Metro Sofia is a finite incremental about building the real Sofia subway system from 1998 to 2026, one station at a time across four lines. You ring bells to accumulate riders, unlock stations with the currency you earn, and gradually illuminate the city map while learning facts about each real neighborhood you reach. It's designed for players who want a calm, goal-oriented experience with a definite endpoint and optional sandbox play afterward, featuring no ads or prestige mechanics.

About this game

A calm, finite incremental game about the Sofia metro. You start in 1998 with three stations at Serdika and a single train. Ring the bell, carry riders, and dig the real line outward one station at a time - Vardar, Lyulin, Slivnitsa, then Mladost, the second diameter, the airport and Business Park branches, the third diameter and the 2026 extension to Levski. Every station is a real place, with its real name, its opening year and a fact worth knowing. The city sits under a dark veil and lights up wherever your trains reach. Each era opens with its own card, drawn from your own network. Finish the plan, then keep going - the districts Sofia never reached are waiting.
