The basic solution of digital Huarong Road is just like the Rubik's Cube solution. Let's start the teaching steps. First, for the first line, move 1, 2, 3 to the target position one by one. This step does not require any skill, just move the three numbers one by one, regardless of other numbers.

When moving the number 4, first move it below the target position, move the two numbers on the left of the same row 4 to the right by one space, and then move the first row 1, 2, 3 to the left by one space counterclockwise. At this time, you can move the number 4 to the target position in the upper right corner, remove the irrelevant number to the left of the number 4, and rotate the integer of 1, 2, 3 clockwise to the right by one grid, so that the first line will be reversed. The second line is the same as the first line.

Next is the third solution. If 10 is below 9 instead of on the right, a solution is needed. In this case, 10 needs to be hidden in the square on the right, so that 9 can move freely in the square on the left. You can now move 9 to the left of 10. This step only looks at 9 and 10, without considering other numbers. 9 and 10 can match to 1 1, 12.

If 10 and 1 1 appear in the same box, the solution is the same as above. You can move 9, 10- counterclockwise to the left grid, and then move 65438+. So we can arrange the third row.

All aligned 9, 10, 1 1, 12 move two spaces counterclockwise to the left, 13, 14, 15 move two spaces counterclockwise to the right. 13 and 65445 are found at this time. Then move 9 clockwise by two squares to 15, and that's exactly right.
