If you look at it from a plane, it is impossible, but from a three-dimensional point of view, it is still possible. Fold the picture into a triangle along the vertical line first, and then go.

Each cell 6 is a minimum problem. It is impossible in a small 2×3 grid, so it is impossible. Three rows are even impossible. Odd lines should be unique among the three solutions.

Game introduction

"Rearrange the Nine Palaces" means "Rearrange Nine palace map". This is based on the popular mathematical game "Vertical and Horizontal Diagram" (also called "Rubik's Cube" or "Rubik's Cube Array"). The origin of Jiugong Game can be traced back to the "Hutuluo Book" in China's ancient mythology and history.

Luoshu is the most basic 3×3 Rubik's cube array and the third-order Rubik's cube in mathematics. There are many vertical and horizontal diagrams in the mathematics books of Tang and Song Dynasties, and on this basis, the game of rearranging the nine palaces has emerged. At present, the earliest forms we know still appear in written records.
