Upload formats
Learn the different ways in which you can upload puzzle files.
PuzzleMe supports uploading Sudoku puzzles in XML, JPZ, and TXT formats. These formats are often generated by puzzle creation software.
- Supported Formats:
.xml
,.jpz
, and.txt
(including.sudoku.txt
and.sudokux.txt
). - Software Compatibility: These formats are compatible with popular puzzle creation tools such as Crossword Compiler (supports various grid-based puzzles including crosswords, sudokus, word searches, and codewords).
- Sample Files: Sample files in these formats are available on the PuzzleMe upload page for your reference.
Note that some word processors such as MS Word may save your text with formatting that renders it unusable by the PuzzleMe Dashboard. For this reason, we advise that you use software such as Notepad for creating TXT files.
TXT

You can upload TXT files with the following extensions:
.sudoku.txt
for standard Sudoku puzzles.sudokux.txt
for Sudoku X puzzles (with diagonal constraints)
Examples: name.sudoku.txt
or name.sudokux.txt

, to indicate that the user will have to figure out these slots.
You can use non-numeric characters as well, such as alphabets, emojis, etc.
Sudoku X
Sudoku X is a variant of Sudoku that includes an additional constraint: the two main diagonals must also contain each digit from 1 to N exactly once. When uploading a Sudoku X puzzle, use the .sudokux.txt
file extension. The data format follows the same structure as standard Sudoku puzzles, but the puzzle will enforce the diagonal constraints during gameplay.
Killer Sudoku
This puzzle can only be created using uploaded .json
files.
You cannot create a Killer Sudoku from scratch within PuzzleMe, although you can create a Sudoku puzzle.
Amuse Labs can provide a library of Killer Sudoku puzzles to users on the Enterprise Plan.
