The player sees a road network, on which trucks transporting food containing gluten are travelling. A symbol on top of the trucks indicates that the vehicle is carrying gluten. The player’s task is to prevent the trucks from reaching the factory by clicking on the trucks approaching the factory. By clicking on a truck, the player can make the gluten symbol disappear, as a result, the truck is considered safe and can pass the factory. The game consists of three levels which gradually increase in difficulty. This means that the number of trucks the player must manage increases. The player wins if none of the trucks reach the factory on the three levels.
