â–¶ Play Understreet Express now

Below the city runs the older line, where the understreets rearrange themselves in the dark. Rubble sprouts on the rails wherever the train feasts on light. The deep line grew teeth; only patient drivers bring their strays home.

How to play

1. Steer the engine with the arrow keys, swipe, or the on-screen pad.
2. Couple strays to grow — every few pickups, new rubble falls onto the rails.
3. Touching a wall, your carriages, or any rubble ends the run.
