Kakuro by Solvyne

Challenge your mind with Kakuro, the captivating cross-sum puzzle that combines the logic of Sudoku with the satisfaction of arithmetic. Fill white cells with digits 1-9 so that each horizontal and vertical run adds up to its clue number — without repeating any digit within a run.

Each clue cell displays target sums: the number above the diagonal is for cells to the right, and the number below is for cells below. Learn essential combinations like knowing that a sum of 3 in two cells can only be 1+2, and use cross-referencing between intersecting runs to crack even the toughest puzzles.

With hundreds of handcrafted puzzles across multiple difficulty levels, Kakuro delivers hours of brain-training entertainment. Track your progress, compete on leaderboards, and sharpen your logical thinking one puzzle at a time.
