Nonocross Puzzle 55 Answer — Hedgehog
Nonocross Puzzle 55, Hedgehog, is a 10×10 grid with 55 filled cells and 45 empty cells in the stored game board. The completed board is shown below with its row and column clues. These clues allow 2 valid grids, so the displayed board is a verified solution but not the only arrangement that satisfies every clue.
Use the clue tables and forced-cell information to compare your progress. A board can differ from the stored picture in the uncertain cells and still be correct if every row and column clue is satisfied.

Does Nonocross Puzzle 55 Have More Than One Solution?
Yes. A solver found 2 different grids that satisfy every row and column clue.
Of the 100 cells, 96 are identical in every valid grid and 4 can change between valid solutions. The displayed board is the grid stored with the puzzle, but another arrangement can also be correct if it satisfies every clue.
How to solve it
How to Solve Nonocross Puzzle 55
Start with the lines that need no thinking: Row 6 (1 4 1 1 on 10 cells), Column 4 (7 2 on 10 cells). A clue that adds up to the full length of its line, counting one gap between groups, can be filled straight away.
The strongest overlap is Row 9: its clue 8 needs 8 of the 10 cells, leaving 2 spare. The block of 8 can slide by at most 2, so cells 3–8 are filled in every placement.
Single-line deductions fix 41 of the 100 cells in the first pass and 96 after 5 passes, then stall. The remaining 4 cells are not forced by line logic alone.
Deductions
Step-by-Step Deductions for Puzzle 55
These deductions come from the actual clues of puzzle 55, applied one line at a time and repeated until nothing new follows.
Pass 1 · Row 6
(clue 1 4 1 1 on 10 cells): cells 1, 3–6, 8, 10 must be filled and cells 2, 7, 9 must be empty, whatever the rest of the grid holds.
Pass 1 · Column 4
(clue 7 2 on 10 cells): cells 1–7, 9–10 must be filled and cell 8 must be empty, whatever the rest of the grid holds.
Pass 1 · Row 9
(clue 8 on 10 cells): cells 3–8 must be filled, whatever the rest of the grid holds.
Pass 2 · Row 7
(clue 3 1 1 1): using the cells already fixed by crossing lines settles 5 more cells.
Pass 3 · Row 3
(clue 6 1): using the cells already fixed by crossing lines settles 5 more cells.
Watch out
Common Mistakes in Nonocross Puzzle 55
Joining two groups
Row 1 reads 1 1 1 1. In the finished board the groups of 1 and 1 are separated by a single empty cell (cell 5). Filling it would merge them into one block of 3 and break the clue.
Treating a different valid grid as an error
4 cells of this puzzle can legitimately differ between valid grids. If your board satisfies every row and column clue it is a valid solution, even if it does not match the stored picture.
Overthinking a full line
Row 6 (clue 1 4 1 1 on 10 cells) has no spare cell, so every position in it is decided by the clue; there is nothing to test.
Using the answer
How to Check Your Nonocross Puzzle 55 Answer
Read the filled-cell groups in every row and column of your grid and compare them with the clue lists above. In this puzzle row 1 must read 1 1 1 1 and column 1 must read 1 2; the last row must read 1 1 and the last column 1 3.
The line with the most groups is Row 7, which must read 3 1 1 1; it is the quickest place to spot a merged or split group.
