Basic Rules for All Grid Sizes 

The core principle of Sudoku remains the same, regardless of grid size

Each column must contain all possible numbers without repetition.

Each smaller subgrid (box) must contain all possible numbers without repetition.

The difficulty increases with grid size, but the logic remains consistent.
