This modification illustrates two methods for solving, not only the "cross hatching" (=scan) than the "counting" too. I have drawn the graph in Libre Office and exported to svg.

Content:

1. Scan: Search for any frequent number, e.g. "5". On the red lines are further "5" forbidden. In the upper right block the only free position for the "5" is the green place.

2. Count: For the blue field check all numbers between 1 and 9 in line and column (blue marked). The only free number is "5" for this field.

Dieses Mustersudoku is eine Abwandlung von "Cross-hatching.svg". Diese Modifikation illustriert zwei Lösungsmethoden, nicht nur das "Sichten" (=scan) (wie in "Cross-hatching.svg"), sondern auch das "Durchzählen". Ich habe diese Grafik eigenhändig in Libre Office gezeichnet und dann nach svg exportiert.

Inhaltserklärung:

1. Sichten: Nimm eine häufige Ziffer, z.B. "5". Auf den roten Linien (Zeilen und Spalte) sind weitere "5" verboten. Im oberen rechten Block ist die einzige freie Position für eine "5" das grün markierte Feld übrig und somit die Lösung.

2. Durchzählen von Kandidaten: Für das blau markierte Feld in der Mitte scheiden alle bereits vorgegebenen Ziffern (1 bis 4 und 6 bis9) in der Zeile und Spalte aus (blau eingerahmt). Die einzige verbliebene Ziffer ist die "5". Sie ist für das blaue Feld die Lösung.
