The mercury must be manouvered to fill as many holes as possible in the Eiffel Tower, without the mercury going out of play by falling to a lower level on the left of the puzzle. The item was made in France and the rules on the back are in both French and English. A number of players can be involved, the winner being the person who fills the most holes with mercury. The item can equally well be treated as a dexterity puzzle.
