Opis

100 Arrow Sudoku Puzzles with solutions included in an attractive book. Arrow sudoku is an absorbing sudoku variant, with lots of subtle logical rules that can be applied to help solve the puzzle. As with normal sudoku you must place the numbers 1-9 once in each row, column and 3x3 box. However the grid also contains arrows which give the puzzle its distinctive name and look. The number in the circle at the start of each arrow is the sum of the numbers along the body of the arrow. This sets up an intriguing interplay between the head and body of the arrow, and indeed often between different arrows in the grid too. By using standard sudoku solving logic combined with the novel types of logic introduced by the arrows, you will be able to find the unique solution for each puzzle (no need to ever guess). For anyone who likes sudoku but is looking for a different or tougher challenge, then this collection of 100 arrow sudoku could be just what you're looking for
