Lines on game tiles

Yellow Lines

Each yellow line that divides two spaces is marked with an arrow that points in one direction. Crossing a yellow line against the direction of that arrow costs 3 spaces of movement. Crossing a yellow line with the direction of that arrow costs the usual 1 space of movement.

Spaces divided by a yellow line are considered adjacent to one another.

Red lines

Mice cannot move from one space to another if they must cross a red line to do so. Spaces divided by a red line are not considered adjacent to one another.
