    I enjoyed the flow of this one, and it fell into place quickly once I realized where to start (which took me a little longer than it should have). Fun puzzle, and I’m glad to see the guest constructors getting a chance to play with their own favorite puzzle types.

    1:35, and it took 20 seconds to write the answer key. Oh great. NEed to be faster at writing answer keys.

    Grant’s typical theme of being pretty easy all over, but with exactly as much clues as needed. The next step is always in clear view; you only need to find the correct given. Perhaps I’m already familiar with Grant’s Cross The Streams. But a good, clean puzzle.

    I hadn’t seen this puzzle type before and I love it, since it involves elements of several of my favorites. I worried that I would mix up the * and ? symbols, but that hasn’t happened so far. Off to try today’s installment!

      The wildcard symbols ? and * are familiar to computer programmers; commonly, ? represents a single character, and * represents any string of characters. So *s? can represent cross, but not streams. *s* can represent cross or streams. Hopefully that helps a little, somehow. 🙂

    Wasn’t that hard, but I really liked the flow of it. I suppose I do like these puzzles after all 😀 (in reference to my comment on the pi-themed Cross the Streams)

    5:12 A nice introduction to the genre.
