4. Step 4: Row 6 - the clue 7 fills the whole line. (7 filled)

Tips for 7x7 grids

On a 7x7 grid, start with every row and column whose clues cover more than half its length. The overlap fixes the middle cells, and each filled cell gives you a head start in the crossing line.

Where players go wrong on Level 20

• The longest line is Row 5 with the clue 7, and it is a full line: its blocks and gaps add up to the whole length, so fill it first and let it anchor the lines that cross it.
• Row 2 has the fewest filled cells (3). Cross out its empty cells early; they keep the columns honest.
• The last line the logic finishes is Row 7. If you are stuck there, every other line is already done, so recount its clue 3.
