X-diamonds (meagre yield)

Postby m_b_metcalf » Thu Jan 09, 2020 3:38 pm

As mentioned already in another topic, I have attempted to generate some X-sudoku diamonds, but with limited success, as shown:

Code: Select all
 . . . . . . . . .
 . . . . 1 . . . 2
 . . 3 2 . 4 . . .
 . . 4 . . . . . .

 . . . . . . 3 . .
 . . 5 8 . 2 1 7 .
 8 . . . 6 . . . .
 . . . . . . . . .   ED=2.9/2.9/2.9  X

 . . . . . . . . .
 . . . . 1 . . . 2

 . . . . . . . . .   ED=4.3/4.3/4.3  X

 . . . . . . . . .

 . . . . . . . . .   ED=7.7/7.7/7.7  X

 . . 1 . . . 2 . .

 . . . . 7 2 . . .
 . . . . 6 . . . .
 . 7 . . . 8 . 9 .   ED=7.8/7.8/7.8  X


Maybe someone else will have better luck.

Hidden below is a selection of not-too-difficult X-puzzles for anyone tempted to try them.
