== Dealer rotation ==
== Rule overview ==
Dealers have the following properties:
 
* The dealer is always the East seat. This means the dealer always gets the first draw, which is a slight increase to hand speed.
* A dealer's winning hands are worth +50% more (or about +50%, due to rounding).
* Dealers can [[renchan]]. When a dealer wins the hand, or when [[tenpai]] at [[exhaustive draw]], the wind seating does not rotate. This extends the game by an extra hand.
* Dealers pay x2 as much when another player wins via [[tsumo]]. (They do not pay more when [[ron|dealing in]].)
 
The current dealer is denoted by using the dealer marker. Alternatively, the dealer marker notes the original dealer, and some other method is used to mark the current dealer.
 
=== Dealer rotation ===
During the course of the game, the dealer seat rotates among the four players. Seats rotate when:
During the course of the game, the dealer seat rotates among the four players. Seats rotate when:
# A player other than the dealer wins a hand.
# A player other than the dealer wins a hand.
# The dealer fails to attain [[tenpai]] at [[ryuukyoku]] (exhaustive draw).
# The dealer fails to attain [[tenpai]] at [[exhaustive draw]].


Once every player gets to be a dealer once, the round wind changes. In a [[hanchan]], everyone gets 2 chances at the dealer seat.
Conversely, if a dealer wins, or is in tenpai at exhaustive draw, then the seats do not rotate. Each time this happens, the game length is extended by 1 extra hand.

Once every player gets to be a dealer once, the [[ba|round wind]] changes. In a [[hanchan]], everyone gets 2 chances at the dealer seat.


== Useful Info ==
Some rulesets only enable renchan if the dealer wins, meaning that seats rotate when the dealer is tenpai at exhaustive draw.
When a player is the dealer, the following properties apply:


* The dealer draws first, which is a slight advantage to hand speed.
==Strategy==
* The dealer's hand value is worth 50% more (or about 50% more) than non-dealer's.
Being the dealer is mostly beneficial. It is better to win as the dealer than not, due to the +50% score bonus and the ability to renchan (an extra hand, while retaining dealership).  
* If the dealer wins the hand, or is tenpai at exhaustive draw, the wind seating does not rotate, thus extending the game by an extra hand ([[renchan]]).
* The dealer pays x2 as much when another player wins via [[tsumo]]. (Dealers do not pay more when [[ron|dealing in]].)
 
Due to the +50% point modifier, players greatly benefit from being the dealer. Games are often decided by dealer turns. A lucky player may rise from 4th all the way to 1st through consecutive renchans.


However, being the dealer is not always helpful:
However, being the dealer is not always helpful:
* When a dealer has a large lead near the end of the game, they should avoid winning to avoid extending the game. After all, each renchan gives the other players a chance to build a [[yakuman]] and comeback.

* When another player wins by [[tsumo]], the dealer has to pay more. The extra points lost from tsumo can be significant during close games or with big hands.
