### 5/5 — 还不错

*2026-08-28*

还不错

### 5/5 — 有望成为ios最好的一款数独游戏

*2026-06-09*

1、使用感受：我下载过80%以上的数独app，做的都不完美。这个app的制作人在B站上有讲解视频，更新视频，我去留过言，后来留言内容被实现，app真的有更新。从最开始到今天，越做越好，就感受和系统的设置而言，目前绝对算得上第一梯队。我现在只保留了我认为最好的两个数独app，一个是这个，因为这个的整体使用感受好。另外一个是难度很高的数独，常常一道题，各种技巧，各种思考，一道题深陷其中1小时以上。

2、数独理解：数独的世界，等级森严。做到最后，难度达到最高阶段时，让人上瘾的是解题时我们自己的状态，我们被数独吸引，进入“心流”状态，而app在这个过程里不是冰冷的，它是有温度的，它也是会表达的，它告诉我们：世界太吵，来这，躲进数字里。时间失去形状，只剩下全神贯注的呼吸，和逻辑破局时清脆的回响。在确定与排除之间，重建内心的秩序感。

只有深深热爱过，你才会理解——极致的专注，就是最深的治愈。所以，从来不是我们在玩“app”，是那一刻“app”赋予了我们所有爱好者——自由！

### 5/5 — 无广告

*2026-05-27*

强烈推荐，无广告，非常好玩

### 5/5 — 互联网精神开放共享

*2026-05-27*

制作者是真玩游戏的，知道痛点在哪。

### 5/5 — 棒极了

*2026-05-06*

完美的软件，以前用全民数独，后来老是闪退，一直没找到合适的，好久没玩了，现在好了

### 5/5 — 宝藏软件

*2026-01-19*

宝藏软件

### 5/5 — 我不知这款数独如何让人开心？

*2026-01-05*

我自定义两道题，只能自己手工解，我开心不起来。

**Developer response:** 感谢你的反馈。
用户需要什么功能，我就加什么功能。
下个版本增加 [自定义数独+自动解题]功能，敬请期待！
