Rummikub

For a player's first move, they must play a set (or sets in some versions) with a value of at least 30 points. Point values are taken from the face value of each tile played, with the joker (if played) assuming the value of the tile it is being used in place of. A player may not use other players' tiles to make the ``initial meld''. If a player cannot make an initial meld, they must pick up a single tile from the pool and add it to their rack. Play then proceeds to the next player.
