Onder de Hamer ("Under the Hammer") is an auction game. The goal of the game is to develop a project as cheap and fast as possible. The projects are famous buildings in Rotterdam, including the Cubic Houses, the Euromast, the Kuip, Erasmus bridge, and the Erasmus University. The projects require different types of investments, like raw materials and employees. The investments can be obtained by bidding in an auction. There are six different auction types/systems in the game. The game has to be played with four or five players, or can be played in teams. The first player who develops his project is the winner of the game. —description from the rulebook
