mini-metro game sourced
Mini Metro
A minimalist subway-design game where the player draws and redraws lines between shape-coded stations under a weekly ration of trains and tunnels until a station overcrowds.
core loop
new stations appear -> draw or reroute lines -> trains carry shape-matched passengers -> weekly grant of new assets -> demand outgrows capacity -> a station overcrowds and the run ends
design notes
Mini Metro abstracts a metro network into station shapes, passengers drawn as the shape of the station type they want to reach, and a scarce inventory of lines, locomotives, tunnels, and bridges. New stations keep appearing while supply arrives only as a weekly grant, so the player keeps redrawing a network that is always under capacity. Failure is local and visible: a station over its limit (typically six passengers) for long enough ends the run. Modes vary the rules: Extreme fixes lines once placed, Endless removes overcrowding, and Creative is a sandbox.

5 stored edgesPublic transit lines
The player draws colored lines between stations and assigns trains that load and unload automatically; ridership is the score.
Service queues
Passengers wait at stations with limited capacity, typically six; interchanges raise capacity and loading speed, and a station overcrowded too long ends the game.
Agent pathfinding
Passengers ride to any station of their target shape, transferring between lines when needed.
Periodic ticks
Each in-game week grants extra rolling stock and a choice of assets such as tunnels, bridges, new lines, or interchanges.
