The Three Marbles

The objective is simple : each marble must go into the place which it corresponds to.

The icy marble go in the icy place, the fired marble go in the golden place and the green marble go in the green place.

To succeed to this mission, you must :

1-identify the colour,

2-direct the grey lego ensemble,

3-make the marble roll to his place !

I hope you will like the idea,

Mr Brick.
