--- Comment #4 from Ian Wadham <iandw...@gmail.com> --- In the attachment I added, line 2 as 1243 is invalid because it has two 2's in the top left 2x2 grid and two 4's in the top right 2x2 grid, whereas 1423 in line 2 leaves one occurrence of the four possible digits in each grid. A similar requirement applies to line 4, in which 3241 is the correct and only solution. This rule is the same as in the Classic Sudoku 4x4 puzzle. My apologies if the 2x2 grids are not shown clearly, but I inherited the existing graphics when I implemented the Killer Sudoku and Tiny Killer puzzle types and their generator. in the Mathdoku (or Kenken TM) puzzles, there are no internal NxN grids and the cages can contain the same digit more than once. -- You are receiving this mail because: You are watching all bug changes.
