Is Nonocross Puzzle 57 Unique?
Yes. A solver enumerated every grid that satisfies all 10 row clues and 10 column clues and found exactly one. The displayed board is therefore forced by the clue set.
How to solve it
How to Solve Nonocross Puzzle 57
Start with the lines that need no thinking: Column 3 (1 1 6 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 5: its clue 5 1 1 needs 9 of the 10 cells, leaving 1 spare. The block of 5 can slide by at most 1, so cells 2–5 are filled in every placement.
Applying these single-line deductions to every row and column, then repeating with what is known, fixes 18 of the 100 cells in the first pass and completes the grid in 10 passes. No guessing is needed.
Deductions
Step-by-Step Deductions for Puzzle 57
These deductions come from the actual clues of puzzle 57, applied one line at a time and repeated until nothing new follows.
Pass 1 · Column 3
(clue 1 1 6 on 10 cells): cells 1, 3, 5–10 must be filled and cells 2, 4 must be empty, whatever the rest of the grid holds.
Pass 1 · Row 5
(clue 5 1 1 on 10 cells): cells 2–5 must be filled, whatever the rest of the grid holds.
Pass 1 · Row 7
(clue 1 5 on 10 cells): cells 6–7 must be filled, whatever the rest of the grid holds.
Pass 2 · Row 1
(clue 4): using the cells already fixed by crossing lines settles 5 more cells.
Pass 3 · Column 6
(clue 3 1): using the cells already fixed by crossing lines settles 7 more cells.
Watch out
Common Mistakes in Nonocross Puzzle 57
Joining two groups
Row 4 reads 1 3 1. In the finished board the groups of 3 and 1 are separated by a single empty cell (cell 9). Filling it would merge them into one block of 5 and break the clue.
Overthinking a full line
Column 3 (clue 1 1 6 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 57 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 4 and column 1 must read 1 2; the last row must read 2 3 and the last column 2 2.
The line with the most groups is Row 6, which must read 1 1 1 1; it is the quickest place to spot a merged or split group.
