Vilac L'Habilrinthe skill and strategy game

L'Habilrinthe is a 2-in-1 marble game: On one side, you can tackle three courses of increasing difficulty by manipulating the two sliding handles to guide the marble between the holes without letting it fall. On the other side, there is another labyrinth game that you must navigate by tilting the L'Habilrinthe in all directions to direct the marble. It starts off quite easy, but can you make it to the end? Size: 33 x 16 x 5 cm, includes 3 steel marbles.
