Summary: Jigsaw 365's hook is the fact that it uses a calendar as an interface for its 365 base-level jigsaw puzzles of cute animals, plants, and other appropriately inoffensive scenery. A puzzle a day, get it? Unfortunately, that's just about all it has going for it.
Pros: 365 default puzzles, Ability to add your own images, Decent interface
Cons: Max number of pieces is 200, Nonstandard piece designs are just dumb, You can probably get something just as good as this for exactly free
