One tap flips the track
Each switch is a green, glowing junction on the board. Tap it and the track bends the other way. The trains follow the rails on their own: your only job is to set the switches.
A station only accepts the train of its color. Send a red train to the blue station and it costs you a life.
Plan ahead
When you tap a switch, the route it opens lights up, all the way to the station the next train will reach. Set each switch before the train arrives: what you see lit is what the train will do, even if you tap just before it reaches the junction.
At the top of the screen, a row of small trains shows the next ones leaving the depot, in order. Read it to set the board one move ahead.
What costs a life
- A train delivered to a station of another color.
- A train sent into a dead end, with nowhere to go.
Trains never crash into each other. See How to play.
