One person reads every message, so please say which app you are writing about. Your iPhone model and iOS version usually save a round trip.
Place one O in every row, every column and every colour region, and mark the rest with X. Two O’s can never touch, not even at a corner. Double-tap a square to place an O. Every level can be solved by reasoning alone; you will never need to guess.
Ads need a working internet connection, and in some regions the ad network cannot be reached at all. The game is built so this never blocks you: if an ad cannot be shown, you keep playing anyway.
Progress is kept on the device only, so deleting the app clears it. There is no account and nothing is uploaded. Updating the app through the App Store is safe — that keeps everything.
The daily challenge and the daily check-in both open at level 20.
Yes. There is nothing to buy, and no account to create. Watching an ad for an undo or a hint is always your choice.
On the computer, open deskdrop.me in any browser. A code appears. In Deskdrop, tap Scan and point the camera at that code. Photograph your pages, tap Send, and the PDF arrives in the browser.
A code from the web page is good for one transfer and expires after 15 minutes. Reload the page for a fresh code and scan it again. If you want a computer that stays paired, install the desktop receiver below.
No. The web page is enough, which is why it works on a machine you do not own. On your own computer, the free receiver for Windows or macOS drops scans into a folder silently, with no page to open. Get it at deskdrop.me/download.
Uploads resume where they stopped, so wait rather than starting over. If the phone and the computer are on the same Wi-Fi, allow the local network prompt: the file then goes straight across instead of through our server, which is much faster.
Thirty or more is fine. They arrive as one PDF, not as separate files. The cleanup pass keeps the file small enough to email.
No, and that is deliberate. Pages are encrypted on your phone, so we never hold the key, and the encrypted pieces are deleted as soon as your computer confirms it has them. Send it again from the phone.
每一封都是同一个人在看，所以请说明你写的是哪一款应用。 附上 iPhone 型号和系统版本，通常能少来回一趟。
每一行、每一列、每一个色区，各放一个 O，其余格子用 X 排除。两个 O 不能挨着， 斜着碰角也不行。双击格子就能落子。每一关都能靠推理解出来，不需要靠猜。
广告需要能正常联网，而且在部分地区广告服务本身就访问不到。 游戏在设计上不会因此卡住你：广告出不来，照样能继续玩。
进度只存在你的手机上，删除 App 就会一并清除。游戏没有账号，也不会上传任何东西。 通过 App Store 更新版本是安全的，进度都在。
每日挑战和每日签到都在第 20 关之后开放。
是。没有任何内购，也不用注册。为了撤销或提示去看广告，永远是你自己决定。
在电脑上用任意浏览器打开 deskdrop.me， 页面会显示一个二维码。在 Deskdrop 里点 Scan 对准它，拍好页面后点发送， PDF 就出现在电脑的浏览器里。
网页上的码只能用一次，15 分钟后失效。刷新页面拿一个新码重扫即可。 如果希望电脑长期保持配对，装下面的桌面接收端。
不需要，网页就够了，所以在不属于你的电脑上也能用。 如果是自己的电脑，Windows 和 macOS 的接收端是免费的， 扫描件会静默落到指定文件夹，连网页都不用开。 下载地址 deskdrop.me/download。
上传会从断点续传，等一下就好，不必重来。 如果手机和电脑在同一个 Wi-Fi 下，请允许本地网络权限， 文件会直接在两者之间走，不经过我们的服务器，快很多。
三十张以上没问题，并且合成一个 PDF，而不是一堆散文件。 增强处理会把体积压下来，方便直接发邮件。
不能，这是刻意的设计。页面在手机上就已加密，我们从不持有密钥， 电脑确认收到后密文立即删除。请在手机上重新发送一次。
