List of special rooms in Mahjong Soul

Special Rooms are offered in Mahjong Soul. They provide players with alternative rooms either with a different ruleset, or used for specific purpose. Most of them are temporarily available during events.

Melee Room

Melee Room is a special room with a predefined subset of local yakus. In Melee Room, players can score a hand with those local yaku, where some of them are not valid under regular riichi mahjong.

Casual Room

Casual Room provides a casual gameplay, without requiring creating a friendly room and find sufficient players manually. The ruleset is identical to normal gameplay, while both ranking and copper-coin requirements are not applied, as well as no bonding value or chest for reward.

Casual Room is long-term available.

DoraDorara

DoraDorara is a special room with 3 dora indicators revealed in advance. That being said, there're always at least three doras in each round, making it much easier to score a larger hand. The amount of kan as well as four-kan abortion still share the same restriction to the regular game, though only first two kans can reveal kandora indicator, while the last two cannot. The maximum amount of dora still remains 5 (or 10 with ura) in total.
