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.

About This Puzzle

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.
