One of the most interesting elements of solving arrow sudoku is that the circle cell and the path of the arrow interact - by updating the options for one you may find you can update the options for the other, and then those can again be used to update the circled cell. Since 2021, we have posted some extra difficult Sunday Stumpers, about once a month. These will be quite tough puzzles, but with a logical path to be found (and solution videos to help). This fifth Sunday Stumper of 2022 is a combination of Arrow Sudoku and Thermo-Sudoku by Jonas Gleim.

However, there is nothing stopping there being multiple arrows coming out of the same cell. Sudoku is a brain challenging number game, played on a 9x9 sudoku board. The sudoku board is broken down into nine 3x3 squares. The object of the sudoku game is simple. Every row, column, and 3x3 box in the sudoku board must contain the digits 1 through 9 only once! As the difficulty progresses, the sudoku game becomes harder, and you'll have to employ more advanced and strategic logic to solve the puzzles.

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!! Whilst this may not seem like much, it can lead to placements straight away! Look at the sample puzzle to the right again. Ask yourself where the 9 can be placed in the bottom row. It may not be immediately obvious, but it can be placed outright. It can't be in cells 4 - 6 of the bottom row because there is already a 9 in that box. 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. This only leaves the first cell in the row - containing a circled cell - that can hold 9, so it can be placed immediately! 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.

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. Answer String: Enter the row/column marked “A”, followed by a comma, followed by the row/column marked “B”. Rows are entered from left to right and columns from top to bottom. This example has the key “351876294,617354928”. For instance if you know an arrow must contain 1,3,5 or 2,3,4 then you know it must contain a 3 somewhere. If that arrow is fully inside a 3x3 box region in the ordinary sudoku puzzle, then you can eliminate 3 from all other cells in the 3x3 box that are not along the path of the arrow. To enter a number, press that number on the keyboard. If there is already a number in that square, it will be overwritten.

Tip 2: Break the grid up visually into 3 columns and 3 rows. Each large column will have 3, 3×3 grids and each row will have 3, 3×3 grids. Now, look for columns or grids that have 2 of the same number. Logically, there must be a 3rd copy of the same number in the only remaining 9-cell section. Look at each of the remaining 9 positions and see if you can find the location of the missing number. Design rules for contributors: A Grandmaster Arrow Sudoku will have a unique solution that can be reached by logic alone. Generally, a Grandmaster Arrow Sudoku has a symmetric layout of numbers and arrows or a visually interesting theme that does not need symmetry. Arrows can exit and reenter the grid, and on rare occasions cross other arrows or circles provided it is clear what each component arrow is. Multiple arrows can arise from a single circle. Given numbers should not appear anywhere on the arrow shapes. Arrow Sudoku PuzzlesArrow Sudoku puzzles are an enjoyable sudoku variant that is rarely seen in print. It can take a while to start placing numbers with arrow sudoku as you go about working out the various options for each cell, but once you get going the puzzle soon builds momentum and there is lovely solving interplay between the arrows and their values and the standard sudoku rules.

Sudoku is a fun puzzle game once you get the hang of it. At the same time, learning to play Sudoku can be a bit intimidating for beginners. So, if you are a complete beginner, here are a few Sudoku tips that you can use to improve your Sudoku skills.

In this video we look at the rules of futoshiki and how they work. We examine the greater than and less than signs that are the key addition to standard sudoku rules. Take a look if you're tempted to have a go at this puzzle type... In addition, the grid contains grey arrows. The number to be placed in the circled cell at the start of each arrow is the sum of the digits that fall along the path of the arrow. Category: 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. Is there a book? can I buy online? If all but one cell in a region for instance lie along the path of an arrow and are not at its head, then none of those can contain 9.There is a point at which it suddenly starts to go faster and you know you're going to get through it--an elusive feeling I'd been chasing for months!! History of this example: This Arrow Sudoku was written by Thomas Snyder for the 2010 Hungarian Sudoku Championship. Rules: Standard Sudoku rules (insert a number in the indicated range into each cell so that no number repeats in any row, column, or bold region). Some arrow shapes are in the grid; the sum of the numbers along the path of each arrow must equal the number in the circled cell. Numbers can repeat within an arrow shape.

I came looking for help as I spent most of Sunday trying to complete the puzzle and failed. Thank you for the tips. I shall not be beaten.

There are two ways to play a Sudoku puzzle, you can just use the mouse/touchscreen, or you can use the mouse and keyboard. In addition to the arrows, it will immediately be noticed there are many less givens than with a standard sudoku puzzle. But this is compensated by the fact that the arrows provide additional information - if you know how to access that information! Your solving tips are good, although I'd worked those out for myself, and still haven't finished one! 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. 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.
