The hand can end in one of two ways:
First, someone declares Hu. If the dealer manages to Hu, he/she retains dealership. This is referred to as Diao Zheng. Otherwise, the dealership moves to the next player (in counter clockwise direction).
Upon Hu, the winner then counts the number of Doubles and announces it. The others then pay the winner the appropriate amount of points. If the winner has over-declared the number of Doubles he/she has, it is the duty of the other players to announce the correct number of Doubles the hand is worth. If no one notices, then they should give the winner the amount of points he/she has declared. If the winner under-declares the number of Doubles he/she has, it is polite of the other players not to say anything. Any person pointing out the irregularity will pay for all the others the difference between the declared and right number of Doubles.
If the hand of the people declaring Hu is found to be incomplete, a Zha Hu has occured. See the section on Faults & Penalties for details.
Second, the game ends in a draw. This happens when there are no more tiles left to draw in the drawing pile. The end of the drawing pile is reached when there are only 15 tiles left. The last tile that is drawn does not have to be discarded.
There are four variations to determine who will dealer for the next hand:
(i) so long as the current dealer has Kong/Um Kong, then he/she retains dealership,
(ii) so long as there is any Kong/Um Kong, then the dealership moves on,
(iii) dealership moves on in the event of a draw, or
(iv) current dealer retains dealership in the event of a draw.
Once the hand ends, the tiles are pushed to the centre, covered and “washed” in preparation for the next hand. It is impolite to look at other people’s cards (especially if the player does not expose them) or to grab at other people’s tiles at the end of the hand.
