The cabbage, the goat and the wolf must go from one side of the river to the other side without eating each other. We have a boat on which only one item can be loaded (wolf, goat, cabbage). Obviously, we cannot leave the goat alone with the wolf, or the goat alone with the cabbage. Programming mode: Click on the buttons to program the crossing of each one of the three items. Manual mode: Click on the items to have them loaded on the boat or unloaded, on the boat to make it cross the river.
