Sudokids size 4 by 4 resolution follows that of the classic 9x9 sudokus, the player must enter numbers from 1 to 4 according to the rule: maximum 1 per line and 1 per column.

Generally 4x4 sudoku do not use the blocks / regions (because this is often not necessary) but there may be some with irregular shapes (and not necessarily 2x2). By default, the dCode solver considers that there is none and returns all solutions.
