At the beginning of each round, the Route dice are rolled once. The results of the roll will determine which Routes all players must draw that round. After the roll, all players play simultaneously, drawing the Routes rolled on their own boards.
Stations allow you to connect a Railway Route to a Highway Route. Overpasses allow the two to cross without being connected to each other.

Volcanoes start erupting, but the Route building must go on! Work your way around lakes of Lava and prevent them from destroying your Routes! Confine the Lava streams to gain extra points: at the end of the game, you get 5 points for each Lava lake without open sides, and you also get 1 point for each space occupied by your Largest Lava lake (even if it is not closed). But remeber: open Lava lake sides count as Errors at the end of the game.

Meteors will wreak havoc and destruction, but they also bring precious minerals and ores to Earth. 1 Meteor will hit each round, creating a Crater on your Board and destroying any Route it hits. At any point during the round, you can erase a Crater to draw a new Route in its place. But, if you lead Routes into the Craters, at the end of the game you can gather precious resources and gain additional points!
