Daily Windoku

Here is your Daily Windoku puzzle. This the entry for Thursday, April 18, 2024.

Windoku, also known as the NRC Sudoku variant, Hyper(su)Doku or Sudoku Hyper, has all the rules of a “vanilla” Sudoku, with one addition: The four window panes with the blue background color must also contain digits 1 through 9. Many solving techniques for normal Sudoku can be used, but you will also need to use the 4 windows panes to check for singles, pairs, triples, and their interaction with rows, columns and boxes. The way the 4 window panes are positioned allow you to find 5 additional groups of cells where only digits 1 through 9 can go. These implied rules can prove very useful when you try to solve this puzzle.

To facilitate you using a Sudoku helper program, you can copy the number string below the puzzle and paste it into your program. Before you paste it, switch the program to the Windoku variant. If you paste it as a regular Sudoku, you will receive a warning that it has multiple solutions.

level: 42, requires: N2,H2,CP,SK,2S
