《倒水解密》是一款很不錯的手機益智類遊戲，遊戲界面如下：
規則是這樣的：
有N個容量不同的瓶子，指定「將a升水倒入容量爲b的瓶子」。遊戲要求通過裝水、倒水，達成給定的目標。
該遊戲雖然簡單，但可玩性高，也可有不同的難度變化，並且能鍛鍊玩家的心算能力。《倒水解密》不失爲一個很好的繁忙工作之餘的休閒方式。
說到這裏，大家應該能猜到我想幹什麼了。沒錯，山寨之。
下面是山寨遊戲的屏幕錄像：
雖然界面有點簡陋，但至少實現了。（屏幕錄像軟件不能錄入鼠標光標，實際上鼠標光標是動態的）。
遊戲操作方式如下：
- 在瓶子上雙擊右鍵可以把瓶子灌滿水
- 雙擊左鍵可以把瓶子裏的水倒掉
- 將一個瓶子拖動到另一個瓶子上可以把水倒過去
下面是遊戲的模型結構。
Bottle類，表示瓶子。保存了瓶子的關鍵屬性如容量、儲量，以及基本方法如倒入、倒出。該類實現了IVisible可視化接口。這個接口很簡單，只是提供了一個Draw()方法，用於重繪瓶子自身並返回圖像。使用這種方式，可以方便的修改瓶子的外觀樣式而不用修改其他部分代碼。例如可以簡單的用矩形畫瓶子，也可以像上面的手機遊戲截圖一樣用非常的漂亮的貼圖來做。

遊戲的計時、計步、界面操作等統統放在主窗體，這裏不做贅述。
簡單的實現，還有倒計時、高分榜等功能可以擴展，界面也可以做的更漂亮些，歡迎大家擴展。
