How to play

The rules, the screen during a level, and the pause.

The rule

Guide each train to the station that shares its color. Tap a glowing switch to change the track a train will take, and set it before the train reaches it.

The screen during a level

• The clock, and the trains delivered out of the target, such as 9 of 14.
• Your lives, as hearts.
• From three deliveries in a row, your streak.
• The next trains leaving the depot.

Lives

A wrong station or a dead end costs one life. The level ends when none are left (Out of lives) or when the clock runs out (Time's up). Only trains delivered to their own station count toward the target.

The bonus round

Reach the target before the whistle and the rest of the clock is a bonus round: deliveries score double and mistakes cost nothing. See The bonus round.

Pause

The pause button stops the level. Resume, Restart level or Quit; during the bonus round, Finish — keep the win. Leaving the app also pauses the level.

The results

At the end: your score, the trains delivered, your mistakes and your stars, then Next level, Retry or Home.
