🍄 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 column clue of 2 then 5 (stacked) means: fill 2, leave at least one blank, then fill 5 more, top to bottom.

Nonograms (also called picross, griddlers, or hanjie) are logic puzzles that hide a picture inside a grid of numbers:
This puzzle steps up to a 10×8 grid with a few split runs, so it's a good second nonogram once you've solved an easy one. For the full method, edge logic, and tougher techniques, read our complete guide to nonograms and advanced nonogram techniques.
Lucky Mushroom is our second printable nonogram — a step up from Hidden Heart with a couple of split runs to test the overlap technique. It prints on one page with the fold-over answer key so you can check yourself honestly.
