After several weeks of work, I have finally got my puzzle drafting tool to a state that is ready for release. The current version of the tool can be found under the Puzzle Maker page of this blog. As of now it supports puzzle drafting for 7 puzzle types, and solution checking for 3. I will be continually adding more puzzle types and features as time permits.
If you have any bugs, comments, or feature requests, please leave a comment on the blog and I will respond as soon as I can.
P.S. I am also going to be updating my old posts to contain the new pictures from this version of Puzzle Maker, as well as links to solutions.
