官方网站都不在了，没看到官方英文规则，把review中的摘出来看
The game is played on a 4x4 board and each player gets 12 gobblets, 3 of each of the 4 different sizes.
游戏在4*4棋盘上进行，每名玩家拿到12个棋子，4种规格大小，每种规格3个棋子。游戏目标是把自己的4个棋子形成一行。
On your turn you can choose one of 4 possible actions:
轮到自己行动时，可以选择下列四种行动之一：
1)Put a new gobblet on the board
1）放一个新棋子到棋盘上；
2)Move a gobblet already in play to any empty space
2）移动一个已在棋盘上的棋子到任意空位上；
3)”Gobble up” any smaller sized gobblet with a gobblet already in play.
3）用一个已在棋盘上的棋子罩住任一个小号棋子；
4)If your opponent already has 3 in a row, you can “gobble up” one of those pieces with a large sized gobblet that is not in play yet.
4）如果对手已经有3个棋子成行，你可以用未放置的大号棋子罩住其中一个对手棋子。
When moving pieces on the board, you only move the top piece, so the gobblet inside it will remain, possibly creating a four in a row. It's important to remember what's been gobbled up. If you touch a gobblet you must move that piece, so no changing your mind.
当移动棋盘上的棋子时，只移动最上面的棋子，被罩住的棋子留在原位。这样可能造成4子一行。所以一定要记住罩住了什么棋子。如果触摸某棋子，必须移动该棋子。
因此楼主的问题，
1、每回合行动一次，棋子的移动或放置位置任意；
2、被罩住的棋子不能移动；
3、只移动最上面一个棋子，下面的都不动。
