Sudoku introduction:

DT is a math puzzle game developed in the United States and developed in Japan from the end of the 18th century. The jigsaw puzzle is a square shape of a three-cell-width × three-cell-height puzzle. Each cell is subdivided into a nine-cell-lattice. Fill in numbers ranging from 1 to 9 in each of the small cells, so that the numbers in each column and row of the big cells are not repeated.

The gameplay logic of DT alone is simple and the number arrangement is ever-changing. Many educators believe that data independence is a good way to train their brains.
