This application is an introduction to learning programming. During the game, the arrangement of the green jellies on the left side should be shown symmetrically on the board on the right side. On the right board, jellies are added simply by clicking on the selected field or by moving your foot or hand over it. Finally, check your alignment with the “magnifying glass” button. Will you be able to position the jellies flawlessly? There are three levels of difficulty, differing in the number of elements to be mapped.
