:thumbsup:There are two scenarios for pairing edge pieces on the 4x4 Rubik's Cube: diagonal and directly across from each other.
:bulb:To pair diagonal edge pieces, slice the layer, pair them up, and rotate them into the top layer.
:loudspeaker:To pair edge pieces directly across from each other, do a specific move to create a diagonal pair, then pair them up and rotate them into the top layer.
:hourglass_flowing_sand:When you have three pairs of edges left, pair them up one by one and rotate them into the top layer.
:mega:If you need further assistance or have questions, leave a comment or contact the creator directly.
