@Hasenvogel:
It's a bit late, but I saw your comment first today. Do you still have your solution, so I can have a look at it?

bin mir sicher, eine richtige Lösung zu haben, der Code wird aber nicht akzeptiert. Offensichtlich gibt es mehrere richtige Lösungen.
Ansonsten aber ein sehr schönes Rätsel.

The first half is great the second half still good. It just gets too fiddly for my taste ;-). Still a "sehr gut" from me.

Schön langsam Zahl für Zahl ging es vorwärts. Vielen Dank, Richard! I am looking forward to your Jubiläumsrätsel :-)

Oh, oh. Den Hut bitte wieder zurück. Ich hab's zwar ohne EXCEL und ohne Fallunterscheidungen gelöst, aber nicht erst gestern begonnen, sondern schon vorm Wochenende.

Mit Hilfe von Excel ist das Rätel wunderschön und gut zu lösen, wenn man bei der Suche nach beispielsweise den Dreien mit einer Farbe die Zellen markiert, in denen keine "3" stehen kann. Die Farben helfen dabei, die "unmöglichen" Zellen in beiden Diagrammen im Auge zu behalten.
Hut ab vor unserem Chälbli, der das in der kurzen Flugzeit ohne Excel fertiggebracht hat :)

Well, at least I had a good home-trip. And this is to a great part due to finishing this fine one during the flight from SB to HH.

Hi Richard! Very very nice, this one. Hope you had have a lot of good ideas during your home-trip from PS... :-)

yep, no T&E, but didn't solve it very speedily either. Good one, Richard!

on 22. October 2009, 15:49 by Luigi
Well... that was one of your real tough ones! Thanks a lot!

on 22. October 2009, 15:22 by zuzanina
I agree: No T&E needed. I liked it a lot! Thanx! :-)

You're right. It's not so hard and no try and error needed. I've enjoyd it very much.

Hmmm, if you work with your pencil marks and eliminations consequently in both grids and use the law of leftovers consequent in both grids, no T&E is necessary. Even the more common exotic moves like wings, chains and jellyfishes (or whatever they are called) don't have to be used...

Ouch... this was very hard... I think one of the hardest I ever solved. Needed lots... LOTS of trial and error...
Thanx Richard!
