From Last Day of Work:
Plant Tycoon sets players on a journey to create a virtual nursery of wildly diverse plants, cross-pollinating numerous varieties along the way to discovering the genetic codes for four magical plants. To finance the research necessary to pollinate and harvest the four magical plants, players must sell their discoveries along the way to earn the financial resources vital to acquiring special enhancements-such as exotic seeds, soil upgrades, radioactive plant food, and Insta-Grow fertilizer. Unique among games for mobile devices is the "real-time" nature of growing a virtual plant nursery in Plant Tycoon. Unless a player pauses the game, plants will continue to grow and thrive, or whither and perhaps become bug infested-depending on how often the player monitors and nurtures the plants in the nursery.
