Hard

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. Long row clues like the 23 in this puzzle nearly span the full 25-wide grid — almost the whole line is filled, so mark those cells first and let them anchor everything else.
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.

This puzzle is a 25×25 grid. For the full method, edge logic, and tougher techniques once you're ready to level up, read our complete guide to nonograms and advanced nonogram techniques.

Walkthrough: Your First Four Moves

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.

Clear the edges. Rows 24 and 25 have no clue, and neither do columns 1 and 25. The working width is columns 2 to 24 (23 squares).
Rows 15 and 16 (23). Exactly the working width, so fill columns 2 through 24 in both.
Rows 14 and 17. Row 14 (4 18) adds up to 4 + 18 + one gap, exactly 23. It fits only one way: columns 2–5, a blank at column 6, then columns 7–24. Row 17 (21) has 2 squares of wiggle room, so columns 4 through 22.
Column 13 (22). In 23 rows, there's 1 square of wiggle room, so rows 2 through 22 are filled. That long line runs right through the middle of the picture.

Stuck? Click for a nudge

At the top, column 13's long run already reaches row 2. Rows 1 to 5 (3, 6, 7, 1 6, 1 6) build out to the right from it.

Why It's Rated Hard

A big, mostly solid 25×25 with a narrow gap running down the left side (rows 11 to 14). Plenty of free squares to start, then patient work on the edges. No guessing.

Spoiler: what does this puzzle hide?

One a Day Keeps the Doctor Away hides a round orchard fruit, dimpled at the top where a short stem and a single leaf sprout — the crisp lunchbox classic from the old proverb. Build the wide filled rows through the belly of the grid first, where most lines run nearly the full width, then use the narrow clues up top to place the stem and leaf and finish the fine detail.
