Amazing Arrowdoku
Welcome to Amazing Arrowdoku, which features 100 arrowdoku puzzles and solutions. Arrowdoku is a sudoku variant. The solver is required to place each number from 1 – 9 exactly once in each row, column and 3x3 bold-lined box that comprises an arrowdoku grid, as with standard sudoku puzzles. However, there is also a range of grey arrows included in the grid, which give this puzzle its name and its distinctive appearance. The cells placed along the body of an arrow sum to the number given in the circled cell at the start of that arrow. A number may repeat along the path of an arrow, only if repeating it does not break the rule that no number can repeat in any row, column or 3x3 box. Solutions are featured at the back of the book for the solver to check their answers.
