Witch Market

From BoardGameGeek:

You are a witch in the stock market and you must use your magic and ingenuity to obtain more money than your opponents. Witch Market is a no language dependent, family-friendly filler where players must buy or sell ingredients from the market at the most opportune times. Buy: To take all the ingredients of the same color from the market for Free! You know... using magic. Sell: Discard from your hand all the Ingredientes of the same color and get coins for them! This is how you win! The value of each sold Ingredient will be equal to the number of ingredients of the same type sold on the Market! So plan your sales wisely. Get rewards for being one of the fastest sellers! Sometimes selling first is better than selling a lot, so time your sales to get coin rewards. But don't be greedy! At the end of the game, each ingredient that is still in your hand will subtract 2 coins! So try to take the necessary Ingredients and sell them in time. Witch Market is a game of 20 minutes, where each movement will modify the Market and the decisions of all the witches. Can you be the wealthiest witch? Or will your greed win you over? —description from the designer
