There are a few ways to obtain chips without spending any money in the game. There will be a button to collect bonus chips. Once those chips are claimed, you will have to wait before you are able to add more bonus chips. You can also acquire free chips by watching a video ad and by unlocking achievements. The last way to obtain chips is by sharing the app with friends. You are able to earn chips once per day for each type of sharing: texting, emails, and tweets. Of course, if you don't want to wait, you can always purchase more chips in our store at any time.
