🖼 A hidden picture is waiting inside the grid. Use the numbers above each column and beside each row to work out which squares to fill in — the answer key sits at the bottom, fold it backward along the dotted line before you start.
A logic-grid picture puzzle (also called picross or griddlers). Use the number clues to fill in the correct squares and reveal the hidden image.
Each number tells you how many squares in a row to fill in that line, in order. A clue of 2 2 means: fill 2 squares, leave at least one blank, then fill 2 more.

How to Solve This Nonogram
Nonograms (also called picross, griddlers, or hanjie) are logic puzzles that hide a picture inside a grid of numbers:
Start with the biggest clues. A row or column clue close to the full width tells you the whole line is nearly filled — mark those first.
Watch for lone single clues. A clue of just 1 sitting between two solved lines can often be pinned down early using the cells already fixed above and below it.
Work the overlap. When a clue number is more than half the line's length, the middle cells must always be filled no matter how the run shifts — mark those immediately.
Not sure where to begin? Here's exactly how Mr. Puzzle opens this grid. Rows are numbered top to bottom and columns left to right.
Four full columns, one empty one. Columns 2, 3, 4 and 5 all have a clue of 15, which is the entire column. Fill all four top to bottom. Column 15 has a clue of 0, so mark every square in it with an ✕. That's a quarter of the grid done before you've really started.
The bottom two rows. Row 14 has a clue of 14, and column 15 is empty, so the run has to fill columns 1 through 14 exactly. Row 15 (13) has one square of wiggle room in that same space, so columns 2 through 13 are certain.
The long rows up top and in the middle. Rows 1–4 and 8–10 each have one long run, and that run has to include the squares you filled in columns 2–5. That means it can only start in column 1 or column 2. Row 1 (10) is therefore filled through column 10, row 2 (11) through column 11, and rows 3, 4, 8 and 10 (12) through column 12.
Rows with two runs. Rows 5, 6, 7, 11 and 12 all start with a 4. You already have four filled squares in columns 2–5, so that's the whole first run. Column 1 and column 6 must be blank in those rows. Mark them, and the two empty pockets in the picture start to show.
Stuck? Click for a nudge
Look at column 14 (3 4) and column 13 (5 6). The rows that only reach column 12 can't touch them, so those clues only fit in the rows whose second run stretches out to the right edge.
Why It's Rated Easy
Four complete columns and one empty column give away 60 filled squares and 15 blanks in the first minute. After that, every row's first run is locked against that solid left side, so the right-hand curves fall into place one line at a time. You never have to guess.
Spoiler: what does this puzzle hide?
Bravo if You Can Solve This One hides a bold capital letter B — a straight spine down the left with two stacked bumps bowing out to the right. It's part of a growing series of block-letter nonograms on The Puzzle Solver.
