Jubiläumsrätsel - 4 Jahre Rätselportal

(Published on 1. November 2012, 00:00 by Richard)

Today the puzzle portal celebrates its 4th anniversary! For this occasion I prepared a special 4X-sums-sudoku. Enjoy!

4X-sums-sudoku
In all four puzzles the digits from 1 to 7 have to be placed in every row, column and boldly outlined irregular area. In the grid bottom left the digits from 1 to 7 have to be placed in the grey cells once also, and twice in the grid top right. In the grid bottom right some of the irregular grids wrap around the grid from left to right and/or from top to bottom.

X-sums
Numbers between the grids indicate the sum of the first X digits in one of the two possible directions. X is the first digit in the corresponding direction. Every clues is valid for exactly one direction. You have to find out yourself which clue is valid for which direction (left or right/ up or down). An easy example of a plain X-sums-sudoku can be found here.

Solution code: Column 4 (top left), column 3 (top right), column 2 (bottom left), column 1 (bottom right).

Wow, dieses Rätsel ist ja wirklich ein Kunstwerk. Kein Wunder, dass ich es in der "Liste der schönsten Rätsel, die Sie noch nicht gelöst haben" gefunden habe.

Ein klassisches Richard-Rätsel, wie ich es liebe: Es geht immer wieder ein Stückchen vorwärts - und dann braucht es eine Pause, damit es sich setzen und nachwirken kann. :-)
Danke, lieber Richard, für bisher 277 wundervolle Rätsel!!!

Tolle Konstruktion. Wenn man erst den Einstieg gefunden hat, läuft´s ganz logisch und eindeutig durch. Sehr schön.

Dear Richard, was wäre das Portal ohne Deine Rätsel, ohne die schon zur absoluten Routine gewordenen Freitag Mittag Snacks?
Vier Jahre Rätselportal sind auch 4 Jahre Richard!
