## 4-levels number puzzle (ZueleRaetsel). |

Description: Numbers calculation game, where the three numbers being part of a mathematical operation (actually an addition)
are represented by 3 shapes of different shape type or/and different color. The aim of the game is to find out which number hides behind the different
shapes.

The game comes with 4 levels, the first one, with elementary calculations, intended for young children. Level 2 and 3 are somewhat more difficult, but
should be adequate for children of the first years of primary school. At level 4, the shape rows represent equations in 2 or 3 variables and thus may
mostly be to difficult to solve without the mathematical knowledge of how to solve 1st degree equation systems.

To note, that changing the level only takes effect with the start of a new puzzle.

Free Pascal features: Manipulating shapes: Showing or hiding them as needed, changing their position, shape type and brush
color.
