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!
