If there are no playable dominoes left, your turn is skipped. Scoring Make end tiles add up to a multiple of 5 to score that number of points. The hand ends when either player uses all of their tiles.
The box is six dominoes long. So you can have all six dominoes lined up in a row. There’s only one way of doing this. Or you can turn two of them round. There are five different ways of doing this.
