David Millar, of the excellent puzzle site The Griddle, has launched a new collaborative puzzle site called Perplexible. The intent is to provide a forum for diverse puzzle authors to post new creations. I’ve posted an unusual Slitherlink there, and hope to post more unique puzzles, in the future.
I occasionally get emails from puzzle constructors, who want me to publish their new puzzles. If you are one of those people, consider posting it on Perplexible.
