The lesson in words
From the overlap, the second column now has its top square filled (highlighted). Its clue is 2 1 2.
A filled square touching the edge must be the start of the first run. Here that run is 2 long, so it covers the top two squares, and the square after it must be empty.
Finish the run.
Try it: Tap the square that completes the second columnâs first run.
A run of 2 is now finished, so the next square must stay empty. On the real board youâd cross it out.
Try it: Tap the square that must be empty.
Edges start runs, and crosses mark whatâs empty. Work rows, then columns, then rows again, and the picture appears.
Questions
What does the edge method tell you about the third column?
Same as before: the first run is 2 long and starts at the edge. Every square you fill in a column is new information for its row, and the other way round.
