Also known as Number Place, this is the puzzle that has become a world-wide phenomenon. NumberPuzzles.com has been offering these puzzles since 2002, and is very pleased to see the rest of the world catching on!

Our puzzles are carefully graded by difficulty: Easy, Moderate, Hard and Challenging. (We can also generate Extra Easy puzzles that are suitable for younger solvers.) All puzzles are rigorously tested to ensure that they have exactly one solution, which can be deduced by logic alone (no guessing is required.)

We provide puzzles and solutions in print-ready format (EPS, or Encapsulated Post-Script) as well as machine-readable format (XML), and can provide custom content and format as required.

We also support a number of Sudoku variants: (Click link for more details.)

Sudoku-X: The diagonals must also contain 1 through 9 exactly once.

Sudoku-6: A 6x6 puzzle that is fast and fun to solve!

Killer Sudoku: Samunamupure, or what we call Fusion!

Please feel free to download our samples or contact us with your requirements.

You can find our puzzles at universaluclick.com and in Edigrama publications.
