In this simple resource management game, you have three trucks to load with packets of four possible different colours. The order of the packets is random and you have to load them in the order in which they arrive. Each truck holds six packets and will only leave when full. The greater variety of colours you fill them with, the longer it takes before they return, so you must decide how to mix the colours between trucks. All the time, new packets are arriving at an increasingly faster rate, and the game ends when there are too many in the queue.
