Thanks. I think that makes it much more suitable for my kid. I like that the page is simple and clean without ads/garbage. Depending what your goals are you could call it done. Here are some more thoughts if you keep tinkering. - Always produce a puzzle. If the request is for a small grid and a large number of words and it doesn't work, decrease the number of words and output that. The total number of words is not that important. - Instead of a download image, update the displayed puzzle with the new image and add a download button. The image is no longer a preview, just call it the puzzle. Perhaps add a transition/something to highlight the update. - Add a download PDF button. Dumping the image into a PDF with PDFsharp/whatever should be pretty easy. PDF children's activities sheet keywords etc are presumably helpful. - Add a bit of padding between the letters and the boarder. - Add a link/qr code to the image/background/metadata to give yourself some credit.
