🖼 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.
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.

Nonograms (also called picross, griddlers, or hanjie) are logic puzzles that hide a picture inside a grid of numbers:
This puzzle is a 15×15 grid — 15 squares across and 15 down. 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.
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.
Look at column 6. Its 5 now has squares filled in rows 7 and 9, so row 8 must be filled too, and the whole run has to sit somewhere in rows 5–11. That settles row 8 (columns 3–6) and pushes the 4 in rows 1 and 15 over to columns 2–5. From there the two arms of the K step outward one column at a time.
Every square can be worked out from the clues alone, with no guessing at any point. Two full columns and three empty ones give you a big start, and the short rows across the middle do most of the rest. The K is also a mirror image from top to bottom — row 1 matches row 15, row 2 matches row 14 and so on — so once you’ve cracked the upper arm, the lower one goes the same way. It’s still a 15×15 grid, like the rest of the alphabet series.
One Kilo, Please is part of our Phonetic Alphabet series (based on the NATO phonetic alphabet), where every puzzle hides the letter behind its call sign — and Kilo stands for a capital K. A two-square-wide stem runs down the left side with little serif feet at the top and bottom, and two thick diagonal strokes branch out from the middle of the stem, one climbing up to the right and one dropping down to the right. It follows Wherefore Art Thou, Juliett? in the series.
Did you know? “Kilo” is also everyday shorthand for the kilogram. For 130 years the official kilogram was a single metal cylinder kept in a vault near Paris, nicknamed Le Grand K. In 2019 scientists retired it and redefined the kilogram using a constant of nature instead. Before the NATO alphabet, the American and British “Able Baker” alphabet used King for K.
