Doppelstern, selbstklebend
(Published on 19. October 2012, 02:08 by uvo)
Place stars into the grid, so that each row, each column and each outlined area contains exactly two stars. The stars have the size of one cell and may not touch each other, not even diagonally. Marked cells may not contain stars.
That's not possible, you say? Well, the puzzle is not finished yet.
Do you know how to create a cylinder from a rectangular sheet of paper? Simply glue two opposing edges together. Or a Möbius strip: in the same way, but twist the edges before glueing them.
In this way, several other geometrical objects can be created. And this is exactly what you have to do here: The puzzle has four edges. Glue them together in pairs (twice glueing two edges). What edges shall be glued together and whether to twist them is for you to decide. By the way, these operations may not actually be feasible on a sheet of paper in three dimensional space.
Since the terms "row" and "column" may lose some of their meaning, here is a new definition: Start in any cell and go into any direction until you reach the starting cell from the opposite direction. The set of cells you encountered on your path is called a row; every such row must contain exactly two (different) stars.
Ignore numbers and letters outside the grid, they act as coordinates only.

Manchmal freue ich mich im Nachhinein, dass mir beim Lösen keiner zugeschaut hat. ;-)
Tolles Rätsel und gar nicht soooo... schwer.

Wie konnte ich nur soo lange immer auf dem gleichen Schlauch stehen...

Das war Spitze! Auch wenn ich mich dreimal in den Widerspruch verspielt habe. Ich sollte einfach die Anleitung nicht zu schnell beiseite legen oder wenigstens richtig lesen.

Thanks for the original puzzle!
