題目要求：
制作一個數獨游戲。數據游戲拼圖由一個3*3的九宮格組成，每個格式又分成一個小九宮格，共九九八十一個小格子。游戲規則：游戲開始前會有一些格式了寫好了1-9的數，在剩下的格式里填寫1-9的數，直到把所有格式填滿，要求任何一行或一列或者任一個小九宮中沒有相同的數字。拼圖示例如下：

任務要求：
（1） 可以根據在九宮格中初始給出的數字個數設定游戲難度，如初始給出30個數設定為難、35個數設定為中等難度、40個數設定為容易。
（2） 對于初始給出的數據要能驗證題目的合法性（即驗證給出數據本身是否符合游戲規則，行、列及小九宮中不能出現重復數字1-9），對玩游戲中填入的數字在提交后要能驗證其正確性（任何一行或一列或者任一個小九宮中沒有相同的數字）。
（3） 程序能保存玩家的信息、游戲記錄以及成績（最高分），并能夠在游戲結束時查看玩家排名。

工作流程如下：

該數獨游戲需要連接數據庫，登錄用戶和保存數據記錄，連接數據庫創建表等暫不作顯示。主要數獨游戲部分（除去登錄頁面，注冊頁面，查看排名頁面不做顯示）分為Main（生成數獨，將生成100個數獨保存在文件中，也可以不保存，每次生成數獨都為一次新的數獨不做記錄，效率較差）和Play（數獨顯示頁面，同時包括填寫數獨和判斷數獨是否正確）兩類。

最后生成數獨頁面的效果如下：
