在梅森，球员代表建筑师，他们一起在游戏机的景观上建立了城市。当一个城市完成时，所有的玩家得分“公会卡”他们玩，正确的时机玩正确的卡片，使所有的区别。
每一回合，一个玩家首先在板上的某个地方建立一个新的墙壁。每个墙壁将被两个塔包围，并且每个墙壁上都会放置一个房屋。通过将它放在现有的塔旁边，墙可能只需要一个或零个新的塔。如果墙壁沿着游戏板的外侧放置，可能只有一个房子被放置。
放置墙后，玩家滚动三个骰子以确定其中一个塔的颜色（颜色一个可能的第二个塔可以自由选择），两个房子（如果只有一个房子被放置，那么玩家可以选择哪个骰子来挑选房子的颜色）。最后，如果新安置的墙壁使一片土地被完全封闭，建成了一个新城市。如果新城市毗邻一个或多个现有城市，可能会与其中一个城市相结合。城内同色的两座房子升格为宫殿。现在触发得分轮，在此期间所有玩家都可以玩一两个“公会卡”，然后画一张新卡。每个公会卡都会获得刚刚完成的城市或其外的功能。可能的特点是房屋数量指定颜色的宫殿或塔楼，城市的田地数量，“区域”内的房屋数量。在一个城市里面的宫殿数量，一个城市内的颜色不同，或完成城市的总数。在得分回合结束时，无论哪个玩家在最后一个地方都可能会丢弃尽可能多的公会牌，并绘制新的替换它们。
游戏结束时，所有的某些类型的被打了，而获胜者是谁得分最多的。
In Masons, players represent architects, who together establish cities on the landscape of the game board. When a city is completed, all players score points for "guild cards" they play, with the right timing in playing the right card making all the difference. Each turn, a player first establishes a new wall somewhere on the board. Each wall will be enclosed by two towers, and will have one house placed on each side of it. It's possible for a wall to need only one, or zero, new towers by putting it next to existing towers. It's possible for only one house to be placed, if the wall is placed along the outside of the game board. After placing the wall, the player rolls three dice to determine the color of one of the towers (the color of a possible second tower may be freely chosen), and that of the two houses (if only one house is placed, then the player may choose which of the dice to pick for the color of the house). Finally, if the newly placed wall causes a piece of land to be fully enclosed, a new city has been established. If the new city borders one or more existing cities, it may be combined with one of those cities. Two houses of the same color inside the city are upgraded to a palace. A scoring round is now triggered, during which all players get to play one or two "guild cards", and then draw one new card. Each guild card will score a feature of either the just completed city, or outside it. Possible features are the number of houses & palaces or towers of a specified color, the number of fields of the city, the number of houses inside a "district" on the board, the number of palaces inside a city, the different number of colors inside a city, or the total number of completed cities. At the end of a scoring round, whichever player is in last place may discard as many guild cards as desired, and draw new ones to replace them. The game ends when all pieces of a certain type have been played, and the winner is whoever has the most points.
