Step-by-step hints for Level 51

Press the button to reveal one step at a time. Each step fills or crosses out cells in a single row or column, in the order a careful player would find them.

1. Step 1: Column 3 - the clues 1 1 4 plus one gap between blocks add up to 8, so the whole line is fixed. (6 filled, 2 crossed out)
2. Step 2: Column 2 - the clue 3 2 leaves only 2 free cells, so the middle of each long block must be filled. (1 filled)
3. Step 3: Column 4 - the clue 1 4 leaves only 2 free cells, so the middle of each long block must be filled. (2 filled)
4. Step 4: Row 1 - with the cells already marked, only one arrangement of 2 fits these positions. (5 crossed out)

Tips for 8x8 grids

On a 8x8 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 51

• The longest line is Row 3 with the clue 7. The overlap rule fixes 6 of its cells before anything else; players who start elsewhere miss that head start.
• Row 2 has the fewest filled cells (1). Cross out its empty cells early; they unlock 4 columns.
• The last line the logic finishes is Row 4. If you are stuck there, every other line is already done, so recount its clue 1.
