Calls & Declarations
Ron
Also called: 放炮, deal in, discard win
Winning by claiming another player's discard — they 'dealt in' to you.
Ron is the call you make when another player discards your winning tile. The discarder pays the entire win amount in most variants. In Riichi, you must declare ron; in HK and other variants, you simply call 'pon!' for the win. Ron-wins typically score slightly less than tsumo (self-draws) because part of the hand was completed by an opponent's tile.
