Arrow Sudoku: 200 Puzzles

Product Information

In most Arrow Sudoku puzzles each circled cell will only have a single arrow originating from it. However, there is nothing stopping there being multiple arrows coming out of the same cell. Your solving tips are good, although I'd worked those out for myself, and still haven't finished one!

I've finished off the 2 issues of Arrow Sudoku Magazine. Any chance of some more being produced please? So, for example, if we consider the circle in the very center of the grid, you’ll notice that the cells its arrow covers all have their digits given. In this case it’s a 7 and 2. This means the center cell must be a 9.When solving arrow sudokus, it can be particularly useful (in a 9x9 puzzle) to see if there are any 9's that you can place right away based on the direction and location of the arrows.

In harder arrow sudoku puzzles, you may need to use the fact that you know a number must go inside the arrow but you don't know where, then use that to eliminate it from the rest of the region it fully intersects.These puzzles are so addictive. I still haven't solved one completely, but feel that getting through even half And of course you use the numbers you've been given and cross them out in all the other boxes in the same square, column, or row. 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. If you look at the sample image, and sample solution particularly, it will help you to see how the arrows work: the number in the circled cell is the sum of the numbers along the path; thus if there is a 2 and a 3 along the path of an arrow of length two, then the circled cell contains 5, given 2 + 3 = 5, and so on.

How much do you know about the Bard? It's time to find out with this fun quiz that contains 20 questions about the life and times of William Shakespeare...In arrow sudoku, the aim is to place the numbers from 1 - 9 once each in a row, column and 3x3 box. But you will notice that there are two differences: firstly there are many fewer given starting numbers than in an ordinary sudoku, and secondly of course there are arrows. The two are related. Each Sudoku puzzle will have one unique solution. In other words, each cell is only supposed to have one number in it. How do you recognize a swordfish pattern? You look for cells with common candidate numbers that can be chained together like in example D. If you start on, say, the top-left red cell. Then you draw a line either vertically or horizontally until you reach another cell containing the same candidate number. Then you repeat this pattern until you return to the original cell. If you reach the original cell, you have a swordfish pattern! 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.

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 circle at the top of each arrow contains a number that is the sum of the numbers that appear along the body of the arrow, ending in the square with the arrow head.Well i feel much better having read the above comments,I too, find Sudokarrow quite challenging.I am pleased to say that I have solved some but it has taken me a few days!!
