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? There are two ways to play a Sudoku puzzle, you can just use the mouse/touchscreen, or you can use the mouse and keyboard.

My method was to create a larger sudoku grid in Word, and in very small light type at the top of each box, put the numbers 1-9 (so they fit in one row, evenly spaced out). Then I re-drew the circles and arrows and given numbers in pen. 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. Arrow sudoku puzzles will have many fewer givens than a standard sudoku due to the fact that there is much more information to be gained that will help you solve the puzzle from the arrows.

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.

To enter a number, press that number on the keyboard. If there is already a number in that square, it will be overwritten. 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. Brief) History of Arrow Sudoku: Descended from Sudoku and arithmetic puzzles. Arrow Sudoku is a Japanese nanpure variation, likely created before the return of “Sudoku” to the West. (If you know more about the original author/publication of this style, please tell us). Tip 1: Look for rows, columns of 3×3 sections that contain 5 or more numbers. Work through the remaining empty cells, trying the numbers that have not been used. In many cases, you will find numbers that can only be placed in one position considering the other numbers that are already in its row, column, and 3×3 grid. Arrows provide lots of information that helps you to solve the puzzle. 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.

In addition to the standard Sudoku rules of every row, column, and 3×3 region containing the numbers 1 to 9 once and only once each, Arrow Sudoku only has one additional rule. 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. 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'. 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.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.
