    • Problem session: show that the following game always ends. Suppose n players are sitting at a round table. Precisely n-1 cards are divided amongst them at random. They start acting (playing?) in rounds until each player has at most one card. At each round each player who has more than one card hands one card to each of his/her neighbors.
