Buku Kakuro

The goal of Kakuro is similar to that of Sudoku: Using pure logic as well as simple addition and subtraction calculations, players fill empty cells with numbers from 1 through 9 without repeating values in anycolumn and row. Clues, which are actually the sum of several adjacent cells, are found above each column and to the left of each row. Buku Kakuro offers countless hours of Kakuro puzzle fun and even teaches you how to play.
