Kakuro – crossword with sums
Kakuro is a number crossword: fill the white squares with the digits 1–9 so that every run adds up to the sum given in its clue – and no digit is repeated within the same run. Every grid here is handmade and verified to have exactly one solution.
How to play
Kakuro looks like a crossword, but instead of words you fill in digits. The dark squares hold the clues: a number in the upper-right triangle is the sum of the white run running to the right, and a number in the lower-left triangle is the sum of the run going down. Fill every white square with a digit from 1 to 9 so each run adds up exactly to its clue.
The golden rule is that a digit may never be repeated inside the same run. So a run of two squares that sums to 4 can only be 1 + 3 (or 3 + 1), never 2 + 2. That single rule is what makes each puzzle solvable by pure logic – start with the short runs and the extreme sums, where only a few combinations fit. Click a square and type with the on-screen keypad or your keyboard; use the arrow keys to move around.
