服务条款 · Terms of Service
使用挖冷门（https://play.walengmen.com/walengmen/）即表示你同意以下条款。中文为主要文本，英文供参考。
By using Rare Dig (https://play.walengmen.com/walengmen/) you agree to these terms. The Mandarin text comes first; the English is provided for reference.
1. 运营者 / Who runs it
挖冷门是一款原创中文网页问答游戏，由美国的个人开发者 Jeffery Liu 运营，不属于任何公司。本网站不声称拥有任何政府许可、备案或平台认证。联系邮箱：[email protected]。
Rare Dig is an original Mandarin web trivia game run by Jeffery Liu, an individual developer in the United States, not by a company. The site does not claim any government licence, filing or platform certification. Contact: [email protected].
2. 免费游戏 / A free game
网站完全免费：不需要账号，不收取任何费用，不出售任何内容，也不展示广告。每天北京时间 0 点开放新的一轮（七道题），当天这一轮、结果页和分享都免费。每台设备对每一轮的首次提交计入统计。
The website is free: no account, no charges, nothing for sale and no ads. A new seven-question round opens every day at 00:00 Beijing time, and that day’s round, its results and sharing are free. Each device’s first attempt at a round is the one that counts in the statistics.
3. 金币和往期题组 / Coins and past rounds
金币只能通过玩游戏获得，例如完成每日一轮和达成成就。金币不出售，不能充值、提现、转让或兑换现金或任何实物，没有现金价值。金币只能在游戏内使用：结果页的“继续挖”可以用 20 金币打开一轮已发布的往期题组。
Coins are only earned by playing, for example by finishing the daily round and reaching achievements. Coins are never sold and cannot be topped up, cashed out, transferred or exchanged for money or goods; they have no cash value. Coins are only used inside the game: “Keep digging” on the results screen opens one released past round for 20 coins.
金币和用金币打开的内容只保存在当前浏览器，清除本站数据或更换设备后无法恢复。金币和外观不影响分数。我们可以调整金币的获得方式和用途，但不会因此收费。
Coins and what you open with them live only in this browser and cannot be recovered after you clear this site’s data or switch devices. Coins and cosmetics never change scores. We may change how coins are earned or used, but such a change never introduces a charge.
4. 公平使用 / Fair play
请不要用脚本、爬虫或自动化手段批量请求题目、伪造提交或干扰服务，也不要在漏答反馈中填写个人信息。对异常或伪造的提交，我们可以不计入统计。
Do not use scripts, scrapers or other automation to pull rounds in bulk, forge submissions or disrupt the service, and do not put personal information in missing-answer reports. We may leave abnormal or forged submissions out of the statistics.
5. 题目、评分和数据 / Questions, scoring and data
题目与答案表依据结果页列出的来源整理，开放类别可能漏收正确答案。已发布题组的答案和分数固定不变；反馈只用于以后的题组。百分位来自真实提交；起步阶段的估计会单独标注为估计。英文界面是同一中文题库的只读翻译。我们如何处理游玩数据，见数据说明。
Questions and answer lists are built from the sources shown on each results page, and open categories can miss valid answers. Released answers and points stay fixed; feedback only shapes future rounds. Percentiles come from real submissions; early starter estimates are labelled as estimates. The English interface is a display-only translation of the same Mandarin bank. How we handle play data is described on the privacy page.
6. 权利 / Ownership
游戏的文字、题目编排、画面和代码归运营者所有。第三方来源数据按各自许可使用，许可和下载链接列在结果页及数据说明中。你可以自由分享自己的成绩。
The game’s text, question design, visuals and code belong to the operator. Third-party source data is used under its own licences, which are listed with download links on the results pages and the privacy page. You are free to share your own results.
7. 服务变化和责任 / Changes and liability
这是一款试运营中的免费游戏，可能出现中断、延迟或错误。我们可以修改、暂停或停止部分或全部服务。在法律允许的范围内，本服务按现状提供，我们不对因使用本服务产生的间接损失负责。本条款不限制你依照所在地法律享有的、不可放弃的权利。
Rare Dig is a free game in an early release and can be interrupted, delayed or wrong. We may change, pause or end any part of the service. To the extent the law allows, the service is provided as is, and we are not liable for indirect losses from using it. Nothing here limits rights that your local law gives you and that cannot be waived.
8. 条款更新 / Updates
条款更新时会修改本页日期。如果网站今后加入任何付费内容或广告，会先更新本页和数据说明。
When these terms change, the date below changes too. If the website ever adds anything paid or any ads, this page and the privacy page will be updated first.
Updated / 更新: 2026-11-12.
