Rules

• Place digits 1-9 in each row, column and region exactly once.


• Full Rank: Rows and columns make different nine digit numbers when read from either sides, which are ranked from the smallest to the largest with rank 1 being the smallest number. The rank numbers are placed just outside the grid and represent the rank of that row/column read from its direction.


• White kropki dots connect two consecutive numbers, and black kropki dots connect two numbers where one is double the other. Not all dots may be given.

Difficulty 2-3
