An N×N chessboard has N²-1 number squares and a space. You can slide the square adjacent to the space to the space at a time. The goal is to slide all numbers from left to right and top to bottom, leaving spaces in the lower-right corner.
The classics are 3×3 (8 digits) and 4×4 (15 digits). The idea of solving the problem is to arrange the first line first and then move forward line by line. The last two lines require special skills and cannot be processed separately.
Not all initial states have solutions-it is mathematically possible to prove that exactly half of the permutations have no solutions. The game will be generated to ensure that the state after the upset has a solution. CSS Grid layout, sliding CSS transition animation.
In the Digital Huarong Road game, slide the number squares in the N×N grid and arrange them in order. The spaces are in the lower right corner to complete it.
