Universal Kakuro

Description

Available for print / Web / mobile

Kakuro is a cross between traditional crosswords and Sudoku. The idea behind Kakuro is very simple. Just like Sudoku, you must fit the numbers 1 to 9 into a grid of squares so that no number is repeated within a defined area. And just like a crossword, there’s a grid of filled blocks and clues to solve.

Kakuro puzzles are best solved using logic. Some of the same logic can be used as in Sudoku, but you also need a bit of math because with Kakuro there is a second constraint: Not only must the numbers not repeat within a clue run, they also must add up to given totals — these totals replace traditional word clues found in a crossword.

The clues and answer sequences run both horizontal and vertical in each 14×14 grid. And, like many daily puzzles, the difficulty increases throughout the week.
