Ha, I didn't planned it but it so happens that I solved this puzzle on its 10th anniversary. :)

I still remember the first WSPC I visited in Kroatia very well, and that was also the first time I came across this type. Brings back memories! :-)

Puh, war das eine schwere Geburt! Ich hatte mich mehrmals in Wickelsprüche verwidert... :-)
- beim Wegschmeißen der falschen Versionen habe ich gesehen, dass im 1. Versuch bis auf einen Zahlendreher alles gestimmt hatte... Gna, gna, gna.

Vielen Dank, Richard!

@Luigi: have a good weekend too! It was not my intention to make either one of the two half dominoes a hard puzzle. I felt more like investigating the possibilities this puzzle type offers and the interdepending relations between the overlapping grids.

Der ist mir fast leichter als sein Vorgänger gefallen!
Ein schönes Wochenende, Richard!
