Kongvene — your table, organized. Running a mahjong group means more than showing up to play. There's the group text to find out who's in, whose turn it is to host, who's bringing a set, who still owes for last time, and scrambling for a fourth when someone drops. Kongvene handles all of it, so you can focus on your hand. RSVP BY LINK — NO APP NEEDED Share one link in the group text. Friends tap it, add a first name, and pick I'm in, Maybe, or I'm out from any phone or computer. Their seat lands at the table like everyone else's. SEE WHO'S IN, LIVE Play days fill tables of four automatically, up to 4 tables (16 players), with a subs list that moves up when someone drops. Set a start time, and add the game to your calendar in one tap. TABLE MODE — A HELPER AT THE TABLE On game night, open Table Mode on one phone per table. Roll for East, roll to break the wall, and let the Charleston helper walk everyone through each pass, one step at a time. When someone calls Mahjong, name the winner and cue the Kongfetti. No scorekeeping, just bragging rights. It works with the Wi-Fi off. NEED A FOURTH One tap asks the whole circle. The first to say "I'm in" takes the seat. HOSTING AND THE SET Pick a host for each play day (the rotation suggests who's next), and see whether every table has a set. DUES WITHOUT THE AWKWARD FOLLOW-UP See who's paid and who hasn't, with a friendly reminder and a one-tap hand-off to Venmo or Cash App. Kongvene keeps the record; it never moves money. Each member only sees their own dues. RUN IT TOGETHER Organizers get their own Organize tab: upcoming RSVPs at a glance, who joined and when, and their tools in one place. Fix how a player's name shows in your circle, and share the work with co-organizers. Notifications (opt-in) tell you when a play day is scheduled, moved, or cancelled, and when someone signs up or drops. PRIVATE AND FREE Free for every member. No ads, and we never sell your data. Invite your circle with a simple code. Whether it's a weekly game with old friends or a club that's still finding its rhythm, Kongvene keeps your table running — so the only thing you have to think about is your hand.
