Isodoku is a Japanese nanpure variation, created before the return of &#8220;Sudoku&#8221; to the West. (If you know more about the original author\/publication of this style, please tell us). The English name is short for <u>Iso<\/u>metric Su<u>doku<\/u>, with the apparent 3d effect arising from an isometric projection; this genre is also sometimes called &#8220;3d Sudoku&#8221;. <\/p>\n<p><b>History of this example:<\/b> This Isodoku was written by Thomas Snyder for the 2012 US Sudoku Team Qualifier.<\/p>\n<p><b>Sources for Isodoku:<\/b> Follow this link for <a href=\"https:\/\/www.gmpuzzles.com\/blog\/tag\/isodoku-2\/\">Isodoku puzzles<\/a> on this website.
