I time my free play wins carefully. The scarf event for instance. If I am busy, I hold off on a reward level until I have time to work those free hours. I am not fan of the cat event. It's still too hard, though better than it was at its inception. I have been able to progress in the game recently without paying through the nose by scheduling those unlimited lives. Am on level 1033. It's a beautiful game but tough. I really think we need a better event than the cat mahoosie to gain more coins.
