Place the digits 1 to 9 in every row, column and 3x3 standard block. Each diagonal must contain only 3 different numbers (e.g. 2,3,6 or 1,5,7 etc.). Besides grey painted cells form renban groups. These groups must hold consecutive numbers, in any order.
Lösungscode: First give the five digits on the two main diagonals increasingly; then give the contents of column 3, followed by row 6.

Thank´s for this great puzzle and for all the others you´ve created. I guess, it must have been a lot of work :-)
@suse: Thanks for your kind words. And your guess is true it is really tiring but also satisfactory process to publish a puzzle. It needs design period and also testing period for uniqueness and some other points. I wish the number of puzzle authors supplying different puzzles for portal will increase in time. There are so many good puzzlers in the portal and I'm sure that most of them have different and fascinating puzzle ideas. I hope they decide to publish these ideas and share them with us.
