How to play Nonogram.
Each number tells you how many black cells belong together. Use the rows and columns together to uncover the picture.
1. Read the runs
A clue of 3 means one unbroken group of three black cells. A clue of 2 1 means two black cells, at least one empty cell, then one black cell — in that order.
2. Find what must be filled
In a five-cell line, a 5 fills the entire line. A 3 has three possible positions, but all of them cover the middle cell. That middle cell must be black.
3. Use empty marks
Mark a cell with × when you know it must stay empty. Separate black groups with at least one empty cell. Empty marks help your reasoning; you do not have to mark every white cell to finish.
4. Let the clues work together
A cell belongs to both a row and a column. Filling a row gives you new information for its columns. Recheck those columns, then return to the rows.
Made for a calm solve
Choose Fill, Mark or Erase, then tap or drag. One drag stays in one row or column and is one undo. On small screens, Focus enlarges the grid; Move pans it without drawing.
Arrow keys move. Space applies your selected tool. X marks empty. Delete erases. Ctrl or Command Z undoes. Escape cancels a stroke.
