Mahjong Soul has pushed higher on Steam during its Sword Art Online crossover week. The Chinese Steam version of the free-to-play Riichi mahjong game climbed from No. 99 to No. 57 on Steam's latest most-played chart, giving it one of the sharper lower-table moves in a week led by bigger names and newer PC releases.
Steam's weekly chart lists Mahjong Soul with a 21,499-player peak, up 42 chart places from the previous week. By late Sunday UTC, Steam still showed 2,260 players in-game on that listing, keeping the crossover-backed run inside the top 60 rather than on the edge of the chart.
Sword Art Online gives players a new event to chase
Yostar Games launched the Mahjong Soul x Sword Art Online event after maintenance on April 21, with the collaboration scheduled to run until May 12 at 1:59 p.m. UTC-7. The event is called Oath of the Sword and brings Kirito, Asuna, Leafa and Sinon into the anime-style mahjong game as limited collaboration characters.
The event is not only a character banner. It also adds Azure Expanse animated outfits, Sword Art Online themed table decorations and a limited mode called Vulture's Deal. In that mode, a Spoils phase lets the hand winner swap starting tiles with other players before the next hand begins, changing the usual flow of a match.
Players can also collect Cream-Topped Bread through Ranked matches or Vulture's Deal to earn event rewards, including an exclusive collaboration tile back. The crossover story has Kirito, Asuna, Leafa and Sinon arriving in One Han City and meeting Ichihime and the rest of the Mahjong Soul cast at the table.
A crossover bump in Steam's lower top 100
Mahjong Soul's Steam movement is tied to a current, playable event with recognizable characters and a temporary rules twist. Sword Art Online is still a large anime and games brand, and the event gives returning players more than cosmetic login rewards to check.
It also gives Steam's lower top 100 another live-service story after the latest weekly chart was led by bigger jumps from BidKing and Vampire Crawlers. Mahjong Soul is not competing with Counter-Strike 2, Dota 2 or PUBG at the top of Steam, but a 42-place rise is a meaningful move for a regional Steam listing built around a niche multiplayer mahjong audience.
The Steam version behind this movement supports Simplified and Traditional Chinese and connects to Mahjong Soul's international Chinese services, according to its store listing. That makes the chart move more specific than the broader global Mahjong Soul audience on mobile, browser and other PC versions, but the crossover itself is also being promoted through Yostar's wider Mahjong Soul channels.
