俄罗斯方块是我们大家喜欢玩的一个游戏，但如何编写这个游戏呢，在此小编用Visual Basic个人的设计思路来实现它，供大家参考学习。
设计思路：
我们都知道俄罗斯方块的图形很简单，翻来覆去就那几种，但这些图形如何表现出来呢，小编知道两种方法：
（1），第一种是将方块所在的框架界面看作一个二维表，在这个二维表中每一个方格有两个变量，其中一个变量记录是否有方块停留在上面，另外一个变量记录停留的方块叫什么名字；
（2），第二种是用VB较擅长的图形界面实现，贪吃蛇的主要图形有"Z字形"、"反Z字形"、"7字形"、反7字形"、"T字形"、"田字形"及"长条形"及其这些图形的旋转变换而共构成19种图案，在此，在编写的过程中为使程序简洁化，我们可以用这些图形的交替变换来模拟图形的变化，因此选择第二种方法。
下面接着要说的游戏的操作方法，也很简单，方块的下落由time控件控制右移动与旋转变化由Form的KeyDown中的"↑"、"↓"、"←"、" →"进行操作。
设计步骤：
1，建立如下图所示的窗体界面
2，根据上图，自行设置各控件属性
3，右击 "ImageList1" 控件，右键选择 "属性" 菜单选项，打开如下图所示的对话框，选择 "Images" ，再点 "InsertPicture"插入19张图形素材（素材可以联系小编索取）之后确定返回。
4，建立游戏源程序代码
（1），运行函数
1. Function Get_X_Value()
2. If GetValue(1, 2) Then 'Get X Value
