Then, you click the little tear-shaped icons that eventually will pop up. 3rd once you clicked enough of them, look to your top left, there should be a variable that shows how much DNA you have. Now, you can buy upgrades, look to your top right and there should be a button that says: "Disease", now click it. After that, you now see how much each item costs, buying these will increase your infection rate. In order to win you must have infected all the population, and killed 6,000,000 of the infected.
