Center Dot Sudoku
About this puzzle
Sudoku - also known as "Number Place" - is a logic-based, combinatorial number-placement puzzle. The aim of Sudoku is to enter a number from 1 through 9 in each cell of a grid, most frequently a 9×9 grid made up of 3×3 subgrids. Each row, column and region must contain only one instance of each number.
This Sudoku variant is called "Center Dot Sudoku". The central cells of each region form an extra region that must also contain the numbers 1 through 9.
