此俄罗斯方块游戏可以为用户提供一个可在普通个人电脑上运行的，界面美观的，易于控制的俄罗斯方块游戏。

二．系统运行环境操作系统选择Windows XP 版本，运行环境选择MyEclipse三．系统功能需求描述俄罗斯方块游戏是一款适合大众的游戏软件，它适合不同年龄的人玩。

本软件要实现的功能如下：1.游戏区：玩家可以在游戏区中堆积方块，并能够在游戏过程中随时了解得分情况。

2.游戏控制：玩家可以通过游戏控制功能来选择开始新的一局游戏，暂停或退出游戏。

3.级别设置：玩家可以根据自己的需要自行设定游戏的开始级别，级别越高，游戏速度越快，难度越大。

四．总体设计游戏中玩家可以做的操作有：1.以90度为单位旋转方每一格块。

2.以格子为单位左右移动方块，让方块加速落下。

3.方块移到区域最下方或是着地到其他方块上无法移动时，就会固定在该处，而新的随机图形会出现在区域上方开始落下。

4.当区域中某一列横向格子全部由方块填满，则该列会自动消除并成为玩家的得分。

同时删除的列数越多，得分指数上升。

5.当固定的方块堆到区域最上方，则游戏结束。
