Stack Sort Trip

Welcome to Stack Sort Trip! Tap a bus to send it to a column. Each new bus pushes the others down, sending the bottom bus to the waiting area. Buses drop off passengers of different colors and pick up passengers that match their own color. Once a bus is full of matching passengers, it leaves! If a bus isn't complete, send it to another column and keep sorting. Choose your columns carefully, manage the waiting passengers, and complete all the buses to finish each level. Simple to play, but every move matters! Can you sort them all?
