- "Diagonal Sudoku" or Sudoku X;

- Killer Sudoku ("Sums Number Place"): sub-regions have specified sums, and no number can be repeated within a region;
- Greater Than Sudoku;
- Even-Odd Sudoku: white cells must contain odd digits, gray cells must contain even digits;
- Flower Sudoku;
- Consecutive Sudoku ("1-away Disallowed Number Place"): all the places where orthogonally adjacent cells are consecutive numbers have been specially marked;
- kakuro.

The program solves sudokus without any human participation (i.e. no manual mode).

Also "Cross+A" allows to generate some kinds of sudokus:

- 9x9;
- 10x10;
- 12x12;
- 16x16;
- "Diagonal Sudoku";
- "Geometry Sudoku";

- Greater Than Sudoku;
- Even-Odd Sudoku.

The generated sudoku has only one possible solution.

Hm, thanks for the task with empty central grid 9x9... Shocked

Yes, the program begins to solve Kazaguruma from the central grid now. In next version we will analyze other grids also and after that choose the appropriate grid to start the solving.

If Cross+A will start from the left-upper grid, this Kazaguruma will be solved during 3-4 minutes (P4 3000 MHz).
