Train Flow

The platform is packed. The train is waiting.
The crowd on that platform is a picture, and every passenger in it is one pixel. Your train loads one colour at a time.
Drop in a yellow wagon and the yellow crowd rushes aboard, and that patch of the picture empties out. Fill all four wagons and the train pulls out. Another rolls in. Keep going and the crowd thins, block by block, until the platform is bare and every passenger is on their way.
Easy to learn.
Tap a wagon. Watch them board. You'll have it in five seconds.
Then it gets interesting. Every wagon takes an exact number of passengers, and the platform holds exactly enough to fill every one. There are no spare seats. Send in a wagon that can't fill up and it leaves half empty, and the passengers still standing have nowhere to go.
By the tenth level you'll be counting the crowd before you tap.
You'll want one more go
• A brand-new crowd to sort every time
• That perfect click when the last passenger squeezes on and the platform goes quiet
• Chunky, colourful pixel art
• Levels short enough for a bus ride, tricky enough to miss your stop
• No clutter, no filler. You, the crowd, and the train
Load them up. Get them home. Leave the platform spotless.
