Hashtag (#) was sent to me by frank and I found it very interesting for a couple reasons. First, the level 25 solution is startlingly high given the low number of pieces. Second, I hadn't made a board burr in a while and this one was very unique in appearance. Third, I wanted to be able to write a puzzle description that included this: #winning!
Construction of this puzzle is excellent, with bevels and shoulders to suit. Fit is good, very slightly loose to ensure proper function.
