Sudoku advanced strategies
As mentioned above, there are plenty of advanced Sudoku strategies that players can use to successfully solve their Sudoku puzzles. However, when it comes to Sudoku strategies, the best strategy is going to be the one you understand and makes sense to you. If you find a certain strategy not working for you, you can always hop onto the next one to solve your puzzle. Here are some of the top advanced Sudoku strategies.
The X-Wing Strategy
The X-Wing method is one of the most basic advanced Sudoku strategies. However, it is also worth mentioning that this strategy can also be applied in certain intermediate levels, though its incidence is quite low in these cases.
For this strategy, the player will be looking at the parallel rows and columns. The player won’t be concentrating on squares that much. The goal of this strategy is to eliminate possible numbers and remove some of the pencil marks you made when starting the game.
Look at the rows to see if there are any pencil marks that are precisely the same in two spots. Then match that row with another row that is parallel to it. Remember that the pencil marks should be exactly the same in the two spots.
This strategy requires plenty of thinking, but it is very effective. It is not ideal for beginners. However, if you are looking to improve your skills, it is a perfect option. It will definitely help you develop the skills needed to move from just focusing on one row, one column, or one square. The X-Wing strategy can help you see the bigger picture.
The Swordfish Strategy
This strategy is also almost similar to the X-Wing strategy since it also helps to eliminate a candidate from the cells as well. The only difference is that in this strategy, you are looking at 3 possible numbers in 3 rows or columns, and not 2 possible numbers in two rows which is the case with the X-Wing strategy. Without a doubt, it is an advanced strategy. If you have not yet understood the X-Wing strategy yet, you are more likely to find Swordfish strategy very frustrating.
To apply this strategy, you need to find a number candidate to 2 cells in the similar row in 3 different rows. The cells should also be joined by columns despite the shape created by them. Linking them will lead to a closed chain that discloses two sets of possible placements for that number you can then put them to the test and get rid of that digit as a candidate to the cells where it becomes impossible in both cases.
It is worth mentioning that the Swordfish strategy is a highly advanced and somehow a complicated strategy you can use to solve your puzzle. It is best suited for Sudoku fans that have been playing Sudoku for a very long time and so they understand how grid patterns work. If you are someone who is just getting started with Sudoku, this strategy may not be suitable for you because you will likely be unable to see the patterns, making you fail to solve that particular puzzle. You may try using the X-Wing strategy as it is beginner-friendly.
The forcing Chains
This strategy is one of the advanced Sudoku strategies that are easy to understand. However, applying it can be very challenging. That’s because it requires a high level of concentration and outcome can be unsure. When it does work, it will give the player the solution for one cell.
To apply this advanced Sudoku strategy, there must be cells with just two digits in the grid. You pick one and begin testing the changes to the puzzle when applying all of the two digits in that cell. The objective of this strategy is to find if there is a cell that can bear the same result regardless of the digit used. If that is the case, that will be the solution for it.
There you have it; some of the best advanced Sudoku strategies for success! These strategies can help you get your puzzle solved successfully. Moreover, they can help you become a pro-puzzler.
