X-Treme Kakuro

Kakuro puzzles (also known as cross sums) are like a combination of crosswords and sudoku: Each clue in the grid tells you the sum of the digits in its answer, and just like sudoku, digits are never repeated within an answer. From this simple premise, extremely challenging puzzles can be constructed, and that’s just what Conceptis Puzzles has done in this brand-new collection of kakuro puzzles sure to delight logic puzzle fans of all kinds. But there’s an added twist that sets this collection apart: in standard kakuro, you use the digits one through nine. But here, the numbers go up to ten! This simple change means readers can’t rely on old solving habits, which adds a level of difficulty perfect for solvers looking to stretch their mental muscles.
