Numbers beside a grid counting runs of filled cells.
Also known as: Picross clues, Griddler notation
A nonogram's numbers give the lengths of consecutive filled runs in each row and column, in order, with at least one gap between them. The puzzle is solvable because the clues constrain each other, not because any single clue determines its line.
Give the lengths of consecutive blocks of filled cells in a row or column, in the order they occur.
Contexts: History
Require at least one empty cell between successive blocks, which is the constraint that makes the counts unambiguous.
Contexts: History
Are solvable by intersecting the constraints of rows and columns, since a single line's clue rarely determines it alone.
Contexts: History
Rows of small numerals printed along the top and left edges of an empty square grid.
