The grid contains 25 cells in 5 rows and 5 columns. A single run of 4 in an empty line of 5 must cover the 3 central cells shared by its leftmost and rightmost positions. Fill those cells even while the endpoints remain unresolved.
Alternate between row and column clues. Size determines the number of cells, while difficulty also depends on the clue arrangement. Cross out confirmed empty cells and keep unresolved cells visibly distinct.
Mark cells you know are empty with a cross and leave unresolved cells unmarked. Progress in a row supplies information for its columns. At the end, count the actual runs in every line and compare them with all its clues.
