I do a lot of on screen jigsaw puzzles, they can be uploaded as .exe files if you don't have the software, one forum I'm on has a weekly one but some virus checkers take ages to allow running it. For those with the software a completed puzzle can be saved with a file extension of .pzp which can be uploaded or emailed as an attachment, others can then download and open in their own puzzle software. The software allows any image to be made into a puzzle, number (and shape) of pieces can be set from about 18 to 1200, size of screen and one's eyesight will have some bearing one what one chooses. "Doing" a puzzle involves picking up a piece with the mouse and placing it in the jigsaw, if you get it inthe right place it locks in place with a click and a momentary star alongside Software is not free, cheapest version (entry) is $9.99, the only difference between that and the dearer ones is the number of sample puzzles included. https://www.tibosoftware.com/ Certainly a way to pass the time while in lock down, have fun.
