Rubik's Cube OLL Corners

Case recognition

• Sune (fish)

  Sune (fish): exactly one corner on the top face shows yellow up, with the three yellow side stickers connecting into a "fish body" — the whole shape looks like a small fish.

  U align

  Apply formula

  Build: Sune (fish)

  Build the one-yellow-up Sune (fish) case.

  U align · fish head to front-left

  Rotate the U layer to put the fish head (the yellow-up corner) at the front-left corner (between the L and F faces).

  Sune · orient in one step

  With the fish head at front-left, do one Sune (R U R' U R U2 R') to finish corner orientation.

  Exactly one corner on the top face shows yellow up; the other three corners show yellow on their sides.

  The yellow-up corner is the "fish head", and the three yellow side stickers connect into a "fish body" — the whole shape looks like a small fish.

  The Sune formula R U R' U R U2 R' is one of the most-used OLL formulas. Memory aid: the first four moves R U R' U alternate, and the last three are R U2 R'.

  Sune formula

• Anti-Sune (reverse fish)

  Anti-Sune (reverse fish): exactly one corner on the top face shows yellow up (one-up, same as Sune); the difference is the side yellow stickers point the opposite way, so the whole shape looks like a reversed fish.

  U align

  Apply formula

  Build: Anti-Sune (reverse fish)

  Build the one-yellow-up Anti-Sune (reverse fish) case.

  U align · reverse fish head to front-left

  Rotate the U layer to put the reverse fish head (the yellow-up corner) at the front-left corner (between the L and F faces).

  Anti-Sune · orient in one step

  With the reverse fish head at front-left, do one Anti-Sune (R U2 R' U' R U' R') to finish corner orientation.

  Exactly one corner on the top face shows yellow up; the other three corners show yellow on their sides (one-up, same as Sune).

  The difference from Sune is the "tail" direction: the side yellow stickers point the opposite way, so the whole shape looks like a reversed fish.

  The Anti-Sune formula R U2 R' U' R U' R' is the inverse of Sune. The U2 is on the second move (Sune's U2 is on the fifth).

  Anti-Sune formula

• Two · same-face (Headlights)

  Two · same-face (Headlights): two corners on the top face show yellow up and are adjacent; the two non-up corners have their yellow stickers facing the same side face (like a pair of headlights).

  U align

  Apply formula

  Build: two · same-face

  Build the case with two adjacent corners up and the two non-up yellows on the same face.

  U align · to the starting orientation

  Rotate the U layer to bring the top face to the starting orientation for the first formula (the system auto-selects it).

  Formula · transition to a fish

  Do one Sune to transition the top to a fish case (one more application finishes it).

  Two corners on top show yellow up and are adjacent; the two non-up yellows sit on the same side face (headlights).

  The two non-up yellow stickers appear together on one side face, like a pair of headlights.

  The two-adjacent cases use a uniform flow: do one Sune to transition to a fish (one corner up), re-identify the fish and re-hold, then do one more to finish (2 formulas total). The system auto-selects the correct starting orientation and formula.

  Apply formula

• Two · opposite (Chameleon)

  Two · opposite (Chameleon): two corners on the top face show yellow up and are adjacent; the two non-up corners have their yellow stickers facing opposite side faces (not on the same face).

  U align

  Apply formula

  Build: two · opposite

  Build the case with two adjacent corners up and the two non-up yellows on opposite faces.

  U align · to the starting orientation

  Rotate the U layer to bring the top face to the starting orientation for the first formula (the system auto-selects it).

  Formula · transition to a fish

  Do one Sune to transition the top to a fish case (one more application finishes it).

  Two corners on top show yellow up and are adjacent; the two non-up yellows sit on opposite side faces (not together).

  The two non-up yellow stickers appear on opposite side faces, not together on one face.

  The two-adjacent cases use a uniform flow: do one Sune to transition to a fish (one corner up), re-identify the fish and re-hold, then do one more to finish (2 formulas total). The system auto-selects the correct starting orientation and formula.

  Apply formula

• Two corners up (diagonal)

  Two corners up (diagonal): two corners on the top face show yellow up, and they sit on a diagonal (not sharing an edge).

  U align

  Apply formula

  Build: two corners up (diagonal)

  Build the case with two diagonal corners showing yellow up.

  U align · to the starting orientation

  Rotate the U layer to bring the two diagonal yellow-up corners to the starting orientation (the system auto-selects it based on the formula).

  Formula · transition to Sune

  Do one formula to transition to a Sune case (one more application finishes it).

  Two corners on the top face show yellow up, and they sit on a diagonal on the top (not sharing an edge).

  The two yellow-up corners sit on opposite diagonals, with other corners between them.

  The diagonal case takes 2 steps: first do one formula to transition to a Sune case; after an AUF adjustment, do one more to finish. The system auto-selects the correct formula.

  Apply formula

• None up · one-pair (Pi)

  None up · Pi: none of the four top corners shows yellow up; two of the yellow stickers share one side face (a pair) and the other two are split across the remaining sides — overall a π shape.

  U align

  Apply formula

  Build: none up · one-pair

  Build the case with no corner up and only one same-face pair of side yellows.

  U align · to the starting orientation

  Look at the side yellow orientations and rotate the U layer to bring the top face to the starting orientation for the first formula.

  Formula · transition to a fish

  Do one Sune to transition the top to a fish case (one more application finishes it).

  None of the four top corners shows yellow up; among the side yellows only one pair shares a face, the other two are split (a π shape).

  Among the side yellows only one pair sits together on one face; the other two are each on other faces — overall a π shape.

  The no-corner-up cases use a uniform flow: do one Sune to transition to a fish (one corner up), re-identify the fish and re-hold, then do one more to finish (2 formulas total). The system auto-selects the correct starting orientation and formula.

  Apply formula

• None up · two-pair (H)

  None up · H: none of the four top corners shows yellow up; the four yellow stickers pair up onto two opposite side faces (two parallel bars — overall an H shape).

  U align

  Apply formula

  Build: none up · two-pair

  Build the case with no corner up and the side yellows forming two parallel bars.

  U align · to the starting orientation

  Look at the side yellow orientations and rotate the U layer to bring the top face to the starting orientation for the first formula.

  Formula · transition to a fish

  Do one Sune to transition the top to a fish case (one more application finishes it).

  None of the four top corners shows yellow up; the side yellows pair up onto two opposite side faces (an H shape).

  The side yellows form two parallel bars on opposite side faces — overall an H shape.

  The no-corner-up cases use a uniform flow: do one Sune to transition to a fish (one corner up), re-identify the fish and re-hold, then do one more to finish (2 formulas total). The system auto-selects the correct starting orientation and formula.
