At the beginning of the game, some grids are already filled with numbers (called "given numbers"), and players need to deduce the numbers of the remaining grids based on these numbers.

Each column (9 grids) must contain numbers from 1 to 9, and they cannot be repeated.

Each 3x3 grid (9 grids in total) must contain numbers from 1 to 9, and they cannot be repeated.

Problem-solving skills:

Unique candidate number method: If a grid has only one possible number, then this number is the solution to the grid.

Elimination method: Determine the number of a grid by eliminating the existing numbers in a row, column, or grid.

Block elimination method: Use the distribution of numbers in the grid to eliminate possible numbers in certain grids.
