Welcome to our virtual supermarket Supermarket Stack. It opens soon and it's time to put goods on the shelves to fill them completely. You should sort the cans and bags before placing them on the shelves so that the products are not mixed up on the shelves. At each of the ten levels, you need to distribute the cans into piles, each with four cans of the same type. Click on the can and move it to the same one or to an empty space in the Supermarket Stack.
