# Blitz Jong (疾风雀) > Real-time riichi mahjong with no turn order. All four players draw and discard at the same > time; each discard opens a claim window of a few seconds in which the whole table may > declare; and whether a player can act is governed by stamina rather than by whose turn it > is. The hand building, yaku and defence of standard riichi still decide who wins — only the > tempo is new. Free to play in a browser at https://www.blitzjong.com/ and on Steam.

Contact: support@blitzjong.com ## Facts - Genre: real-time four-player online riichi mahjong - Price: free to play; only cosmetics are sold (tile faces, tile backs, riichi sticks, table felt, music). Nothing that affects how a match reads is sold. - Platforms: browser (www.blitzjong.com), Steam (app 5183080), Android. Same servers, one account, one rank. - Steam release: 22 September 2026. The browser version is playable now. - Languages: English, Simplified Chinese (简体中文), Japanese (日本語) — interface and call voices. - A hand runs about 90–150 seconds. The default match is East-only, four hands; rooms can be set to a half-game. - Several players can win the same hand: a winner scores and steps out while the rest play on until the walls run dry. - Each player draws from their own quarter of the wall, so the fastest player cannot out-draw the table. - Ranked play across five tiers, with demotion protection in the lower ones. Every match is saved as a replay, reviewable second by second from any of the four seats. - Rules: identical to standard riichi (yaku, fu and han, furiten, kuitan, riichi with ippatsu and ura dora). The differences are that there are no turns, and rules once measured in "one go-around" (furiten, ippatsu) are measured in seconds. - Category: Japanese mahjong (riichi mahjong) — four players, 136 tiles, yaku and dora. Not Chinese Official (MCR) or a regional variant such as Sichuan or Cantonese mahjong. - Also described as: online mahjong, browser mahjong, free multiplayer mahjong, 4-player mahjong, real-time mahjong, 立直麻将 / 日本麻将 / 在线麻将, リーチ麻雀 / オンライン麻雀. - Relation to other riichi mahjong games (e.g. Mahjong Soul, Tenhou): same rules and scoring, so tile theory carries over; those are turn-based, Blitz Jong has no turns — all four players act at once, each discard opens a claim window of a few seconds, and stamina decides who can act.
