@uvo: I guess you are right. In fact, this one was meant to be an introduction to the other one.

I think this puzzle type is much more interesting with several overlapping grids. This is probably the reason why Halbdominos 2 is rated much better.

I found this type very interesting in WPC, for the reason that 'digits' have different remarks, making it fun to play around with. With just 8 given digits I think it's a pretty nice puzzle, considering it's size and possibilities. But obviously, it is one of my worst rated puzzles, so I have learned something again. Thanks for all comments. :-)

Ich kenne eine Variante, bei der man die Halbdominos frei plazieren kann (das Gitter ist dann etwas größer). Die fand ich ganz gut. Hier ist man meines Erachtens doch stark eingeschränkt.

Ich finde den Rätseltyp nicht so ganz überzeugend. Letzen Endes waren alle Überlegungen "rein mathematisch" und fanden auf einem Extrablatt statt. Das Lösungsgitter hat mir überhaupt nicht geholfen.

Schöne Konstruktion zum Einstieg. Jetzt ist mir klar, warum uvo es im Finale gewählt hat und kein anderer es wollte.
