When I <a href=\"https:\/\/puzzlezapper.com\/blog\/2024\/04\/edgematching-to-the-stars\/\">posted recently<\/a> about &#8220;starmaps&#8221; as a variation on edgematching puzzles, my variation there was actually the second puzzle inspired by them that I had found recently. The first was this set of 2\u00d72 square tiles with one cell being marked with 2 orthogonal or diagonal arrows. (The tiles can be flipped.) <\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><a href=\"https:\/\/puzzlezapper.com\/blog\/wp-content\/uploads\/2024\/05\/quadrant-circuit-1.png\"><img loading=\"lazy\" decoding=\"async\" width=\"655\" height=\"650\" src=\"https:\/\/puzzlezapper.com\/blog\/wp-content\/uploads\/2024\/05\/quadrant-circuit-1.png\" alt=\"\" class=\"wp-image-1177\" style=\"width:497px;height:auto\" srcset=\"https:\/\/puzzlezapper.com\/blog\/wp-content\/uploads\/2024\/05\/quadrant-circuit-1.png 655w, https:\/\/puzzlezapper.com\/blog\/wp-content\/uploads\/2024\/05\/quadrant-circuit-1-300x298.png 300w, https:\/\/puzzlezapper.com\/blog\/wp-content\/uploads\/2024\/05\/quadrant-circuit-1-150x150.png 150w\" sizes=\"auto, (max-width: 655px) 100vw, 655px\" \/><\/a><\/figure><\/div>\n\n\n<p>Part of the inspiration to use arrows may have come from the game of Trippples, <em>[siccc]<\/em> which uses a complete set of fixed square pieces with arrows in three directions. I recently read about Trippples in <a href=\"https:\/\/www.abstractgames.org\/uploads\/1\/1\/6\/4\/116462923\/abstract_games_issue_7.pdf\">issue 7<\/a> of <a href=\"https:\/\/www.abstractgames.org\/\">Abstract Games magazine<\/a>. Once I had these squares with arrows, a puzzle challenge seemed natural: connect the arrows into a single path, which may not enter any cell with arrows in any direction that does not correspond to an arrow.<\/p>\n\n\n\n<p><strong>Problem 61:<\/strong> Find a closed circuit using these pieces. I spent enough time finding the path above; I suspect that a closed circuit may be solvable if you have the <a href=\"https:\/\/polyominoes.blogspot.com\/2024\/02\/enneiamonds-again.html\">patience of a Lewis Patterson<\/a>, which I do not.<\/p>\n\n\n\n<p>One element I like to consider in puzzle design is <em>non-locality<\/em>. A puzzle exhibits non-locality if, when you are placing a piece, you must consider pieces that are not immediately adjacent. Most polyform and edgematching puzzles are generally local. If half of a puzzle frame is filled, pieces in the interior of the filled region do not directly affect how new pieces can connect to the edge of that region. (Of course, I am eliding the fact that they reduce the set of remaining pieces that are available to place.) In the above puzzle, the empty space allows long distance connections, turning path-making into a non-local problem.<\/p>\n\n\n\n<p>My Color Tubes puzzle from my Edge Collection Connection set of edgematching card puzzles was also a path puzzle with non-local considerations. I neglected to introduce it on the blog back when I produced the set, so let&#8217;s remedy that now.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><a href=\"https:\/\/puzzlezapper.com\/blog\/wp-content\/uploads\/2024\/05\/color-segments-3.png\"><img loading=\"lazy\" decoding=\"async\" width=\"411\" height=\"411\" src=\"https:\/\/puzzlezapper.com\/blog\/wp-content\/uploads\/2024\/05\/color-segments-3.png\" alt=\"\" class=\"wp-image-1179\" srcset=\"https:\/\/puzzlezapper.com\/blog\/wp-content\/uploads\/2024\/05\/color-segments-3.png 411w, https:\/\/puzzlezapper.com\/blog\/wp-content\/uploads\/2024\/05\/color-segments-3-300x300.png 300w, https:\/\/puzzlezapper.com\/blog\/wp-content\/uploads\/2024\/05\/color-segments-3-150x150.png 150w\" sizes=\"auto, (max-width: 411px) 100vw, 411px\" \/><\/a><\/figure><\/div>\n\n\n<p>The configuration shown is a solution to the challenge of placing the pieces so that each tube has three segments of three different colors. Segments can break in the middle of a card, or at a connection across a card boundary with non-matching colors. (Here, the cards cannot be flipped over; the back sides of the cards contain a second, related puzzle.) Other challenges for the cards are placing them so there are two differently colored segments, or four. This was definitely more of a &#8220;designed&#8221; puzzle than a &#8220;discovered&#8221; puzzle, which was a bit of a departure for me. I&#8217;ll have another excuse to muse about the distinction in a future post, but at this point I&#8217;ve hinted at more than one future post, so they can&#8217;t all be the next one.<\/p>\n\n\n\n<p>With a couple of instances of non-locality under our belts, can we say anything useful about it as a puzzle design tool? In the case of Color Tubes, I think it gives it a little more depth than a typical 3\u00d73 edgematching puzzle, which would seem to be welcome. In the arrow path puzzle, it adds difficulty and complexity, but the result is a little too much difficulty and complexity, at least for my tastes. It is a spice that should be judiciously applied. But then, so is hinting at coming posts, and that won&#8217;t stop me from teasing more material about non-local puzzles in the near future!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I promised two more path puzzles in part 1, and their time has come.
