Absolutely the worst app. I kind of figured it would be but I have came across a couple apps that pay like they offer.... THIS HOWEVER IS NOT ONE OF THOSE APPS!!! Started grinding and decided to go after the 300.00 in green coins, everything was going swimmingly until I hit about 290.00 and that's when all the green coins were reduced to 0.0001... Undeterred, I continued up to about 293.00 and that's when the green coins stopped completely. Even the slot machine stopped recognizing the green.
