I don`t understand. When i move one step forward through one of five roads, for example from 6 to 7, i also move one step forward through scoring track with little piece of mine?
If so what will happend if i have just one piece on board and move from -4 to -3, because on scoring track there are no negative positions?
No, you don't score for the numbers printed on the board during game. During game you only score for the number tiles you step onto. Only in the end of the game do you score for the numbers printed on the board (depending on your markers' position) and the stones collected.
