The puzzle was created around 1950 by Canadian Jacob E. Funk under the name &#8220;Cross Sums&#8221; and gained popularity in Dell puzzle magazines. Like its counterpart &#8220;Number Place&#8221;, now known as <a href=https:\/\/www.gmpuzzles.com\/blog\/sudoku-rules-and-info\/>Sudoku<\/a>, Cross Sums was brought back to Japan and became more famous under its foreign name. Kakuro is an abbreviation of the Japanese phrase Kasan Kurosu (\u52a0\u7b97\u30af\u30ed\u30b9, meaning addition cross).<\/p>\n<p><b>History of this example:<\/b> This Kakuro was written by Thomas Snyder.<\/p>\n<p><b>Sources for Kakuro Puzzles:<\/b> Follow this link for classic <a href=\"https:\/\/www.gmpuzzles.com\/blog\/tag\/kakuro+classic\/\">Kakuro puzzles<\/a> on this website and this link for <a href=\"https:\/\/www.gmpuzzles.com\/blog\/tag\/kakuro+variation-2\/\">variations on Kakuro puzzles<\/a>.

Generally, a Grandmaster Kakuro should have a symmetric layout of black cells or an interesting visual theme in the absence of symmetry. Not all clues need to be given, and single digit entries are rarely present and never clued. Sizes from 9&#215;9 and above are recommended (maximum aspect ratio of 2:1 if rectangular).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Rules: Enter a single digit from 1 to 9 into each white cell so that the sum of digits in each Across entry equals the value given to the left of the entry, and the sum of digits in each Down entry equals the value given above the entry.
