The grid contains some bordered or colored cells that cannot be part of the loop. Black cells must be outside the loop; white cells (with heavy borders) must be inside the loop. Numbers and arrows refer to the total sum of the lengths of loop segments in the given direction. (An equivalent way to understand these values is to count the number of cell borders crossed by the loop in that direction.)<\/p>\n<p><b>Answer String:<\/b> Enter the length in cells of the horizontal loop segments from left to right in the marked rows, starting at the top. If the loop only has vertical segments in the marked row, enter 0. Separate each row\u2019s entry with a comma. This example has the key \u201c2,21\u201d.<\/p>\n<p><b>(Brief) History of Castle Wall:<\/b> Castle Wall is an original loop puzzle style created by Palmer Mebane in 2009; the first examples were posted on his blog <a href=https:\/\/mellowmelon.wordpress.com\/category\/puzzle-types\/castle-wall\/>Melon&#8217;s Puzzles<\/a>.<\/p>\n<p><b>History of this example:<\/b> This Castle Wall was written by Thomas Snyder.<\/p>\n<p><b>Sources for Castle Wall:<\/b> Follow this link for more <a href=\"https:\/\/www.gmpuzzles.com\/blog\/category\/loop\/castle-wall\/\">Castle Wall puzzles<\/a> on this website and this link for other Castle Wall puzzles from <a href=\"https:\/\/mellowmelon.wordpress.com\/category\/puzzle-types\/castle-wall\/\">Palmer Mebane&#8217;s old blog<\/a>.
