Frequently Asked Questions

What is a nonogram?

A nonogram is a logic puzzle. Each row and column has a list of numbers; each number is a run of consecutive filled cells, in order. Runs in the same line are separated by at least one empty cell. Solve every row and column and a pixel picture appears.

How do I play?

Tap a cell to paint it with the current tool. Switch tools at the bottom: Paint fills, Mark places an X on cells you believe are empty, Erase clears a cell.

What is the daily puzzle?

One puzzle per day per difficulty, the same for every player worldwide. It is generated locally from the date — no internet is needed.

What does the streak count?

It counts consecutive days on which you solved at least one daily puzzle. Missing a day resets the streak to zero.

What happens when I make a mistake?

Painting a cell that should be empty counts as one mistake. There is no fail state — you can keep solving — but your share card will show the mistake count.

Are mistakes shown immediately?

No. The grid does not reveal which cell was wrong; you have to use the row and column clues to figure it out. This preserves the logic puzzle.

Why are some puzzles harder than others?

Difficulty (Easy, Medium, Hard) changes the grid size and how densely cells are filled. Easy is 5×5 with denser fills; Medium and Hard are 10×10.

Where is my progress stored?

On your device only. Uninstalling the app removes it. There is no cloud sync and no account.

I think today's puzzle has more than one solution.

Procedurally generated nonograms can occasionally accept more than one valid pixel pattern. Any pattern that satisfies every row and column clue is accepted as a correct solve.

I found a bug. How do I report it?
