What is jellyfish sudoku?

It is a type of sudoku puzzle in which the numbers 1 through 9 are placed in a grid, like a regular sudoku puzzle.

However, in jellyfish sudoku, some of the squares in the grid contain more than one number.

In other words, jellyfish sudoku is like a regular Sudoku puzzle with some of the squares filled in already.

The game is played with a 9×9 grid, in a standard sudoku arrangement.

The only difference between jellyfish sudoku and regular sudoku is that there are three possible places to put each digit instead of just one.

So each puzzle will have 3 different solutions (hence jellyfish) since all digits 1-9 must appear once in each row, column, and 3×3 box (the sea).

For example

If you had to choose which out of these three would be your next move: 1 2 6 5 or 8 7 4 9?

In normal sudoku, there would only be one choice: #1 2 6 5 because digit #8 can’t go anywhere else other than where it already is.

Jellyfish Sudoku is a traditional Sudoku puzzle with one major twist

Instead of using the standard puzzle rules, you must find the correct placement of numbers in each row, column, and 3 x 3 box without repeating any numbers and without having two jellyfish touch each other vertically or horizontally.

This challenging puzzle will test your sudoku skills like never before!

How to play jellyfish sudoku?

There are a few things you need to know to play jellyfish sudoku.

  • Jellyfish sudoku Need 4 Cover and 4 base Numbers.
  • There is only one solution to each puzzle.
  • The goal is to fill in the grid so that every column and row contains a unique number.
  • The numbers in the grid indicate how many unique Digits are in that row or column.
  • Next, mark each square in a jellyfish sudoku puzzle with a number between 1 and 9.
  • Next, fill in every other cell by marking off numbers such that:
  1. Each row and column contains exactly one instance of each number.
  2. The number of instances of each number is equal to its row or column value.

There are a few ways to play jellyfish sudoku.

  • One way is to fill in the numbers 1-9 in each column, row, and 3×3 grid so that no number appears more than once in any row, column or grid.
  • Another way to play is to fill in the numbers 1-9 so that they appear only once in each row, column and grid, but not necessarily in the same order as the first way.
  • For example: if you fill up a 3×3 square with numbers such that every number appears once and only once, that would be 9. But to call it a jellyfish sudoku puzzle, you also have to consider two diagonal lines of cells in addition to every single row and column of numbers. So you can’t have any multiple of three appearing anywhere inside a 3×3 box—not even on diagonals!

Rules for Playing Sudoku Jelly Fish

To start, solve a standard 9×9 sudoku puzzle.

Once you’ve got your solution, transfer any number from that grid to a corresponding position in a jellyfish grid.

Make sure you keep all of your columns and rows consistent as you move numbers around.

For example

If there are five numbers in one row of your original sudoku puzzle, make sure there are also five numbers across in your jellyfish sudoku puzzle.

If a cell has an X marked on it for containing an invalid number, cross out that X and mark it with a big circle; in future steps, these circles will complete Sudoku Puzzle.

While there is no one definitive way to play jellyfish sudoku.

However, there are a few general tips that can help you improve your chances of success.

  • First and foremost, always start by filling in the easy squares. This will give you a foundation on which to build and will help you avoid getting stuck later on.
  • Secondly, make sure to use the jellyfish numbers strategically. These numbers can help you break difficult puzzles open, and should be used whenever possible.
  • Finally, remember to use your intuition. If something doesn’t seem to fit, it probably isn’t right –

The objective of Jelly Fish Sudoku

The objective of regular sudoku is to fill in all of its empty cells using only the numbers 1 through 9, once for each row, column, and 3×3 region.

Similarly, in jellyfish sudoku, each jelly cell must be filled in based on its own set of rules.

In addition to that, no two adjacent cells can have consecutive numbers (i.e., 2-3 or 5-6).

As with regular sudokus, that alone is challenging enough; however, there’s one more little twist: some squares cannot contain any numbers at all!

How many different ways to play jellyfish sudoku

Jellyfish sudoku is an 11×11 sudoku puzzle that uses only 4s and 9s.

In a standard 9×9 puzzle, there are 81 squares (8 of which contain only 0s). But in jellyfish sudoku, there are 121 different squares used.

That’s about 18 million possible combinations for a single jellyfish sudoku puzzle!

If you can complete one of these puzzles without using any pencil marks or guessing, then you’re on your way to being crowned king or queen of logic puzzles.

There are many different ways to play jellyfish sudoku. There may be an infinite number of ways, but here are a few of the most common ways:

  • One way to play jellyfish sudoku is to fill in the numbers one through nine in the grid so that each number appears only once in each row and column.
  • Another way to play jellyfish sudoku is to fill in the numbers one through nine in the grid so that each number appears only once in each 3×3 square.
  • Another way to play this advanced sudoku strategy is to use the numbers 1-9 in each row and column, but only use the numbers 1-6 in each 3×3 box. This is called a 6-j

The different types of jellyfish sudoku

It’s also worth knowing there are two types of jellyfish sudoku: single jellyfish and multiple jellyfish.

In single jellyfish or Simple Jellyfish Sudoku, you’ll have a grid with some numbers filled in and some missing—kind of like a normal Sudoku puzzle with one added twist: That twist is that one particular square must contain exactly one or two numbers.

On the other side in Multiple Jellyfish or Ghant Jellyfish Sudoku, it’s not a normal-looking puzzle that is missing one value for every row and the Square contains a lot of values that confuse the solver, column, and (in multiple) 3×3 box.

That’s why in multiple jellyfish puzzles, all squares must contain five (or more) digits.

The key to solving jellyfish sudoku is to identify the possible pairs of numbers that can be placed in the squares.

In the 3×3 grid, for example, there are six squares in total.

This means that six different pairs of numbers can be placed in the squares.

Tips for beginners

The most important thing to remember when solving jellyfish sudoku is to:

  • Start with the easy squares. This will help you to get a foothold on the puzzle and work your way up to the more difficult squares.
  • Another helpful hint is to focus on the numbers in the corners of each square. These numbers are often the easiest to solve because they are surrounded by other numbers that are relatively easy to deduce.
  • Finally, don’t be afraid to use pencil marks to help you keep track of which numbers have been used and which ones haven’t.

Advanced strategies for playing jellyfish sudoku

There are a few different techniques that can be used when playing jellyfish sudoku.

  • One advanced strategy is to try and eliminate as many of the jellyfish squares as possible in the early stages of the game. This can be done by looking for patterns and using logic to determine which squares can’t possibly contain a2, 3 Numbers.
  • Another strategy is to use the “jellyfish chains” technique. This involves tracing all of the possible chains that could lead to a particular Numbers Series and then eliminating all of the squares that don’t contain a link in the chain.
  • These are the squares that contain two numbers, and they can be hard to solve because you have to guess which of the two numbers is correct
