Donnerloch

Players try to buy lots on the game map. Lots will in urn bring the revenues. The lots that pay out are determined by dice.
In the first phase, every player gets one lot for free
In the second phase players can buy additional lots, using the revenues as money.
In the last phase of the game, the lots pay dividends, but every turn there is a high chance that one random lot becomes worthless (i.e. contains a "Donnerloch").
Players win when they buy certain combinations of lots or -if no one is able to - have the most money at the end.
