Frequently Asked Questions
Can I play offline?
Yes. The complete game works offline. Game Center scores and achievements are submitted when the service becomes available.
Is Game Center required?
No. You can decline Game Center authentication and continue playing normally.
How are pieces generated?
Each new set is checked against the current board. The game avoids a set that would end the run immediately while preserving meaningful difficulty.
Can deleted local records be restored?
Local records are stored on the device and are removed when the app is deleted. Submitted Game Center scores and achievements remain subject to your Apple Game Center account.
What is Crystal Edition?
Crystal Edition is a one-time In-App Purchase that removes interstitial ads and unlocks additional visual palettes and sound profiles. It never changes scoring, piece generation, or leaderboard eligibility.
How do I restore Crystal Edition?
Open Settings and choose Restore Purchases while signed in to the Apple Account used for the original purchase. The App Store handles the purchase; never send us payment-card details or your Apple Account password.
When can an advertisement appear?
The free version may show a low-frequency interstitial only after a completed run when you choose Play Again or Home. There are no banner ads and no ads during a run.
How do I change privacy choices or report an ad?
When required in your region, Settings shows Privacy Choices. To report an advertisement, include the approximate time, your country or region, and a screenshot when available.

可以离线游玩吗？
可以。完整游戏支持离线游玩；Game Center 恢复可用后会继续提交待同步的成绩和成就。
必须登录 Game Center 吗？
不需要。取消 Game Center 登录不会影响本地游戏。
候选方块是怎样生成的？
每组候选都会结合当前棋盘进行检查，避免刷新后立即结束，同时保留足够的规划难度。
删除游戏后能恢复本地纪录吗？
本地纪录保存在当前设备，删除应用后会一并移除。已经提交的排行榜成绩和成就由 Apple Game Center 账户管理。
Crystal Edition 是什么？
Crystal Edition 是一次性内购，可永久移除插屏广告并解锁更多视觉主题和音效方案。它不会改变分数、候选生成或排行榜资格。
如何恢复 Crystal Edition？
使用原购买所用的 Apple 账户登录，在设置中点击 Restore Purchases。请勿向我们发送银行卡信息或 Apple 账户密码。
广告会在什么时候出现？
免费版只可能在一局结束、选择再次游玩或返回首页后低频展示插屏。游戏进行中没有广告，也没有横幅广告。
怎样修改广告隐私选择或举报广告？
在适用地区，设置页会显示 Privacy Choices。如需举报广告，请提供大致时间、国家或地区，并在方便时附上截图。
