玩法说明与常见问题How to play & FAQ
「扫雷」怎么玩？How do I play Minesweeper?
翻开所有不是地雷的格子就赢了。翻开的数字表示周围 8 格里有几颗雷，据此推断哪里有雷并插上旗子。点笑脸可以重新开始。Reveal every square that is not a mine to win. A number tells you how many of the eight neighbouring squares hold mines — use it to work out where they are and flag them. Click the face to restart.
第一下会踩到雷吗？Can the first click hit a mine?
不会。地雷在你第一次点击之后才布置，并且会避开你点的格子和它周围的 8 格，所以第一下总会翻开一片区域。No. Mines are placed after your first click and avoid that square and its eight neighbours, so the first click always opens an area.
手机上怎么插旗？How do I flag on a phone?
长按格子约半秒即可插旗或取消；也可以打开「🚩 插旗模式」，之后每次点按都是插旗，再点一次按钮切回翻开。Long-press a square for about half a second to place or remove a flag, or switch on 🚩 Flag mode so every tap flags; tap the button again to go back to revealing.
什么是「双击翻开」（Chording）？What is chording?
在已经翻开的数字上点击（或鼠标中键），如果它周围插的旗数正好等于这个数字，其余未插旗的相邻格会一次全部翻开。旗子插错的话会踩雷，请小心。Click (or middle-click) an opened number: if the flags around it equal the number, all its other neighbours are revealed at once. If a flag is wrong you will hit a mine, so be careful.
三种难度和自定义的规格是什么？What are the board sizes?
初级 9×9、10 颗雷；中级 16×16、40 颗雷；高级 16×30、99 颗雷；自定义最多 30 行 × 50 列。各难度的最佳用时会保存在你的浏览器里。Beginner 9×9 with 10 mines, intermediate 16×16 with 40, expert 16×30 with 99, and custom boards up to 30 × 50. Best times per level are saved in your browser.
