About Tycoon Games
Tycoon games are about watching small numbers become very large ones. You start with a simple shop or farm, earn a little money, and spend it on upgrades that earn even more. Idle games keep this going for you even when you are not clicking.
Early on, put your money into whatever earns income automatically, because that pays for everything that comes later. Compare the cost and the return before you buy. There are more games like these in clicker & idle games.
