A Sudoku rule (defined in PSE) is below:
A Sudoku is a puzzle consisting of a grid to be filled with symbols, such that each constraining unit contains each symbol exactly once.
The typical example is a 9x9 square to be filled with the numbers 1 to 9, where the constraining units are rows, columns, and 3x3 blocks.
Number Picker: 11 22 33 44 55 66 77 88 99
Note: the symbols |, -, + are just for bold lines in Sudoku, not any clue.
