In Mini Metro, subway stations appear on a blank map, and players drag lines between them to keep up with demand. Players can’t control where stations appear, only reroute tracks to serve them better and add new trains or carriages as the game allows.
The action builds slowly, as stations pop up and passengers begin to appear at them, board the little gliding trains, and disembark at stations further down the line. Most of the game is spent watching and gently tweaking — that’s the zen part — but when passengers pile up, the hectic nature of the game takes over. The game is lost when a station gets too crowded.
The minimalist game offers 13 different maps, representing cities from Cairo to New York to a fictional Auckland system, each with unique features.
