Siamese Rundweg Sudoku Twins

(Published on 2. December 2010, 21:35 by pokerke)

Even more rare than Rundweg Sudoku Twins, are Siamese Rundweg Sudoku Twins. They are cojoined side by side, and they cannot be separated because they form one traditional Rundweg together (with the given clues, 16x8 grid). Further, they are both separately 4x4 Sudokus (in the large cells containing 4 Rundweg cells each) with the numbers 1 to 4 in every row and column (not necessarily in each quadrant of the puzzle).

For the left twin, the sudoku numbers are equal to how many of the 4 rundweg cells are INSIDE the Rundweg.

For the right twin, the sudoku numbers are equal to how many of the 4 rundweg cells are OUTSIDE the Rundweg.

Solution code: The size of the areas outside the Rundweg, clockwise starting in the top left.

I was very surprised when I broke this puzzle to find out upon a closer reading of the rules that 'Siamese Rundweg Sudoku Twins' are not, in fact, sudokus ;)

Very nice, and fun both attempts!

Ist mir seltsamerweise schwerer gefallen als die 6x6 Variante ... aber insgesamt eine sehr interessante Familie :-))
Vielen Dank!

German description clarified as in Micha's comment below. The English text already had the clarification from the start, but it was forgotten in the German text.

Schönes Rätsel.

Mach vielleicht in den Regeln noch etwas deutlicher, dass in den Sudokus die Sudokubedingung nur für die Zeilen und Spalten gilt, aber nicht für die vier 2x2-Quadrate. Das steht zwar schon in den Regeln, war mir aber anfangs nicht völlig klar.
