About this game
JANJARA puts four players around one automatic mahjong table. It is a simulator of the table itself—not a rules-processing client or digital referee.
Let the machine handle the automatic-table ritual: the lift, wall rise, wash, and preparation for the next hand. Once the tiles are ready, the table gets out of the players’ way.
Pick up and place tiles, organize your hand, move point sticks and chips, and clear the table for what comes next.
The focus is the physical experience of operating a shared table—not selecting actions from a rules interface.
Your group chooses the rules, judges the hands, and settles the results.
JANJARA does not determine legal actions, calculate scores, judge yaku, or correct the players. It operates the table and leaves the mahjong to the four people sitting around it.
Meet online, take a seat, and operate the same physical table together. Every player handles the objects in the shared space directly, bringing the freedom and responsibility of a real table into an online session.
JANJARA is for people who want the mechanical ritual of an automatic mahjong table and the freedom to play by their own rules.
Pull up a seat. The table is ready.
