In the mentioned question, you would have to write an algorithm that applied the concepts of recursive programming and backtracking to solve a sudoku game. You will notice that many of the squares have multiple potential values, while some are completely solved. This grid above is the result of rote application of the two strategies from above. But as you can see, those strategies alone are not enough to completely solve the puzzle. In the example below, the possible numbers for each square are noted in a smaller font.

  • But you may want to learn more about the different strategies involved in solving harder puzzles.
  • For example, say you have a horizontal row with 3 blank boxes and the clue is 22.
  • You may also need to refer to tutorials or use hints frequently.
  • So, if you’re scanning for the number one, and you find a 1 in the set of three rows you’re scanning check your candidates in that square, row, and column.
  • You’ll see the apps you use and information about how much battery each is using, plus how much time the app spends running in the background.
  • But then the two ends of the hinge would be X, and that would remove all possibilities for X in Row 2.

If a grid of cells can be made for which the value in one cell directly forces the value in another cell, we can sometimes follow that grid to see if it leads to a logical inconsistency. This can be done even though the exact contents of a cell are unknown. Some algorithms look for „strong cycles” with „weak edges,” but there is another way to think about this. What is significant is that in a „binary grid” every other cell along the grid either has one value or another — only two possible values. A 5×5 circuit containing the candidate number „1” hiding in a simple Sudoku.

After this the remaining puzzle can be solved by spotting singles. Once again highlighting the columns, you know that you can remove candidates for 4 from anywhere in those columns other than the three Swordfish rows. This is very similar to using X-Wings, in that it will allow you to use knowledge about rows to remove candidates from columns, and vice versa. Additionally, I just want to point out that there are many ways to solve Sudoku puzzles and that some of the possible techniques that can be employed were not mentioned above. I didn’t mention them because I didn’t need them when solving the puzzle we looked at together. Also, just to let you know, in the images I use, I am going to number the rows and columns from 1 – 9.

In practice you’ll soon find that you stop working in passes through the whole puzzle, and begin darting to whichever area looks most likely to have solvable squares. The stack of boxes starts out with just one 7 in place . This solves the middle box’s 7 , and entering that immediately solves the top box’s 7 as well. This uses a technique called 'crosshatching’, which only takes a couple of minutes to learn. It can solve many 'easy’ rated puzzles on its own.
