In the electronic 'pocket' version of Ticket to Ride: Europe, I would like to acquire all the achievements, but I must have misunderstood some of them. Even when I think I've accomplished them, I do not get them. In particular:
"win while connecting all 4 surrounding countries"- which 4 countries are we talking about, surrounding what? Each other? Like Austria, Hungary, Italy and Croatia e.g.?
"win without claiming any tunnel route". I've won many times without using a single tunnel, but still no achievement. A route can be finished with or without tunnels, but does this requirement mean that when I get the map, there is no possible tunnel involved between the two cities?
