Giant Kakuro
Welcome to this fantastic collection of 100 giant kakuro puzzles, placed in a 20x20 grid size. To solve a kakuro puzzle, the solver is required to fill the kakuro grid with numbers so that the sum total of each run of white cells in a row or column matches the number at the start of it. The solver may only use numbers from 1 – 9 and may not repeat a number within a run of cells. Therefore if you need to make '6' off three cells then it cannot be 2,2,2 as that has repetition, leaving a combination of 1,2,3 as the only possible solution. Each kakuro puzzle has a unique solution that can be reached without guessing. Solutions are featured towards the back of the book if the solver needs to take a look if they get stuck while completing the kakuro puzzles.
