uninstalling the app.
