Russian box is a very classic games, is also bringing the game safe, swept the world, Jingjiubucui, is to learn object-oriented programming thinking of the ideal example. Now the object-oriented computer programming language a lot, can be programmed to achieve. The graduation project presentations by DELPHI language to design a "Tetris" game the process, the entire game system is a module embedded in a small applications, through the modules to make calls, game design process involved in the framework of the game, the game interface The preparation, start menu the realization of the definition of variables, the algorithm designed to achieve; has also drawn the game box, rotation and in the course of the game box does not flicker, no scope, automatic sinks, fixed graphics, eliminating the achievement of full line And so on.
