I just preordered the new titan game, and my only concern was being able to figure out the flow of the board... you have solved that problem, thank you. I shall now favorite this shot
Once a stack starts moving it will pretty much follow a path, but the initial movement depends upon where the stack starts from.
On the outer ring, movement follows the other ring in a clockwise direction, unless the stack started on a spot that allows movement up into the middle ring.
On the middle ring, once movement starts, it goes in a counter-clockwise direction that sort of weaves. There are some spots that if you stop on them. Your next movement is forced to go down to the outer ring.
That all sounds more confusing that it is, and most people pick up the movement fairly quickly.
I like the overlay. It sort of gives the board a 3D look with he mountains and tundra at the top of a cone. I always fancied crafting such a board as you sort of get drawn down to the outer ring.
