The shipyard is a very busy place, and everyone is in a big hurry. How many crates can you stack before quitting time? Using the hand crane, place the crates in a single stack, one on top of the other. If a crate falls off the stack, your turn is over. Meanwhile, the other players are trying to stop you. If they roll a six on the die, it's quitting time and your turn is over. - BoardGameGeek
