In German, the term "dunkelflaute" refers to a period in which energy demand is high but electricity production is low, as in winter on windless days with little sunlight. This expression underlines the importance of planning and diversification in our energy mix.
Dunkelflaute is a competitive game in which players try to build a resilient energy park to guarantee sufficient electricity production on each turn. To achieve this, players must invest wisely in different energy sources and allocate their budgets to maximize production while limiting risk.
On each round, players have three discs of different values to allocate to three different purposes: to purchase new tiles for their park, to purchase new houses to power, and to purchase dice to be used that round. Players then roll the dice and try to place them on the tiles they've bought to power the houses they've purchased. The number of houses a player has managed to power in his park will determine the value of his discs for the following round, and so on until a player ends the game by buying a twelfth house. The round then ends as normal, and the player who has powered up the most houses wins the game.
