Wagons wait in line at the engine shed. Before each one leaves, you may flip one switch; then the wagon rolls along the track and must reach the station of its own colour. Some switches flip by themselves the moment a wagon passes, so plan ahead: the wagon you send now sets the tracks for the ones still waiting.
Never switched a train before?
The first levels show you each idea with a pointing hand and a few words, and new kinds of switches arrive one world at a time: switches that flip by themselves, linked switches, switches you can throw only once, colour sensors, gates, holding loops and stations that want their wagons in order.
150 levels in 7 worlds, plus a new Daily puzzle every day.
Every level is checked by a solver, so there is always a way through, and nothing depends on timing: the board waits while you think.
Play at your own pace. Tap a switch, then tap Go to send the wagon. Undo any move, restart in a tap, and use a hint when you are truly stuck (earn more with three-star levels). Finish with the fewest flips to earn all three stars, and keep your Daily streak going.
Every wagon colour has its own shape, there is a big-symbols option, Railflip speaks English, French and Spanish, and your progress is saved automatically.
