ALERT!: Entering some wrong answers will end the quiz
The point of Nonogram puzzles is to fill in each cell correctly. The numbers measure how many unbroken lines of filled-in squares there are in any given row or column.
To indicate a cell is filled in, type B. To indicate a cell is not filled in, type X. "3" by itself would mean that there is a group of 3 filled squares in the row or column. "2 1" would mean there is first a group of 2 squares, and then a group of 1 square comes afterward with at least 1 empty space between the groups.
