Lemonade Stand is played over seven turns (days), and each turn players start by turning over a forecast card which shows the weather forecast for the day along with number of customers and the price they will be willing to pay for each possible weather outcome. Players then place a 5, 10 or 15 cent price card down along with any signs or lemonade inventory they want to put out, all face down. All players reveal their cards at the same time and then a new forecast card is revealed which has an arrow pointing to one of five spots on the old forecast card, which determines which weather event occurred. Each player then collects money based on their price and # of glasses of lemonade invested versus the actual weather that happened.

Money is gained or lost, and play continues for seven rounds. Most money wins!
