German-style games are board games either published in Germany or very similar in style to those published in Germany.

The elements of this style include many of the following:

  1. Multi-player, typically 3 to 6
  2. Game durations of 30-90 minutes
  3. Rules that take 5-15 minutes to explain
  4. Player interaction instead of waiting doing nothing while others take turns
  5. Excellent production values, i.e., visually pleasing and durable components
  6. A satisfying balance of strategy and luck
  7. Fun!
