It took much longer than exspected. When first started ad's we're minimal. As it progressed the ads seemed to take over. No only were they longer they intruded on the puzzle. Frequently I would have to reboot just to get back to the puzzle. Unless you want a challinge with the OS as well as the jig saw you might want to look elsewhere. My feeling is the company is doing a diservce to the person who did the puzzle. When I received a msg telling me I had to upgrade. I uninstalled.
