what happens if you reach more points than are on the board?
You use the "50" points tile and then go on to 1, 2, 3, etc. as usual. If you don't have the 50 point tile from I&C (I think), you'll have to use something else to help you remember that that player has got more than 50 points. At the end of the game, just add the 50 to the current score on the scoring track.
Alternatively, you can print out the scoring track found in the
Public Downloads.
if you have 4 tiles to a completed road and a thief on each of the four tiles does that count as 16 points?
The answer depends on the colour of the thieves. If it was 4 RED thieves, then RED would get 4 points. If it was 3 RED thieves and 1 BLUE thief, then red would still get 4 points. If it was 2 RED thieves and 2 BLUE thieves, then RED would get 4 points
and BLUE would get 4 points.
However, it would be hard to get a thief on each of the 4 tiles. Remember you can't put a thief on a road that already has a thief. However, you can put a thief on the "end" of a road and a thief on another "end" and connect them together with a tile. In which case, there are 2 thieves on a 3 tile road. Again, if the thieves are the same colour, then the player who owns both scores 3 points. If there is one of each colour, then both player scores 3 points.
I hope that helps.
