From the website:
Passtally is one of those rare games that is a snap to teach and learn but holds staggering depth and nuanced decision making and strategy. Players compete by strategically placing titles in the hopes of creating the cleverest connecting route, which is far from easy. Titles can be stacked to alter existing routes and add victory or chaos to existing structures. The higher the stack, the greater the points for that tile—just make sure the points are only belong to you!
As you continue, the game becomes increasingly visually striking as the colors stack and combine. How high can you stack?!
