Today's Nonogram tips
- This 15×15 Nonogram’s final picture uses about 42% of the cells.
- On average, rows have 3.8 hint groups and columns 3.7 — use that to judge how busy a line is.
- Alternate between rows and columns — every confirmed block can unlock multiple other lines.
- Mark blanks with X’s early. A clean view of what must stay empty makes harder lines much easier.
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.
