In the new online game Box Stacker, you will have to build a high tower. Before you on the screen will be visible a platform that will swim in acid. Above it at a certain height, cubes will appear that you can move to the right or to the left, and then throw it to the platform. So gradually throwing cubes you will build a high tower and get glasses for it. Remember that if at least one cube falls into acid, you lose in the Box Stacker game and start the passage again.
