Nonogram is a picture logic puzzle on a brass plate. The numbers along the rails tell you which squares to inlay. Fill in the right ones and a hidden picture comes out of the brass.
Each row and column has a rail of numbers. They are the lengths of the runs of inlaid squares in that line, in order, with at least one blank square between runs. A 0 means the line is empty.
Use the rows and columns together to work out which squares are inlaid. A rail's numbers fade once its line matches. The plate is finished when every line matches, and the picture is named.
You can rule out squares you know are empty by marking them with a cross. Crosses are only notes, and the plate never checks them.
Every plate has exactly one answer, and you never need to guess. The clock starts at your first move.
Pausing stops the clock, and the pause menu can reset the plate. A plate you leave is kept for you to carry on. Give up ends it unsolved, with no time kept, and practice shows you the answer.
Today's plate is a 10×10 picture, the same for everyone. It changes at midnight your local time. Only your first try counts, and finishing on consecutive days builds a streak. Giving up uses that try, and playing again brings back the same plate.
The "Rule out finished lines" switch crosses off the rest of a line's squares once it matches. It is off by default, because it does some of the thinking.
