In Lemonade, the player begins with $1 to start a lemonade stand. The goal is to make the most money possible selling glasses of lemonade over the course of several days.
The player has to contend with:
- changing temperatures and weather conditions, which impact the number of glasses sold
- random increases in the cost of key ingredients
Lemonade has been described as a simple game, but "what it lacks in depth it makes up in being just plain fun." 
Lemonade was first released by Tom Wildoner of T&J Software in Aug. 1990.
