The program "Jahresarbeit 2003" was created as an annual work in the subject of computer science. After starting the game you will see a 9x9 field with different coloured squares. Arrows can be seen at the edge of the field, which are used to move the rows and columns in which the squares are located. Connected squares of the same colour form an area which can be removed by clicking on it. The aim of the game is to remove areas as large as possible in the shortest possible time. The game is over when all squares have been removed or there is no longer any way of removing the remaining squares. However, you should use as few clicks as possible to remove all squares, as these will reduce the final score.
