There are three objects of different sizes in the smart tower competition, let's call them SMALL, MEDIUM and LARGE. There are also three areas. The game is started with all the objects on top of each other at the top of the left, then from bottom to top: large, medium and small. The object of the game is to get the same formation to the right area. Objects may be moved one at a time and a larger object must not be placed on a smaller one.
So how's the competition going? Each team has its own objects and its own areas. The teams are 15 meters away from their areas, and when the kick-off sounds, the first player runs to the objects, makes the first move (raises the top object to either the middle or right area) and runs back. Then the next player goes and makes the next move. The game lasts until the first team gets the starting formation to the right. There are 4 sets of objects in the set, so 4 teams can play at once.
