How to Play Kakuro
Objective: Fill all white cells with digits from 1 through 9 so that the sum of each run matches the clue associated with it.
Rules:
Each number in a horizontal or vertical run must be unique (no repeating digits in the same run).
A clue number to the left of a run specifies the sum of white cells in that horizontal row. In a split clue cell, this number sits in the upper-right corner.
A clue number above a run specifies the sum of white cells in that vertical column. In a split clue cell, this number sits in the lower-left corner.
Controls & Features:
Tap any white cell to select it, then choose a number from the keypad or keyboard (1-9).
Choose a Difficulty (Easy 4x4 / Medium 6x6 / Hard 8x8) — every puzzle is procedurally generated and computer-verified to have exactly one valid solution before it ships.
