俄罗斯方块程序 ：

1、功能完整，直接使用 2、模块独立性强，移植方便，外部仅init和move函数，修改显示和输入即可

3、对减少内存占用、尽量减少屏幕操作进行适当优化 4、新方块生成高度随机，绝对无规律-Tetris procedure: 1, full-featured, direct uses 2 modules more independent, transplant easily, external only init and move functions, modify the display and input can be 3 to reduce memory footprint, the appropriate action to minimize the optimization of the screen 4 The new box generates a high degree of random, absolutely irregular
