Sudoku puzzle maker
If you want to publish a new Sudoku easily and in a fun way, then this sudoku puzzle builder is the one for you.
Start with the basic grid and go from there to make it feel like your own by tweaking the different types of settings.
Create a custom Sudoku for your own platform by changing the colors, number entries, size and difficulty in just a few clicks.
Choose the size of your puzzle grid
Depending on your audience you might want to tweak the size of the Sudoku grid to a higher or lower value than the default 3x3.
Interesting 'easy' options are the 2x2 and 2x3, while the more hardcore Sudoku players might prefer the 3x4 and 4x4 size.
Create a custom Sudoku
The coolest and unique feature of this Sudoku puzzle maker is the ability to change the default numbers to any type of content you like by enabling 'with media'.
This way you can turn any number into an image, description or even audio file! Turn the number 5 into the logo of your organisation for example and you have a branded Sudoku with a unique experience!
Adjust the difficulty level
Besides the size of the grid, you can also adjust how many 'helper' cells are shown, cells that are pre-filled with the correct number.
This way you can control the difficulty of your Sudoku puzzle a bit, tweaking it to the level of your players.
Players can take notes
Just like in the offline Sudoku puzzles, you are able to add notes to empty cells to keep track of what number options are possible there.
This way the harder Sudoku puzzles are easier to solve, or at least, more clear and full of reminders for the players.
Organise a Sudoku battle!
Since Puzzel.org has cool multiplayer features by default, you might want to enable the option to allow players to challenge each other.
A fresh Sudoku puzzle is very well suited for a challenge and even more fun to solve when racing against the wits of another player!
