Your solving tips are good, although I'd worked those out for myself, and still haven't finished one! Thank goodness they're not in the i (a great newspaper!) every day. I still haven't solved one completely, but feel that getting through even half Have any of the tips on the body of this page proved useful? do you get a fair way through or is it right at the beginning. How much of the puzzles do you solve before getting stuck. Generally speaking you'll have a large number at the top of an arrow and small values along the path of the arrow. The key is often to work out the possible values along the arrows as per the tips above. The sudokuarrow puzzles are definitely harder than standard sudokus and will take longer to solve. I find the i sudukoarrow puzzles hard and pretty much always fail! How would you rate them? I came looking for help as I spent most of Sunday trying to complete the puzzle and failed. Yes, there is a collection of these puzzles you can download and print online at the Puzzle Magazines site here: Great to hear that you enjoy these puzzles! good luck!Ĭategory: sudoku variants | Keywords: arrow sudoku Comments:I am addicted to these Sudokarrow puzzles but as you quite correctly suggest, have only found them in the i on Saturday. Furthermore, the cells at the start and end of the arrow can contain only 1 or 2, and the three in the middle can only contain 1,2,3,4.īy working through each arrow in this way, together with the standard solving rules, you can reduce the options without any guesswork, and start to place numbers - which will then give you more information to feed-in to the arrows, and you can work interactively back and forth between the information the arrows give you and the standard sudoku rules until the puzzle is complete.Įach arrow sudoku - or sudokarrow - has one solution that can always be reached without guesswork, so if you get stuck, stay patient and look for any deductions you may be missing. Since the three cells are in the same region, then the lowest total for them is 1 + 2 + 3 = 6, whilst there are two cells in other regions, so the lowest for those is 1 thus the circled cell contains either 8 or 9, with all other values instantly eliminated. Note that the body of the arrow goes through 5 cells, and that three of them are in the same region. Look now at the arrow region whose head is the second cell in row 6 (to the right of the given '2'). It just may take a little while to build up momentum. This only leaves the first cell in the row - containing a circled cell - that can hold 9, so it can be placed immediately!īy working out the possible values of numbers along the path of an arrow and at the head, you can quickly whittle down the options for cells in the grid and start solving. And as it turns out, cells 2, 3, 7, 8, 9 in the bottom row are all along the path of an arrow, and therefore cannot contain 9. It can't be in cells 4 - 6 of the bottom row because there is already a 9 in that box. It may not be immediately obvious, but it can be placed outright. Ask yourself where the 9 can be placed in the bottom row. Whilst this may not seem like much, it can lead to placements straight away! Look at the sample puzzle to the right again. At the most basic level, you know that the circled cell cannot contain the 1, and each cell along the path of the arrow cannot contain 9. Thus if you look at the first circle in cell two of the puzzle, the number therein is the sum of the first and eleventh cells of the grid, so if those two cells contain 6 and 3, then the circled cell contains 9, as the sum of 6 + 3 = 9.Īrrows provide lots of information that helps you to solve the puzzle. 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. But this is compensated by the fact that the arrows provide additional information - if you know how to access that information! In addition to the arrows, it will immediately be noticed there are many less givens than with a standard sudoku puzzle. If you have done, then the chances are that you buy the i newspaper on Saturday, and if so you'll be familiar with the striking visual of this puzzle, as per the image at right: Arrow Sudoku PuzzlesArrow Sudoku puzzles are an enjoyable sudoku variant that is rarely seen in print.
