1、2048
1. 游戏简介
2048 是一款比较流行的数字游戏。游戏规则：每次可按上、下、左、右方向键滑动数字，每滑动一次，所有数字都会往滑动方向靠拢，同时在空白位置随机出现一个数字，相同数字在靠拢时会相加。不断叠加最终拼出 2048 这个数字算成功。
2048 最早于 2014年3月20日发行。原版 2048 首先在 GitHub 上发布，原作者是 Gabriele Cirulli，后被移植到各个平台。
本例难度为初级，适合具有 Python 基础和 Pygame 编程知识的用户学习。
2. 设计原理
这个游戏的本质是二维列表，就以 4*4 的二位列表来分析关键的逻辑以及实现。二维列表如下图：
所有的操作都是对这个二维列表的数据的操作。分为上下左右四个方向。先说向左的方向(如图)。 向左操作的结果如下图；当向左的方向是，所有的数据沿着水平方向向左跑。
水平说明操作的是二维列表的一行，而垂直操作的则是二位列表的一列。这样就可以将二维列表的操作变成遍历后对一维列表的操作。向左说明数据的优先考虑的位置是从左开始的。这样就确定了一维列表的遍历开始的位置。
上面第 2 个图共四行，每一个行都能得到一个列表。
list1：[0,0,2,0]``list2：[0,4,2,0]``list3：[0,0,4,4]``list4：[2,0,2,0]
这样一来向左的方向就变成。从上到下获得每一行的列表，方向向左。参数(row,left)。 其他的三个方向在开始的时候记住是怎样获得以为列表的，等操作完才放回去这样就能实现了。

2、贪吃蛇
1. 案例介绍
贪吃蛇是一款经典的益智游戏，简单又耐玩。该游戏通过控制蛇头方向吃蛋，从而使得蛇变得越来越长。
通过上下左右方向键控制蛇的方向，寻找吃的东西，每吃一口就能得到一定的积分，而且蛇的身子会越吃越长，身子越长玩的难度就越大，不能碰墙，不能咬到自己的身体，更不能咬自己的尾巴，等到了一定的分数，就能过关，然后继续玩下一关。
本例难度为中级，适合具有 Python 基础和 Pygame 编程知识的用户学习。
2. 设计要点
游戏是基于 PyGame 框架制作的，程序核心逻辑如下：
游戏界面分辨率是 640*480，蛇和食物都是由 1 个或多个 20*20 像素的正方形块儿(为了方便，下文用点表示 20*20 像素的正方形块儿) 组成，这样共有 32*24 个点，使用 pygame.draw.rect 来绘制每一个点；
初始化时蛇的长度是 3，食物是 1 个点，蛇初始的移动的方向是右，用一个数组代表蛇，数组的每个元素是蛇每个点的坐标，因此数组的第一个坐标是蛇尾，最后一个坐标是蛇头；游戏开始后，根据蛇的当前移动方向，将蛇运动方向的前方的那个点 append 到蛇数组的末位，再把蛇尾去掉，蛇的坐标数组就相当于往前挪了一位；如果蛇吃到了食物，即蛇头的坐标等于食物的坐标，那么在第 2 点中蛇尾就不用去掉，就产生了蛇长度增加的效果；食物被吃掉后，随机在空的位置(不能与蛇的身体重合) 再生成一个；通过 PyGame 的 event 监控按键，改变蛇的方向，例如当蛇向右时，下一次改变方向只能向上或者向下；当蛇撞上自身或墙壁，游戏结束，蛇头装上自身，那么蛇坐标数组里就有和舌头坐标重复的数据，撞上墙壁则是蛇头坐标超过了边界，都很好判断；其他细节：做了个开始的欢迎界面；食物的颜色随机生成；吃到实物的时候有声音提示等。

3、俄罗斯方块
1. 案例介绍
俄罗斯方块是由 4 个小方块组成不同形状的板块，随机从屏幕上方落下，按方向键调整板块的位置和方向，在底部拼出完整的一行或几行。这些完整的横条会消失，给新落下来的板块腾出空间，并获得分数奖励。没有被消除掉的方块不断堆积，一旦堆到顶端，便告输，游戏结束。
本例难度为高级，适合具有 Python 进阶和 Pygame 编程技巧的用户学习。
2. 设计要点
边框――由 15*25 个空格组成，方块就落在这里面。
盒子――组成方块的其中小方块，是组成方块的基本单元。
方块――从边框顶掉下的东西，游戏者可以翻转和改变位置。每个方块由 4 个盒子组成。
形状――不同类型的方块。这里形状的名字被叫做 T, S, Z ,J, L, I , O。如下图所示：
模版――用一个列表存放形状被翻转后的所有可能样式。全部存放在变量里，变量名字如 S or J。
着陆――当一个方块到达边框的底部或接触到在其他的盒子话，就说这个方块着陆了。那样的话，另一个方块就会开始下落。

4、连连看
1. 案例介绍
连连看是一款曾经非常流行的小游戏。游戏规则：
点击选中两个相同的方块。 两个选中的方块之间连接线的折点不超过两个(接线由X轴和Y轴的平行线组成)。 每找出一对，它们就会自动消失。 连线不能从尚未消失的图案上经过。 把所有的图案全部消除即可获得胜利。
2. 设计思路
生成成对的图片元素。 将图片元素打乱排布。 定义什么才算 相连(两张图片的连线不多于3跟直线，或者说转角不超过2个)。 实现 相连 判断算法。 消除图片元素并判断是否消除完毕。
