Puzzle 4, “Helmet,” is a 4×4 Nonocross picture puzzle. Its completed grid has 13 filled squares and 3 empty squares. The recorded row and column clues determine one valid arrangement, shown above.
Reading the Answer
■ = filled square. · = empty square. Fill the marked squares in the game; an X, where supported, only marks a square that stays empty.
Row Clues and Answer Patterns
Read each row from left to right. The clue numbers give the lengths of consecutive filled-square groups, with at least one empty square between separate groups.
| Row | Clue | Solved pattern |
|---|---|---|
| 1 | 4 | ■■■■ |
| 2 | 4 | ■■■■ |
| 3 | 1 | ■··· |
| 4 | 4 | ■■■■ |
Column Clues and Answer Patterns
Read each column from top to bottom. The completed column must contain the same filled-square groups, in the same order, as its clue.
| Column | Clue | Solved pattern |
|---|---|---|
| 1 | 4 | ■■■■ |
| 2 | 2, 1 | ■■·■ |
| 3 | 2, 1 | ■■·■ |
| 4 | 2, 1 | ■■·■ |
Check Two Clues in This Grid
Row 3 has the clue 1. In the completed picture, that row reads ■···. Its uninterrupted groups of filled squares match the clue in the required order.
Column 2 has the clue 2, 1. Reading downward gives ■■·■. The filled-square groups match the column clue, confirming that this part of the picture is consistent.
Check Your Own Grid
Want to check the squares you filled? Mark each cell as filled or empty, then compare your completed grid with the row and column clues. This checker accepts any arrangement that satisfies the clues, even when the puzzle has more than one valid solution.
Why This Puzzle Has One Valid Grid
The recorded clues admit one completed arrangement. After every row and column is checked, there is no second grid that satisfies the same clue set. The picture shown above is therefore uniquely determined by those recorded clues.
