Here are some helpful Sudoku tips
Sudoku Tips – Sudoku is a popular number game and is a logic-based, combinatorial number-placement puzzle.
This game was introduced to the public in 1979. Each puzzle has a two-dimensional grid of nine rows and nine columns. The goal of the player is to fill all 81 cells with a number from one through nine, subject to two caveats.
For some people, this game is just a piece of cake while for some it is not their cup of tea. For those who want to be an expert in this game, here are some tips you should follow, based on the article in Reader’s Digest.
First, you need to familiarize yourself with the terms and the candidates.
Don’t use “automatic candidates”
It can be difficult to see even simple patterns within the Sudoku grid when every cell has lots and lots of markings in it.
Don’t guess
When you guess, it avoids finding the logic that most Sudoku puzzles possess. A legitimate or “fair” Sudoku grid does not require guessing at all.
Some candidates will be obvious at the start
Because of some placement of givens, it will tell you that only one candidate is possible. The best way to do this is to start your Sudoku-solving by seeking out this “low-hanging fruit” in the rows, columns, and squares that contain the greatest number of givens.
Take the “square route”
Probably the most common tip is to focus on what is referred to as “chutes” of three adjacent nine-by-nine squares, and they occur both vertically and horizontally. You can follow the “three number rule” or “a digit must appear three times per chute but only once per row, column, and box.” In doing this tip, you should scan rows or columns within the chute that already have two of the same digit.
Make use of “pencil-marking”
You can break out the “pencil-marking” strategy after identifying a number that can fit into two or even three possible cells in one house.
Practice and practice some more
Getting that certain expertise in anything, practice plays a vital role and this is also applicable in playing sudoku.
