Nonograms: a practical guide with interactive examples

Summary

< Back to LAB174.com This is a nonogram It’s an image puzzle. Your goal is to reveal the hidden pixel art image. You are guided in that task by the numbers around the board. Basic moves The numbers show how many cells should be filled in a given row. For example, in a row like this you should fill four cells: Try it - tap the squares below. And in a row like this you should fill one cell: But wait: which one? We don’t know yet. This is a very important technique: only fill cells when you’re certain; no guessing. In our case, we could fill one cell in four different ways: We’d have to guess the correct one. If our guess is wrong, we’d encounter inconsistencies later on. Let’s not do that. Instead, we search for a different row where we don’t have to guess. All rules that apply to rows, apply to columns too. When there are two or more numbers, this means there will be two or more groups of filled cells. And that they will be separated by at least one empty cell. Like this: Try solving the puzzle below: We mark cells that will definitely be empty with a cross. For example, if we saw a zero, we could mark all cells as empty. Or if we saw a row where all required cells have already been filled. Then we could mark remaining cells as empty. Or if we saw a completed group - then we could put a ‘cross’ at each of its ends. That’s all of the basic techniques; you’re ready to solve a nonogram! Give it a try below if you want. Tap to fill a cell, drag to fill multiple cells, crosses will be inserted for you automatically. Let’s try one more. You can now place crosses yourself too. Use the button below to toggle between filling cells and placing crosses.
