Users operate a lemonade stand in order to make a profit and win the game.
The site uses yellow text on a black background that makes it difficult to read for long periods of time. The concept of the game is fairly simple. Each day the user must decide how many cups of lemonade to make based on the weather forecast. The game continues until users have no more money, decide to retire or reach 25 game days. Because the game is fairly simple even younger students could probably grasp the idea behind it, making it a good candidate for a math lesson for elementary teachers.
