Kakuro puzzles resemble crosswords which use numbers instead of words. Each "word" must add up to the number provided in the clue above it or to the left. Words can only use the numbers 1 through 9, and a given number can only be used once in a word. The aim of the game is to fill all the blank squares in the grid so that the numbers you enter add up to the corresponding clues. When the grid is filled, the puzzle is complete. Every kakuro has one and only solution, and can be solved through logic alone. Kakuro is a very elegant game, providing fabulous gameplay experience with 2400 unique games. All of them are verified to have only one possible solution! Kakuro is Sudoku's bigger brother. If you enjoy Sudoku then chances are you will really love Kakuro.
