Play the free money as long as possible, delete when you run out and move to the next one. I honestly got 10 times the starting money before I even began watching videos. So even if I would go broke you could easily get enough play money to last you a very long time in a very short time. Now most slot apps tend to do this, hit hard and fast and then burn you dry. This may be the case here, and it probably is who knows. Highly recommended.
