Different Types and Variants of Sudoku

Are you looking for a way to solve sudoku? If so, then you have come to the right place! This blog post will go in depth into how to complete this puzzle. We will talk about tips and tricks that can make it easier on yourself when solving this puzzle. Along with these tips, we will provide an example of each tip in action. So without further ado, let’s get started!

What is Sudoku

Sudoku is a puzzle that has nine small squares on each of the puzzles called “boxes” or “regions.” The goal of sudoku is to fill in every square with digits so that no digit appears more than once in any row, column, and region.

You can do this by solving some simple math equations such as: ‘a times two plus b equals six’ for example.

Tips to solve Sudoku

There are many strategies for solving Sudokus which will be discussed below! If you want to learn how to solve these tricky little puzzles then read on for all the tips and tricks you need!

  • Work on Sudoku puzzles in a grid order. This is the best way to find patterns and if you have been working on it for too long, switch your perspective by thinking about solving rightmost column first or left most row first instead of going from top to bottom.
  • The easiest place to start looking for numbers is diagonally across the puzzle (from opposite corners). It takes less time than trying every possible number combination within one square.-When analyzing each pattern of squares, make sure that there are three times as many candidates in an area before moving onto another region because this will help eliminate wrong choices quickly.
  • Use strategies like crossing off digits when they appear twice or using trial and error where you try different numbers until the correct solution appears.
  • The best way to solve a sudoku is by getting the side of the puzzle done first, then filling in from there.

Types of Sudoku

Normal sudoku comes in 3 types:

-Easy: very few that are diagonally across the puzzle, and most of them have only one or two candidates. The solving process is quick here as well because there are so many possible combinations. For example, 4×4 grid sudoku.

-Medium: this type has a lot more numbers on the outside in addition to some inside squares; short lists for each square with multiple candidates helps eliminate wrong choices quickly. For example, 9×9 grid sudoku.

-Difficult: these puzzles require time management skills where you need to look at all of the information given and make use of different strategies simultaneously. For example, 20×20 grid sudoku or a variant like word sudoku.

Variants of Sudoku

  • Wordoku (Letter Sudoku) – These puzzles have letters filling in the grid instead of numbers.
  • Diabolik – These are puzzles made up of a diagonal row from left to right and another one that is vertical. This variant is more difficult because there are two rows with only one or two possible combinations for most squares, so it takes longer to solve them than regular sudoku.
  • Killer Sudoku – Killer Sudoku puzzles have a darker background and allow for more than one solution. This is the perfect puzzle to keep in your pocket when you’re on-the-go because it doesn’t take long to solve, but at first glance there appears to be two or three solutions which makes them challenging puzzles to complete.
  • Samurai Sudoku – Samurai Sudoku is a variant of the traditional Japanese puzzle where there are three possible solutions for each square.
  • Diagonal Sudoku – In this variation, a row or column is filled with numbers while the rest of the board remains blank. The object is to solve all rows and columns before filling any other squares on that particular row or column.
