This is a smaller variety of Sudoku X that uses digits 1 through 6 on a 6x6 grid of 2x3 zones. Each shaded diagonal must contain each digit exactly once. The intense interation between the diagonals and the other contraints permits breath-takingly few givens to start. Solvers find this variation fast, fun and refreshing.

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.
