免费与内购说明

Free to Play, No Ads

当前版本完全免费，没有内购也没有广告：全部玩法、每日挑战、 数独地图与学院均为免费内容。游戏内金币只能通过游玩获得（任务、结算、宝箱、成就等）， 用于购买皮肤、复活与提示加购，不涉及任何真实货币交易。

The current version is completely free, with no in-app purchases and no ads: every mode, the Daily Challenge, the Sudoku Map, and the Academy are free content. In-game coins are earned purely by playing (missions, results, chests, achievements) and spent on themes, revives, and extra hints — no real-money transactions are involved.

游戏数据在哪、怎么清掉

Where Your Data Lives & How to Clear It

所有数据（进度、金币与皮肤、任务与成就、统计与设置）只保存在你的设备本机。 我们没有云端账号，换设备或重装后数据不会迁移。卸载 App 即彻底删除全部数据； 也可以随时在「我的 → 账号与数据 → 清除本地数据」中主动清空。详见 隐私协议。

All data (progress, coins and themes, missions and achievements, stats and settings) lives only on your device. There is no cloud account — data never migrates when you switch devices or reinstall. Uninstalling the app deletes everything permanently; you can also clear it anytime under Me → Account & Data → Clear Local Data. See the Privacy Policy for details.

常见问题

FAQ

玩到一半退出，进度会丢吗？经典模式与每日挑战有断点续玩—— 退出后再进会从断点继续（每日挑战当日有效，跨日作废换新题）。

If I quit mid-game, is my progress lost? Classic and Daily Challenge both support resume — returning to the game picks up where you left off (the Daily Challenge save is valid for that day only; after midnight a fresh puzzle starts).

金币不够复活/加购提示怎么办？完成每日任务、每日挑战、地图关卡、 成就与升级都会产出金币；皮肤与道具都不必付费。

Not enough coins to revive or buy hints? Daily missions, the Daily Challenge, map levels, achievements, and level-ups all pay out coins; themes and boosters never require real money.

提示次数用完了？每局 3 次免费，可用 80 金币加购（每局上限 2 次）。 提示文案会讲解所用技巧，配合「数独学院」课程练习更快。

Out of hints? Each game includes 3 free hints, and you can buy more for 80 coins (up to 2 extra per game). Every hint explains the technique it used — pair them with Academy lessons to improve faster.
