🖼 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. 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.
They Call Me Delta belongs to our NATO phonetic alphabet series, where each puzzle hides the letter behind its call sign — here, a capital D. Three solid full-height columns build the straight spine down the left, while the rounded runs on the right swing out and close the loop. At 15×15 and rated easy, it’s a satisfying five-minute solve and a good showcase for the overlap trick on those long column clues.
