玩法说明与常见问题How to play & FAQ
「数织」怎么玩？How do I play Nonogram (Picross)?
每行左边和每列上方的数字表示这一行/列里连续涂黑格子的段长，按顺序排列，段与段之间至少隔一个空格。例如「3 1」表示先有连续 3 格，再隔至少一格后有 1 格。根据这些线索推理出所有该涂黑的格子。The numbers beside each row and above each column give the lengths of the filled runs in that line, in order, with at least one empty square between runs. “3 1” means a run of three, a gap, then a single square. Use the clues to deduce every filled square.
题目一定有唯一解吗？Does every puzzle have a unique solution?
是的。每道题生成后都会用逐行逐列的逻辑求解器验证，能够不猜测地完全解开才会出题，所以答案唯一。Yes. Each generated puzzle is checked with a line-by-line logic solver and only kept if it can be solved completely without guessing, so the answer is unique.
「打叉」有什么用？What are crosses for?
叉只是你自己的标记，表示“确定是空格”，方便推理；它不影响判定，完成时会自动清掉。Crosses are just your notes for squares you know are empty; they don’t affect checking and are cleared when you finish.
线索变灰是什么意思？Why do clues turn grey?
当某一行或某一列已经和线索完全吻合时，那一组数字会变灰，方便你专注于还没完成的行列。A clue greys out once its row or column matches exactly, so you can focus on the unfinished lines.
