Practise: W-Wing
Start with the two marked cells that share exactly the same pair. Which other marked line forces one of that pair’s digits?
The prepared notes show two matching pairs and one strong link. Follow the link first; this removes a candidate and does not place a digit yet.
Example 1 of 4
Your turn first
Your turn first
Find the two equal pairs. Which strong-link digit has exactly two homes, and which prepared 6-notes see both pair cells?
Remember
A W-Wing uses two distant cells with the same two candidates. A separate strong link for one digit touches both cells. That forces the other digit into one pair cell, so remove it only from cells that see both.
