Try it: The row second from the bottom has a clue of 8. Tap all its squares.
Rules check passed. Now for the methods.
Questions
A clue says 2 4. Which comes first along the line?
Runs are always in the order the clue lists them: left to right in a row, top to bottom in a column.
Can two runs in the same line touch?
No. Otherwise they’d be one longer run.
In a line of 8, a clue of 1 4 1 needs 1 + 4 + 1 squares plus two gaps. How many ways can it fit?
1 + 4 + 1 + 2 gaps = 8, the whole line. When a clue adds up to the line’s length, there’s only one way to fill it.
