To win the game, you have to keep you “Caffeine Level” up until the “Chronometer” is empty in the last of four levels. That means drinking enough coffee out of the cup on the right. Otherwise you get too tired and lose. When the cup is empty, use the coffee machine on the left to refill. When the coffee pot of the machine is empty, you need to brew new coffee, but you need money in order to do so. To earn money, you have to do work on the computer. But your caffeine level drops faster while working.
When you have enough money, you can upgrade the cup, machine and computer screen.
