Pixel Jam Bus Puzzle

Pixel Jam Bus Puzzle is a sorting puzzle where the pieces are vehicles and the pictures are made of passengers. A bus takes on passengers of its colour, and a full one leaves and frees the space it was parked in, so the constraint is parking rather than time. Each picture is cleared by matching colours to the passengers waiting for them, and the order matters because capacity is finite: a bus that leaves half full has used a space for nothing. There are a thousand levels, with difficulty climbing and the occasional easier stage to break it up. Clear and Shuffle are there for the boards that go wrong, pickup speed can be upgraded, and the helpers sit on screen. It plays with a mouse or by touch, in portrait or landscape, and progress is saved in the current browser.
