Sudoku Variants Series (113) - Compressed Sudoku
(Published on 26. January 2016, 00:00 by Richard)
For this Sudoku Variants Project I have planned to publish a different Sudoku variant every Tuesday. I will see how long it takes before I am running out of ideas.
Compressed Sudoku
Inspiration for this variant comes from Sudoku Cup #5
Solve online in Penpa+ (thx bbutrosghali!)
Fill in the whole grid with numbers from 1 to 9, so that no number is repeated within a row, a column, the four grey 3x3-blocks or the five outlined 3x3-blocks.
Solution code: Column 1, followed by column 4.
