You know those really clean subway maps, with solid colors and minimal distractions (like these)? Have you ever wanted to design one for yourself, perhaps even create your own route so you can get to work faster? If so: Read on. If not: You’re about to change your mind.

Welcome to Mini Metropreviously known as “Mind the Gap” when it began during Ludum Dare 26 in 2013. Developed by New Zealand studio Dinosaur Polo ClubMini Metro is so astonishingly fun and addictive that you won’t be able to look at a subway map the same way again.

Released early last month, Mini Metro is a minimalist puzzle game that revolves around building your own subway system in regions based on real-world cities. With surprising depth added to top-down puzzle-game conventions, Mini Metro is like the next generation of Trainyard or Flow. The objective is simple: Get passengers to their destinations by helping them reach their respective shape, with each happy passenger equating to a point. It starts easy, with a small handful of locations and passengers, but soon turns into a frantic race of strategy and coordination as the city rapidly grows and station platforms become overcrowded with impatient travelers. Open more routes, give your rapid transit vehicles RPG-like upgrades, and plot ahead with quick-thinking to make high scores and ultimate find ultimate self-satisfaction in all those happy passengers.

As with the alpha and beta releases, the full release of Mini Metro has been receiving frequent updates tweaking performance and aesthetics. Dinosaur Polo Club have been transparent in their development process, and even host a public Trello board to show what is at the top of their to-do list.

Mini Metro is available now on Steam and Humble Store for $10, and will be available on mobile in the future. Check back soon for our review of the PC version.
