Today's Nonogram tips
- This 20×20 Nonogram’s final picture uses about 57% of the cells.
- On average, rows have 5.6 hint groups and columns 5.7 — use that to judge how busy a line is.
- Treat each line like a mini puzzle: sketch where each hint group could go, then eliminate impossible placements.
- Avoid guessing — if a hypothetical placement forces contradictions in other hints, discard it and try another.
Use X-marks to track definite blanks — it makes tough lines way easier.

💡 How to play: Use the numbers above and to the left of the grid to decide which cells to fill. Each number shows how many squares are filled consecutively in that row or column. Use X-mode (Ctrl + left-click or just right-click) to mark cells that must stay empty — it helps eliminate options and avoid mistakes.
