Play Sudoku Online - Billions of Free Puzzles for All Levels

Modern day Sudoku became popular in Japan in the 1980s, but its roots can be traced back to Switzerland in the 1700s. Mathematician Leonhard Euler created an idea called “Latin squares” – a grid of symbols in which every symbol occurs only once per row and column. This paved the way for modern day Sudoku.

And here we are in the late 20th century, when the American architect Howard Garns created the puzzle “Number Place” in the 1979s which is the closest resemblance we have to the modern-day Sudoku. However, the real charm of the puzzle emerged from Japan. A Japanese puzzle company named Nikolai labeled it as Sudoku, wherein he made betterment by ensuring that each 3x3 sub grid contains separate digits. The puzzle gained worldwide appeal in the early 2000’s due to it being introduced in newspapers, alongside the introduction of online puzzle sites.

Rules of the Sudoku Game

Although the rules of Sudoku may seem trivial, they are in fact a leading cause to rewarding and complex gameplay:

• The Grid: A standard sudoku puzzle is assembled on a nine by nine grid, which is divided into nine three by three grids.
• The Goal: The grid needs to be filled in such a manner where every row, column and the three by three container has the digits from one to nine.
• Starting Clues: A puzzle is solved by commencing with clues or the digits that have already been placed in the grid.
• Logic Over Guessing: Each digit requires its place to be filled logically, therefore guessing is a flawed approach.

While these rules may appear as basic for the novice solver, learning to master the details of the logical deduction will differ in importance as the puzzles become more sophisticated.

Beginner Strategies

To defeat Sudoku puzzles, here are some Sudoku beginner strategies that will help you win:

• Start with the Simple Puzzles First: Always start with puzzles which are simple or will help you understand the basic mechanics of the game and how not to lose.
• Look for the Obvious Numbers First: Try and search through the rows, columns, and subgrids and scan for any numbers that can fit in just a single place.
• Use the Elimination Method: Start searching for numbers that just cannot fit in a specific cell.
• Stay Organized: Attempt to concentrate on one row, column, or subgrid at a time in order to tackle the entire puzzle.

You will get an inherent sense of where the numbers are placed while dealing with more complex puzzles as you hike practice.

Intermediate Techniques

Once you have mastered the fundamentals, these intermediate techniques will help you be able to solve harder puzzles:

Pencil Marking: Lightly write numbers that you think might go in every empty cell. This will help you keep track of potential candidates.

Naked Pairs and Triples: Naked pairs or naked triples consist of groups of two or three numbers which can only exist in a single row, column, or subgrid. Therefore, they can be removed from other cell options.

Block and Column Interactions: The interrelation of a row, column, and subgrid can be used to remove numbers from some particular cells. For example, if a number is restricted within a row to a particular subgrid, it cannot be present in the row, outside of the subgrid.

Scanning for Patterns: Scan for primary structures of columns or rows where there are not many options for particular numbers.

Like all other techniques, these require practice and patience but are vital for engaging in puzzles with less starting clues.

Advanced Tactics

Having come to know more challenging approaches to monitoring Sudoku maps, it’s apparent I haven’t yet gained the technique. One of them is an intercrossing pattern.

X-Wing: It involves two intersections of columns being filled in while candidates for any boxes which touch the other two patterns must also intercross on two other boxes. These rows (or columns) must have the designated row/column erased or the opposite box hidden.

Swordfish: A further complicated version of the X-Wing, this method expands to estimating 3 rows (or columns) and it works by spotting patterns throughout different rows or columns.

Hidden Pairs and Triples: Unlike the naked type, hidden pairs are the circumstances in which two numbers are hidden in other options but in specific cells, they can only be the two candidates useful.

Forcing Chains: An advanced logical technique to place the candidate, then check if the placement of a determined number leads to a contradiction.

Coloring: Use color or mark the candidate numbers to find patterns that could eliminate the complexity of the puzzle.

These strategies take a great knowledge of Sudoku and sometimes learning the methods may involve trial and error. Yet, perfecting each tactic elevates one into a Sudoku expert.
