Honor tile

Honor tiles are the suitless tiles in a mahjong set: the four winds (East, South, West, North) and the three dragons (White, Green, Red). Unlike the number tiles in the three suits, honors have no numeric value and therefore cannot form chows, since a chow requires a consecutive sequence. They can only be used as pairs, pungs, or kongs, which makes them blunt but often valuable instruments in a hand.

Honor tiles sit at the heart of many scoring rules. In every major variant a triplet of dragons, of the round wind, or of your seat wind is a 'yakuhai' or value triplet that scores directly, while ordinary number triplets do not. The seat wind rotates with the players and the round wind changes as the game progresses through East and South rounds, so the same wind tile can be worth points to one player and worthless to another at the same table. Honors also define prestige hands like all honors (tsuuiisou), little and big three dragons, and the four winds hands.

Because honors cannot extend into sequences, a lone honor early in the game is often discarded, but they are also relatively safe to hold defensively since an opponent can only use them in a triplet or pair. In riichi, honors that are guests' winds (neither seat nor round) are particularly safe late-game discards.

For example, in an East round a player seated South who collects West-West-West gains nothing for it, because West is neither the round wind nor their seat wind. The same player drawing Red-Red-Red would score a yakuhai, since dragon triplets always count regardless of seat or round.
