Focus Rail is a free train-routing puzzle for Android. You flip track switches so each coloured train reaches the station with its colour. New trains keep entering the board, so you watch several routes at once and plan one switch ahead. There are 12 lines to work through, and nobody has cleared the last one yet.
I made Focus Rail on my own in Nairobi, and it is my first released game. The trains are small 3D models that turn with the track. That keeps the board readable when it gets busy. It is free, with a daily lives limit, optional rewarded ads and optional coin packs.
