I don't know how to interpret the control of a world rules.
The control of a world comes in play in 3 different ways.
1) when determining the action points (+1 if you control your world in a 3 player game)
2) during the world power phase
3) during scoring (+5 points for every world you control)
In the world power phase as in the scoring phase controlling means that a player must have the strict majority out of 5 stones in a world to control it.
Does this mean that for determining the action points that there must be 5 stones in your home world and you must control it (have the majority) in order to have access to the additional action point ?
Thanks for your help.
Control means that you have the majority of stones on there. At the start, for instance, each player has 1 stone on their home world. Therefore, they have control.
You get to use a world power if there are 5 stones total on a world and you have the majority.
For scoring purposes, it's the same as at the start. If you have a majority, no matter how many stones are in the world, you get 5 points.
Hope that clears things up.
