As Dan seems to have gone into the background in publishing daily puzzles, perhaps it's time to thank him for his efforts over the years.
AFAIK he published a puzzle on October 21 2012, which you can see here and subsequently published one every day until recently.
This series and the patterns game have kept the forum active over the last 5 years, as new solving methods have dried up and, I strongly suspect, will never be found. If they were there to be found, they would have been found by now.
Anyway, thanks Dan for a fantastic effort over the last 5 years.
