In a fantasy world shaken by the invention of the locomotive, you assume the role of Pyrael, a trolley cart network engineer at Mountain Mining Industries, Inc. As the company expands its operations across the world, you are in a unique position to shape the world around you.

Upalu Mundi draws inspiration from the challenges of efficiently connecting producers and consumers in open-ended transport games, but uses limited rail-switching logic on a neatly arranged 8x8 grid to offer self-contained puzzle levels with deterministic solutions. While initial solutions are generally easy to discover, unique strategies are essential to achieving optimal results.

Original Design - Lay tracks, build stations and control the flow of trains using switches. The R&D department is hard at work to invent more sophisticated train routing. In the meantime you'll have to make do with the 4 types of switches that the company used for trolley carts in the mines.

Orderly Simulation - Before commissioning a transport network, the design must be tested on a simulation device. Push the throttle and watch your creation materialize as the trains make their rounds on the model kit.

Open-Ended Puzzles - After getting the first working blueprint, see how it compares to the optimal line set by the mysterious workings of the Upalu Mundi, an iridescent gem that seems to contain humanity's knowledge.

Organic Storytelling - Read about the consequences of your actions in the world’s rich newspaper landscape, and skim through the company’s meeting minutes to catch what your coworkers are saying about your new look and any other important topics on the agenda.

Obligatory Solitaire - Shift around some blocks to relax, then work some more.
