How does seating and wind assignment work at the start of a game?

At the start of a game, seats are typically assigned randomly by rolling dice or drawing tiles. Each seat corresponds to a wind: East, South, West, and North, which determines each player's seat wind tile bonus for that round. East seat is the dealer for the first hand. After each hand, seats and wind assignments rotate, though the exact rotation method varies by ruleset. The game typically consists of at least one full East round and one South round.
