I conquered this one in the past but it wasn&#8217;t all too fun.  Trying this again&#8230;I don&#8217;t know if it really is.  The eight-faced beast challenges my brain&#8230;I guess that&#8217;s a good thing.  Anyways, algorithms that I keep forgetting&#8230;<\/p>\n<p>Years later I&#8217;m updating this section to be a bit more clear.  I&#8217;ve gotten a bit better at things by now (February 2022, to be specific) so let&#8217;s hope it&#8217;s even easier in the future!!!<\/p>\n<p><b>Step 1<\/b>: Get 3 corners<br \/>\nThis is intuitive.  Get all the corners on one color&#8217;s face set up properly.  Don&#8217;t worry about anything else.  <\/p>\n<p><b>Step 2<\/b>: Solve remaining corners<br \/>\nPlace your first face downwards and scope out the top.  You&#8217;re going to get the next three corners aligned.  We&#8217;re going to use the standard algorithm here, but where we begin depends on how things turn.  <\/p>\n<p>You should have one corner piece in the proper spot here and aligned properly.  (I suppose if you don&#8217;t, do this algorithm twice).  <\/p>\n<p>Holding the pointy corner towards you, you&#8217;ll do the traditional D, D, U, U.  <\/p>\n<p>If you start R&#8217;, L, R, L&#8217;<br \/>\n<Ul><\/p>\n<li>Both the front and right corners will swap spots clockwise <b>and<\/b> they&#8217;ll rotate.\n<li>The left corner will slide right but won&#8217;t rotate.\n<li>Thus, keep the properly-aligned piece in the left corner and do this algorithm.\n<\/ul>\n<p>If you start L, R&#8217;, L&#8217;, R<\/p>\n<ul>\n<li>Both the front and left corners will swap spots counter-clockwise and they&#8217;ll rotate.\n<li>The right corner will slide left but won&#8217;t rotate.\n<li>Thus, keep the properly-aligned piece in the right corner and do this algorithm.\n<\/ul>\n<p><b>Step 3<\/b>: Solve edges<br \/>\nNow we&#8217;re going to rotate edge triangles.  This 3&#215;3 algorithm is slightly modified and is done with the right and top faces.  You&#8217;ll hold the puzzle with a tip facing you, but angled downwards so the algorithm can be done using the top layer.  (2024 translation: Hold with the V looking at you)  This will rotate three edges, either clockwise or counter-clockwise and will require deconstruction\/reconstruction to get everything in order.  I try to refrain from using two moves-algorithm-undo those two moves b\/c my brain isn&#8217;t so smart.<\/p>\n<p>\n<u>Clockwise<\/u>: R, U, R&#8217;, U, R, U, R&#8217;, U<br \/>\n<u>Counterclockwise<\/u>: R&#8217;, U&#8217;, R, U&#8217;, R&#8217;, U&#8217;, R, U&#8217;<\/p>\n<p><b>Step 3<\/b>: 3-Cycle centers<br \/>\n<a href=\"https:\/\/slateman.net\/blog\/wp-content\/uploads\/2022\/05\/fto-petals.jpg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/slateman.net\/blog\/wp-content\/uploads\/2022\/05\/fto-petals-150x150.jpg\" alt=\"\" width=\"150\" height=\"150\" class=\"alignright size-thumbnail wp-image-4367\" \/><\/a>This moves the UR center to UL center to LL center (left face, left center)<br \/>\nUse the face with the 1 center and slice down.
