In the process of solving the fourth-order Rubik's Cube, we often encounter various problems and challenges. However, with the seven-step reduction method, we can easily solve these problems and restore the perfect fourth-order Rubik's Cube.
Step 1: Diagonal reduce.
First of all, we need to mark the six faces of the fourth-order Rubik's Cube with different colors so that we can proceed with the subsequent restoration steps. Then, with a series of turns, we can turn each face of the fourth-order Rubik's Cube into a single color. This process is known as diagonal reduction.
Step 2: Merge the center blocks.
On the basis of diagonal reduction, we need to merge the center blocks. This step requires us to carefully observe the center block of each face and return the center block of each face to the correct position through a series of rotations.
Step 3: Complete the first layer.
After completing the homing of the center block, we need to proceed to restore the first layer. This step requires us to carefully observe the edges of each face and return the edges of each face to the correct position through a series of rotations.
Step 4: Complete the second layer.
After completing the first layer, we need to move on to the second layer. This step requires us to carefully observe the center block and edge of each face, and through a series of rotations, the center block and edge block of each face are returned to the correct position.
Step 5: Complete the third layer.
After completing the second layer, we need to move on to the third layer. This step requires us to carefully observe the center block and edge of each face, and through a series of rotations, the center block and edge block of each face are returned to the correct position.
Step 6: Complete the fourth floor.
After completing the third layer, we need to move on to the fourth layer. This step requires us to carefully observe the center block and edge of each face, and through a series of rotations, the center block and edge block of each face are returned to the correct position.
Step 7: Adjust the order.
The final step is to adjust the order. We need to arrange the six sides of the fourth-order Rubik's cube in the correct order through a series of rotations.
