Welcome to our cafe, where the main and main dishes are donut sort donuts. Visitors are offered an unusual dish- these are four donuts written on a vertical axis. The upper donut is decorated with a berry. All donuts in the stack should be the same. Your task is to sort and form ready-made dishes, dragging donuts from one axis to another, until the goodies of the same color appear on each. Donuts can move in groups if there were the same in Donut Sort nearby.
