An "X" means the value of a particular cage is unknown. In these cages also no digit can be repeated.
Each of the digits 1-9 does appear twice in the yellow marked cells.
A red dot means the difference between those two cells is 3. All dots are given.
Solution code: Row 5, followed by column 5

@ all puzzlers:
I changed some cages because I was a bit careless while filling up the diagram with "X-cages". It's repaired right now... sorry for that!

@ all puzzlers:
Thanks to pin7guin and flaemmchen I discovered a "terrible" mistake... but I'm not able to repair it at this moment. Call it a bit uncareful... I will tell it all after I repaired it later today...

@ flaemmchen: Deine Annahme ist falsch. Auch in diese Gebiete dürfen Ziffern nicht doppelt vorkommen.
Aber: ich denke du hast recht. Meine Beschreibung war vielleicht nicht ganz deutlich :-) So ich habe meine Beschreibung etwas geändert, ich denke es ist völlig jetzt. Danke flaemmchen!
