Title: Question about river U-Turns (WICA vs Asmodee app)
Post by: corinthiens13 on May 25, 2021, 11:22:30 PM
Hi everyone,

WICA says:

You cannot make a river turn twice in a row in the same direction (a U-turn), as this risks that the following tile will be impossible to place

And also:

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.

This seems quite clear. On the picture below, I did always play that A and C are allowed (they're not direct u-turns), but B and D are forbidden (direct u-turns).

But asmodee's mobile app forbids situation A too and allows B, C and D. No matter the situation, the app doesn't allow the river to go back in the direction of the river source (see screenshot, the last tile shown can only be placed to make the river go down, it can't be placed so that the river go back up).

Is this an unofficial restriction used by asmodee that you cannot make direct u-turns AND you cannot make the river go back in direction of the source ?

This is an additional limitation by Asmodee in order to avoid any possible problems that may lead to an incomplete river.

If you check the following image from WICA, example A is taken from the rules by HiG. So HiG allows non-immediate U-turns although the Asmodee App excluded this possibility.

Rules on any app are always secondary to the actual rules. Apps have to make some  minor changes for the sake of convenience.

Sometimes they also provide some clues... like for example when combining the Gingerbread Man with Expansions 1, 2 and 3...  ;)
