Half Dominoes - one more time

(Published on 23. October 2012, 08:35 by rimodech)

Place all half dominoes in each of the nine 3x3-blocks in all five partly overlapping grids, so that every grid contains all half dominoes exactly once. The half dominoes may not be rotated or mirrored. Numbers outside the grid indicate the number of dots in the corresponding row/column/diagonal. Half dominoes may not repeat in any row or column and also not in two main diagonals. (A row/column contains all halfdominoes in the corresponding direction, no matter if there is an empty space in between)




Solution code: All digits in the first, third, fifth and seventh row (26 digits)

Although halfdominoes are definitely not my favorites I really like the concept of this puzzle.

Toll konstruiert. Keine Ahnung, warum ich mich immer wieder in Widersprüche verwickelt habe.

Die Sieben hat mir große Probleme bereitet. Ich bin es von meinen Domino-Steinen gewöhnt, dass der Punkt in der 2. Reihe in der Mitte ist. Immer wieder habe ich ihn auch dort eingzeichnet und bin dann natürlich auf Fehler gelaufen.
Abgesehen davon, finde ich diese Rätselart aber sehr schön.

A row (or column) contains all halfdominoes in the corresponding direction, no matter if there is an empty space in between.
So, the 9 in the last row is valid for all six halfdominoes, and no halfdomino may repeat in those six halfdominoes.

The 9 in the last row - is it valid for three or for six halfdominoes?
Do the last three rows count as one or as two halfdomino-rows? That is: Could halfdominoes repeat here - because I have two separated rows?
