在龙三角洲，你想要把你的棋子移动到一个像桥一样的木板上，在棋盘的另一边。一件容易的事!或者至少，如果每个人都在一起工作，但你不是。相反，你们每个人都在自己的身边工作，每个人都坚信自己的方式是最好的。

在游戏规则中，玩家同时选择5个动作卡，从9个可用的动作中选出，并将它们按下顺序排列。这个回合一次就解决了一张牌。这些动作允许玩家放置木板，放置木板，移动他们的棋子，取消其他玩家的动作，或者移除木板或基础的石头。正如可以预料的那样，在同时进行操作的设计中，游戏是相当混乱的。

2012年版的游戏,过江龙,包括一个双面游戏板没有出现在早期的版本,与板的一侧有岩石堆,你把石头(原龙δ),而另一边则毫无特色的河在任何位置,玩家可以将石头。

In Dragon Delta, you want to move your pawn over a system of bridge-like planks to the other side of the board. An easy task! Or at least it would be if everyone were working together, but alas you're not. Instead you're all working on your own right next to one another, each convinced that your way is best.

In game terms, players simultaneously select five action cards to be performed from the nine actions available and lay them down in order they are to be played. The turn is then resolved one card at a time. The actions allow players to place plank foundations, place planks, move their pawns, cancel other players' actions, or remove planks or foundation stones. As can be expected for a design with simultaneous action selection, the game is rather chaotic.

The 2012 edition of the game, River Dragons, includes a double-sided game board not present in earlier editions, with one side of the board featuring rock piles on which you place stones (as in the original Dragon Delta), while the other side has a featureless river on which players can place stones in any location.
