About Nonogram
Classic nonograms by candlelight: 240 hand-drawn pictures in eight folios, from lanterns and ravens to dragons. One folio is drawn from our novel, The Cistern Heresy.
Every board is proven solvable by logic alone, so it has exactly one answer. No lives, no mistake limit, no countdown.
How to play
- Goal
- Fill the cells the clues describe to reveal the picture.
- How it ends
- A picture is solved when every row and column matches its clue. There is no way to lose.
- Record
- The fastest first solve of each picture, with its holder's name.
- The numbers give the runs of filled cells in each row and column, in order.
- Fill the cells they describe to reveal the picture. Cross cells you know are empty.

Tips
- Start with the big numbers. A run longer than half the line always covers its middle cells.
- Cross what cannot be filled. Crosses make the next deduction visible.
- Use Zoom on a phone. The clue numbers stay pinned while you move around a large board.

Questions
Can a board need guessing?
No. Every board was solved row by row and column by column with logic alone before it was added, which also proves it has only one answer.
What is the Cistern Heresy folio?
Thirty pictures of things from our novel of that name; each finished picture shows the line of the book it comes from.
What does Check do?
It marks wrong cells. A board finished after Check does not count for the best time.
Is my progress saved?
Yes, in this browser. Nothing is sent anywhere except an unaided best time.
