There is a very old piece of abandonware called XFigure. It's described on the maker's website here: https://web.archive.org/web/19990421010752/http://homepages.tcp.co.uk/%7Esphipps/html/xfigure.htm. Here's the URL for the Internet Archive link to the zip file. It's 137 kB. I'm not turning this into a link because I'm not sure Internet Archive would see that as hot linking, and whether they think that's bad or not. (I may be overthinking this!) https://web.archive.org/web/20010615195759/http://homepages.tcp.co.uk/~sphipps/download/xfig160.zip
Here's an image of it running:
Getting it running is an un-fun experience. I installed D-Fend Reloaded. I then pirated and installed Windows 3.11 using these instructions: http://www.thealmightyguru.com/Wiki/index.php?title=DOSBox#Installing_from_multiple_floppies. Then I used created a folder in my dosbox virtual drive, and copied the files in xfig160.zip into that folder. The folder is available when I run dosbox and windows within dosbox. At the moment I run D-Fend, run Windows 3.11, then use file manager to run Xfig, but there's got to be an easier way and I'm looking at what that is.
EDIT: Turns out that there's a much easier way to run it! Install WineVDM, and then you can just double click the xfig file to run it in Windows 10.
So, it's a fun little game. It's pretty configurable. You get to have a customised rule set as well as pre-configured easy / cryptic options.
Here's the options page:
And here's an example of a cryptic xfigure puzzle
