怎么玩扫雷？
扫雷是史上最经典的逻辑推理小游戏之一。雷区由许多方块组成，其中随机埋着若干颗地雷。你的目标只有一个——翻开所有不是雷的方块，同时一颗雷也别踩到。
翻开一个安全方块后，上面会出现一个数字（1–8），它表示与这个格子相邻的 8 格里一共埋了几颗雷；如果方块是空白的，说明周围一颗雷都没有，系统会自动帮你连开一大片。整局游戏，就是靠这些数字一步步把雷的位置推理出来。
操作方式
- 翻开方块：直接点击（手机上轻点）。
- 插旗标雷：电脑上右键点击；手机上长按方块；或先打开上方的「插旗模式」，之后每次点击都是插旗。
- 快速连开（和弦）：当一个数字周围已插好对应数量的旗后，再点一下这个数字，就会一次性翻开剩下的相邻方块——高手提速的关键。
- 用「简单 / 困难」切换雷区大小；首次点击永远安全，绝不会一上来就踩雷。
从新手到高手的策略
- 从数字「1」入手。一个 1 的旁边如果只剩一个未知格，那个格一定是雷——先把它标上。
- 善用「满足」的数字。当某个数字周围的雷已全部标出，它周围其余的格子一定安全，可以放心连开。
- 记住经典花样。边线上的「1-2-1」与「1-2-2-1」有固定解法：1-2-1 中两个 1 的外侧是雷、2 的下方安全。认出花样，就不必每次重新推理。
- 实在无解就算概率。当逻辑走到死路，比较各处「这一格是雷」的概率，挑最小的赌——并优先翻能带出更多信息的角落与边缘。
扫雷的魅力正在于：它表面靠运气，实际上绝大多数步骤都能被严格推理出来。运气只在残局的极少数关口才真正登场。想深入了解背后的概率与计算复杂度，读读这篇 《扫雷的逻辑与概率：高手靠的不是运气》。
关于这款游戏
这是昼夜工坊原创的 扫雷网页版：首次点击安全、自动连开空白区、支持插旗 / 长按 / 和弦快开，并会把你每个难度的最佳用时保存在本机。免费、无需下载、手机电脑通用，随时来清一片雷区。
常见问题
第一下会不会就踩到雷？
不会。我们保证你的第一次点击及其周围一圈都没有雷，所以开局总能安全展开一片区域。
手机上怎么插旗？
长按方块即可插旗 / 取消；或打开「插旗模式」，之后每次轻点都是插旗。
「和弦」连开是什么？
当一个数字旁边已插好等量的旗，再点这个数字一下，就会一次翻开周围其余方块——前提是旗插对了，插错会踩雷。
成绩会保存吗？
会，你每个难度的最佳通关用时都保存在本机浏览器中。
How to play Minesweeper
Minesweeper is one of the most classic logic-deduction games ever made. The field is a grid of tiles, with a number of mines hidden at random. Your single goal: reveal every tile that isn't a mine — without ever clicking one.
When you reveal a safe tile, a number (1–8) appears showing how many mines sit in the 8 tiles around it. If a tile is blank, none of its neighbours are mines, so the game opens up the whole connected area for you. The entire game is about deducing where the mines are from those numbers.
Controls
- Reveal a tile: click it (tap on mobile).
- Flag a mine: right-click on desktop; long-press on mobile; or turn on Flag mode above and every tap places a flag.
- Chord (fast open): once a number has the right count of flags around it, click that number again to open all the remaining neighbours at once — the key trick for speed.
- Switch field size with Easy / Hard. Your first click is always safe — you can never lose on move one.
From beginner to expert
- Start from the 1s. If a "1" has just one unknown neighbour left, that tile must be the mine — flag it.
- Use "satisfied" numbers. When a number already has all its mines flagged, every other neighbour is safe to open.
- Learn the patterns. The edge "1-2-1" and "1-2-2-1" have fixed solutions: in 1-2-1 the tiles outside the two 1s are mines and the tile below the 2 is safe. Recognise the shape and you skip the reasoning.
- When stuck, play the odds. At a dead end, compare the probability of "mine here" across spots and take the lowest — preferring corners and edges that reveal the most new information.
That is the charm of Minesweeper: it looks like luck, but the vast majority of moves can be proven by pure logic. Luck only truly enters at a few rare endgame forks. For the probability and computational complexity behind it, read "The Logic and Probability of Minesweeper".
About this game
This is an original Minesweeper by Day & Night Studio: safe first click, auto-flood of blank areas, flagging via right-click / long-press / chording, and your best time saved per difficulty. It's free, no download, phone and desktop. Clear a field whenever you like.
FAQ
Can I lose on the very first click?
No. We guarantee your first click and the ring around it are mine-free, so the game always opens a safe area to start.
How do I flag on mobile?
Long-press a tile to flag / unflag, or turn on Flag mode so every tap places a flag.
What is "chording"?
When a number has the matching number of flags beside it, click that number again to open all remaining neighbours at once — if your flags are right. Wrong flags will blow up.
