Portal Sum - Little Killer Sudoku
(Eingestellt am 22. April 2022, 16:46 Uhr von Playmaker6174)
- Normal Sudoku rules apply: every row, column and 3x3 box contains digits from 1 to 9 each once.
- The oval shapes in the grid are called "portals". Portals of the same color must contain the same digit and work as a pair of entry-exit points for little killer clues.
- Little killer: an outside clue shows the sum of the digits in the cells along the indicated diagonal; digits can repeat if allowed by other rules. The limit a little killer clue can reach to is 9x9 border.
However, if a little killer clue points to a portal, that clue is instead the sum of the digits before entering the portal PLUS the digits after exiting the paired portal in the same direction, NOT including the digits in the portals themselves.
- Inequality sign: R2C2 is greater than R2C1.
To demonstrate how a LK clue entering a portal works, in the following example: 20 clue is the sum of all digits in the yellow cells; 15 clue is the sum of all digits in the purple cells (regular little killer clue).
Good luck and have fun solving!
Lösungscode: Row 8 (left to right) and column 3 (top to bottom), 18 digits long with no space

This is not a 4. This is not a 4. Ok... maybe it is a 4. Yes....it is certainly a 4. Definitely a 4. Very nice!

Now you're setting with portals!

Wonderful puzzle. Love the concept for the portals and how it can change up the LK constraint.
Beautiful logic for the break-in, and then chasing colors the entire way around the grid.

Very nice! I really enjoyed the interplay of boxes 2,6 and 8 in this one! The later stages felt comparatively hard, even though it all came together nicely at the end. Fun concept, I would like to see more of this variant! :^)

Thinking with portals doesn't help, what one needs is scanning.
And colors. :P
