Buy Upalu Mundi PC key

Upalu Mundi is a transport-network puzzle game set in a dwarven world reshaped by the invention of the locomotive. You play Pyrael, a trolley-cart network engineer at Mountain Mining Industries, E.C., and shape the world as the company expands into new regions. Its self-contained levels use an 8x8 grid and limited rail-switching logic, with multiple deterministic solutions to each puzzle.

Design and test networks

You lay tracks, build stations and direct trains with switches. The network uses four switch types once used for trolley carts in the mines. Before putting a design into service, you can validate it on a simulation device: push the throttle and watch miniature trains travel around the layout on a model kit.

Optimize your layouts

Each level has an optimal line revealed by the Upalu Mundi, an iridescent gem that seems to hold the knowledge of the world. You refine your blueprints through experimentation to bring your network in line with it.

Follow the consequences

Your decisions ripple through the world. Newspapers report on their consequences, and company meeting minutes share what your coworkers have to say about your new look and other agenda items.
