For first edition rules follow here: River.
General info and comments
The River modifies the beginning of the game by having players place a set of specific river tiles before the normal tiles.
- 12 river tiles, each with with a dark back, which replace the start tile
The River contains 12 river tiles, each with with a dark back, which replace the start tile. Set aside the source and lake tiles.  Shuffle the remaining river tiles and stack them facedown. Add the lake tile to the bottom of the stack, and place the source tile faceup as the starting tile.
Preparation of River II
River expansion added to Count, King and Robber includes a river fork tile. It should be set aside along with the source and lake tiles. The fork tile is to be placed first (after the source tile) by the first player.
Playing the game
Placing a tile
You draw a river tile and place it in a way that its edges match the edges of tiles already in play. However, the river cannot turn in the same direction twice in a row, as this risks that the following tile will be impossible to place.  Players must draw and place all river tiles before they can draw normal tiles.
Placing a meeple
Like any other tile, you may place a meeple on other features of a river tile you just placed.  Meeples cannot be placed on the river itself.
If you place the last River tile (the lake with the volcano), you cannot place a meeple on that tile. Immediately after placing it, take another turn by drawing a normal tile.
The River feature itself cannot be scored. All other features on river tiles are scored as usual.
Note on River II special features
The inn and the volcano on the River follow the rules from their expansions (Inns and Cathedrals and The Princess and the Dragon, respectively). The pigsty has the same effect as a pig in a field (from Traders and Builders). If you are playing without these expansions, simply ignore these features.
Clarifications for new landscape tiles
The following tiles do not split farms - there is one farm on each tile
Farms do not go under small bridges - there are 4 separate farms here
and three farms here, one north and two south.
While this big bridge does not separate farms. There are two farms here - one eastward and one westward.
Total tiles: 12

- You can combine The River II with The River from base game to make a very long river. You can even mix multiple River sets. Keep one lake tile for each source and additional one for every fork tile.
- Question: With the U-turn rule when making rivers, does that mean no U-turn ever, or just no immediate U-turns because it will complicate the placement of subsequent river tiles? Answer: Only immediate U-turns are explicitly forbidden. Naturally, there can also be problems if a straight river tile lies between. Turning river the same way three times should also be considered prohibited.
- Note that river segments separate farms. (08/2014)
- That means you cannot execute any other action that turn.
