Kakuro: Cross Sums Puzzle

Play Kakuro, the classic cross sums number puzzle! Fill the white cells with digits from 1 to 9 so that every run adds up to the clue in the dark cell, and never repeat a digit inside a run. Pure logic, no guessing, and a great way to train your mind. If you like number crosswords, math puzzles or logic puzzles for adults, this is your game.

HOW TO PLAY
• A number at the top right of a dark cell is the sum of the run of cells to its right.
• A number at the bottom left is the sum of the run below it.
• Use each digit only once inside a run.
• Every puzzle has exactly one solution.
• Tap a clue to see every set of digits that makes its sum.
