Because of the arrow regions in the puzzle, you will need more than just sudoku logic to solve arrow sudoku. You must also look at the possible values within the arrow: both for the total cell (circled) and the cells along the path of the arrow. It is this combination of sudoku logic with the interesting and sometimes subtle deductions that can be made from the arrow regions that make this such a compelling and interesting puzzle. All arrow sudoku have one solution that can be reached through logic alone: no guessing is required.

Is there a book? can I buy online? Arrow Sudoku PuzzlesArrow Sudoku puzzles are an enjoyable sudoku variant that is rarely seen in print. This method can work when you look at cells comprising a rectangle, such as the cells marked in red. In this example, let's say that the red and blue cells all have the number 5 as candidate numbers. Now, imagine if the red cells are the only cells in column 2 and 8 in which you can put 5.In addition to the standard Sudoku rules, in Arrow Sudoku the digits in the circled cells must be the sum of the digits along the arrow point out of it. These are fiendish! I have sometimes found help from the following. Where three numbers which are all different add to a circle, there are only seven combinations, adding to between 6 and 9. All but one of them contain '1'.

The arrows indicate certain regions of the puzzle in which the numbers are of significance. Specifically, the cell that is circled is the sum total of the other cells along the path of the arrow. Therefore if the three cells along the path of an arrow should contain 1,2,3 then the circled cell contains 1+2+3=6. In example A, we've plotted in some candidate cells for the number 3. Now, assume that in column 2, 4, 7 and 9, the only cells that can contain the number 3 are the ones marked in red. You know that each column must contain a 3. Forcing chain can actually help you determine exactly what number a certain cell must hold. Unfortunately, the technique is not the easiest to utilize. Look at the example below. Let us assume that the candidates in the red cells are the sole candidates for those cells.
