俄罗斯方块游戏是一款经典的益智游戏，通常使用编程语言Python来实现。下面是一个简单的俄罗斯方块游戏的示例代码：

python">import pygame
import random# 定义颜色
BLACK = (0, 0, 0)
WHITE = (255, 255, 255)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
CYAN = (0, 255, 255)
MAGENTA = (255, 0, 255)
YELLOW = (255, 255, 0)
ORANGE = (255, 165, 0)# 定义方块的形状
SHAPES = [[[1, 1, 1, 1]],[[1, 1], [1, 1]],[[1, 1, 0], [0, 1, 1]],[[0, 1, 1], [1, 1, 0]],[[1, 0, 0], [1, 1, 1]],[[0, 0, 1], [1, 1, 1]],[[1, 1, 1], [0, 1, 0]]
]# 初始化游戏
pygame.init()# 设置屏幕宽高
SCREEN_WIDTH = 800
SCREEN_HEIGHT = 600
screen = pygame.display.set_mode([SCREEN_WIDTH, SCREEN_HEIGHT])
pygame.display.set_caption("俄罗斯方块")# 定义方块的大小和间隙
block_size = 30
block_gap = 2# 初始化方块的位置
x_pos = 3
y_pos = 0# 初始化方块的形状
shape = random.choice(SHAPES)# 初始化方块的颜色
color = random.choice([RED, GREEN, BLUE, CYAN, MAGENTA, YELLOW, ORANGE])# 设置游戏时钟
clock = pygame.time.Clock()# 判断方块是否可以移动
def can_move(x_offset, y_offset):for i in range(len(shape)):for j in range(len(shape[i])):if shape[i][j]:x = x_pos + j + x_offsety = y_pos + i + y_offsetif (x < 0 or x >= SCREEN_WIDTH // (block_size + block_gap) ory >= SCREEN_HEIGHT // (block_size + block_gap) orgrid[y][x]):return Falsereturn True# 绘制方块
def draw_block(x, y, color):pygame.draw.rect(screen, color, [(block_size + block_gap) * x,(block_size + block_gap) * y,block_size,block_size])# 绘制网格
def draw_grid(grid):for i in range(len(grid)):for j in range(len(grid[i])):if grid[i][j]:draw_block(j, i, grid[i][j])# 更新网格

def clear_rows():full_rows = []for i in range(len(grid)):if all(grid[i]):full_rows.append(i)for row in full_rows:del grid[row]grid.insert(0, [BLACK] * (SCREEN_WIDTH // (block_size + block_gap)))# 初始化网格
grid = [[BLACK] * (SCREEN_WIDTH // (block_size + block_gap))for _ in range(SCREEN_HEIGHT // (block_size + block_gap))]# 游戏主循环
running = True
while running:for event in pygame.event.get():if event.type == pygame.QUIT:running = Falseelif event.type == pygame.KEYDOWN:if event.key == pygame.K_LEFT and can_move(-1, 0):update_grid(-1, 0)elif event.key == pygame.K_RIGHT and can_move(1, 0):update_grid(1, 0)elif event.key == pygame.K_DOWN and can_move(0, 1):update_grid(0, 1)elif event.key == pygame.K_SPACE:rot_shape = list(zip(*reversed(shape)))if can_move(0, 0):shape = rot_shapeelif can_move(-1, 0):update_grid(-1, 0)shape = rot_shapeelif can_move(1, 0):update_grid(1, 0)shape = rot_shapeif can_move(0, 1):update_grid(0, 1)else:clear_rows()x_pos = 3y_pos = 0shape = random.choice(SHAPES)color = random.choice([RED, GREEN, BLUE, CYAN, MAGENTA, YELLOW, ORANGE])if not can_move(0, 1):running = False# 绘制背景screen.fill(BLACK)# 绘制方块for i in range(len(shape)):for j in range(len(shape[i])):if shape[i][j]:draw_block(x_pos + j, y_pos + i, color)# 绘制网格draw_grid(grid)# 设置帧率clock.tick(5)# 更新屏幕pygame.display.flip()# 退出游戏
pygame.quit()

这段代码使用了Pygame库来实现游戏的图形界面，通过键盘控制方块的移动和旋转。游戏循环不断更新方块的位置和网格状态，并绘制在屏幕上。在方块达到底部或无法继续移动时，判断是否有满行，并清除满行的方块。游戏会根据方块的状态和移动情况不断更新，直到无法继续下落为止，游戏结束。

请注意，这只是一个简单的示例，可能还有一些功能和优化方面的改进。您可以根据自己的需求进行修改和扩展。
