Why kakuro is worth learning
If you enjoy sudoku, kakuro is the natural next step. The no-repeat rule will feel familiar, and the clue sums add a second layer of deduction that sudoku does not have. The arithmetic never gets harder than adding a few small numbers; the pleasure is in the logic, not the math. Kakuro has run in newspapers and puzzle magazines for decades under names like Cross Sums and Kakkuro, and a well-set grid rewards the same patient, satisfying reasoning as a good crossword.
