Please find below more questions posted on WICA. This time, they are related to the interactions of
The Labyrinths and the Builder (Exp. 2 - Traders & Builders):
[Q1] Does anyone have rules for mixing Labyrinths with the 2nd Expansion?
[Q2] Can I put a builder on a Labyrinth road segment?
[Q2.1] If I can what happens if I finish a road segment but not the Labyrinth?
[Q2.2] My builder and my meeple has stay on that road segment until the whole Labyrinth is finished?
[Q2.3] And even if I can't put a builder next to a Labyrinth road, what if I connect the Labyrinth to a road which already has a meeple with a builder?
There is no official rules covering this interaction as HiG stopped providing clarifications involving minor expansions in 2016. So haw can we address this? My line of thought is the following: The labyrinth tiles behave like roundabout road segments with special rules for meeple placement and, in the case of the advanced rules, an additional bonus.
So, if we separate concerns, a labyrinth is basically a road segment at its core. Thus, you can place a builder as usual on it or any of the roads branching out from it, affecting the whole road network:
* You will get a double turn when extending any road branch connected to a labyrinth tile.
* You will get your builder back when all the branches of a road network containing labyrinth tiles are completed.
So getting back to the questions:
[Q1]: There are no official rules for the interaction of The Labyrinth and Traders & Builders.
[Q2]: Yes, you can place a builder on a labyrinth if you already placed at least one of your meeples on any road connected to the labyrinth, that is, you comply with the requirements to place the builder on any regular road.
[Q2.1] You may complete one road branch but the entire labyrinth road network will not be completed until all its branches are completed too. This would be the same as a road with a roundabout. So you will get double turns any time you extend any of the branches but scoring won't happen until the road network is fully completed.
[Q2.2] Yes, all the meeples and builders on a labyrinth road network will stay on the feature until it is completed, the same as for any regular road.
[Q2.3] If a road with your builder gets connected to a road network with a labyrinth, your builder will affect the whole road network.
In a nutshell, labyrinths are just special roundabouts. The builder will behave as usual on a road network contains labyrinth tiles or not.
