The Basics
In The Quacks of Quedlingburg, each player takes the role of one of the quacks - fake doctors at a fair, trying to brew the biggest, foamiest potion to win the prize.
Each player has a large cauldron in which they place ingredients they randomly draw from their bag. Chunks of pumpkin, berries, bugs and some spooky extras all add up to grow the potion, earn more points and money to buy more ingredients for the next round.
But watch out for the white ingredients. These little berries make your potions foam and bubble beautifully - but if you ever have too much in your cauldron, it explodes and you'll lose out on points or money this round.
