Every puddle is unique but all have a few common characteristics that make them most suitable subject matter for a series of jigsaw puzzles, to be known as Jigsaw Puddles of course.

All puddles have irregular edges, meaning that the jigsaw becomes impossible to start by finding all the corners and straight edges, as there are none. This means that Jigsaw Puddles are quite challenging to solve.

All puddles are of a fairly uniform colour, especially if they are photographed reflecting a clear blue sky etc. This adds to the degree of difficulty, depending on how much the puddle pic is devoid of features, like reflected trees or passing birds.

Once complete, you can leave your Jigsaw Puddle on a table top to act as a large coaster.

Problem is, if you place two puddles side by side and touching, they flow together and become one puddle even if the edges are not a perfect match. This could be like those people who do jigsaw puzzles by hammering down on ill-fitting pieces to make them lie flush on the table.
