Quick Help:

  • Charset defines used characters. First character is for unsolved cells.
  • When no charset is given, default one is used (i.e 0123456789ABCDEF...).
  • Characters that are not present in charset will be ignored.
  • Region map indicates regions in the puzzle. Use all but last character in charset.
  • When no map is given, each region is assumed identical (e.g. 1x1, 2x2, 3x3, etc.).
  • Grids with sizes other than 1x1, 4x4, 9x9, 16x16, etc. must have a region map.
  • Default values for advanced options are fine for almost any sudoku puzzle.
