1. There are two corner blocks in the top layer that are not the same color as the top center block. So according to the 2 after 4 left (2 after that is to say two color block color is not the same when the two color block white side towards the back of the cube. 4 left is another case in which the 4 is not in the top layer is not in the top layer of the corner of the block white towards the back of the cube) placed after the cube to do the small fish 1 (12 can be) the formula is: the right side of the counterclockwise 90, the top of the counterclockwise 90, the right side of 90, 90, 90, 90, 90, 90, 90, 90 counterclockwise, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90, 90 The formula is: right 90 counterclockwise, top 180, right 90 clockwise.
2. At the top, there are 3 corner blocks and the center block of different colors. This according to the fish head next to the color block direction to determine to do small fish 1 or 2. small fish 2 formula: left clockwise 90, the top clockwise 90, the left counterclockwise 90, the top clockwise 90, the left clockwise 90, the top 180, the left counterclockwise 90. OK. the top layer put together.
3. The top 4 corner blocks and the center color block are different colors, according to the 2 after 4 left placement of the Rubik's Cube to do small fish 1 or 2 can be to step 2.
