Railroad Ink: Deep Blue Edition

In Railroad Ink™ you have to draw these routes on your erasable boards to create transport lines and connect your exits, trying to optimize the available symbols better than your opponents. The more exits you connect, the more points you score at the end of the game, but you lose points for each incomplete route, so plan carefully! Will you press your luck and try to stretch your transportation network to the next exit, or will you play it safe and start a new, simpler to manage route?
