玩法简介：
1. 一只一担是流传在中国米黄玉之乡的谭山镇的一种双人、益智、棋牌类游戏。棋盘是4*4的方格线，棋子放在线与线的交界处。棋子可以用任意两种可以区分的道具，如纸团、石子、木棍等。因此随时随地，只要在地上画个4*4的方格，弄几个石子什么的就可以玩了，非常的方便。
这个游戏分为两个阶段——谋篇布阵和征战。
刚开始，双方在棋盘上抢占有利位置，并互相征战。棋盘上位置占满后，一方弃掉自己的一个子，棋盘上就有空位置了，双方就开始交替移动棋子，进行征战，没有可以移动的棋子时，弃掉自己的一个棋子，轮到对方走棋。直到最后一方没有棋子了结束战斗。
吃子规则
两个（一担）可以吃掉对方的一个或者两个（一担）。具体图形如下（A——甲方，B——乙方，O——空位置）：
1. AABO——甲由?ABO，在第一个位置走一个棋后变成AABO；或者由A?BO，在第二个位置走一个棋后变成AABO。则第三个位置的乙方棋子被剔除棋盘，变成空位置，再由双方来争夺这个位置。
2.OAAB——甲由OA?B，在第三个位置走一个棋后变成OAAB；或者由O?AB，在第二个位置有一个棋后变成功能OAAB。则第四个位置的乙方棋子被剔除棋盘，变成空位置，再由双方来争夺这个位置。
3. AABB——甲由?ABB，在第一个位置走一个棋后变成AABB；或者由A?BB，在第二个位置有一个棋后变成功能AABB。则第三和第四个位置的乙方棋子都被剔除棋盘，变成空位置，再由双方来争夺这个位置。
其他的情况不可以吃棋。如以下两个图形。
1. AABA
2.AAAB
通常用这两种棋来防守，防止对方吃掉自己的棋子。
