Total waste of time. First day I was able to cash out a little over $3. Today I had about $1.68 & the app disappeared, not the games just the app. When I reinstalled the app my cash was gone but I had an abundance of coins. When my 3 hours was up I had over 800k coins but they only converted to $0.63. There's no rhyme or reason to the conversion rate or the rate of coins you get.
