What is a Sudoku solver?
Sudoku is a number crossword puzzle that has become the talk of the town because of its addictive nature. At first sight, it is only a grid to be filled in with numbers but when one dwells further on the game, it becomes so challenging that it is impossible to put it aside without finding the solution. The mystery behind finding the solution to a Sudoku grid is to not repeat any numbers and plug them in to make the sum of each sub grid the same.
Seemingly easy to apply, this rule becomes a big obstacle when you feel the numbers ‘attacking’ you from right, left and center! Some help at this time is very necessary so that you can find your way past the hurdles. Even though, for some people the thrill of Sudoku is best felt when they solve it without any hints, most players take help from Sudoku solvers that can give assistance every time you feel there is a bottleneck. Sudoku solver is like your guide through the maze of the numeric crossword. When you play Sudoku online, the Sudoku solver gives hints, highlights blocks to be filled and keeps a tab on the numbers that should be used.
Is Sudoku too difficult for you? Try a Sudoku solver
Sudoku comes in varying levels of complexity. Easy, medium, hard, evil and extreme are some of the very popular ones, however, levels that are a cross between the above mentioned have also been created. Even if you have played and gone beyond the easy and medium levels, you will need assistance at some point because the higher levels are so complex that even Sudoku experts feel challenged.
In the crudest sense, when you are using a Sudoku solver to aid you in the puzzle, you are in effect using a computer program/software that has been designed to read the puzzle, apply a technique and solve it in the blink of an eye. At first, these programs were meant for puzzle developers who needed the solution to the puzzles they created. However, as the levels of difficulty grew with time, a Sudoku solver became a great way to check for the right solution so that puzzle lovers could learn techniques and figure solutions at the same time.
