This exciting and colourful game is designed to develop spatial perception. You can check your solutions using isometric views.

#### Császár polyhedron

The Császár polyhedron is a nonconvex polyhedron with 14 triangular faces.

#### Conic sections

The conic section is a plane curve that is created when a right circular cone is intersected by a plane.

#### Conic solids

This animation demonstrates various types of cones and pyramids.

#### Cube

This animation demonstrates the components (vertices, edges, diagonals and faces) of the cube, one of the Platonic solids.

#### Cuboid

A cuboid is a polyhedron with six rectangular faces.

#### Cylindrical solids

This animation demonstrates various types of cylindrical solids as well as their lateral surfaces.

#### Euler's polyhedron formula

The theorem formulated by Leonhard Euler describes one of the basic properties of convex polyhedra.

This special concave polyhedron was named after a Hungarian mathematician.

#### Solids of revolution

Rotating a geometric shape around a line within its geometric plane as an axis results in a solid of revolution.

#### Solids of revolution (rectangle)

Rotating a rectangle around its axes of symmetry or around its sides results in solids of revolution.

#### Sophie´s desk

A game about the different views of complex objects.

#### Sphere

A sphere is the set of points which are all within the same distance from a given point in space.

#### Volume of a tetrahedron

To calculate the volume of a tetrahedron we start by calculating the volume of a prism.
