A night, start to finish
How a club night runs
- Name the night, pick the tables. Plan one table of four or up to thirty-two. Choose artwork for the invitation and add your house note.
- Send one link. Guests open a card, not a form. They answer by name, say if they can bring a set, add a friend's name, and leave you a note.
- A yes takes a seat. When the room is full the line forms on its own, and the next seat goes to the next name. You can add anyone by hand.
- Seat the room. JONGG assigns players to tables of four, shows the next seating after each hand or on a timer, keeps standings, and makes thank-you cards to share afterward.
Your club
A club gathers your people and their weekly tables under one name: a library group, a Tuesday crowd, a class.
- One invite link to join; you keep the roster.
- Weekly tables: the same people, the same time each week and shared table settings.
- A tally of points for the year. Just bragging rights, no betting.
- Playing with real tiles? Score the game in the app and the tally stays with your table.
Be found
Some groups want to stay closed; some want a fourth. Listing is opt-in, by town, and never an address.
- List your club, and say whether newcomers are welcome.
- Post an open seat for one night.
- Approved instructors can add teaching details and a booking link.
Open seats and contact details depend on what each organizer has shared.
Teach with it
A guided hand with patient bots for the beginner who is afraid of slowing the table down, and paper for the room.
- The practice packet for a class.
- Short lessons and a daily puzzle to send home.
- The Charleston guide, a scorekeeper and a hand checker beside the rack.
Beautiful enough to share
Every invitation is a card in your chosen colors, with digital tile artwork, ready for you to send to a group chat or a story.
- Two invitation styles today, Garden Party and Lilac Hour.
- An invitation image in story, post, square or link sizes, generated on your device — nothing uploads anywhere.
- A thank-you card for each guest after the night.
Twenty-four players: six tables, six complete sets
For 24 American mahjong players, prepare six tables of four and six complete sets, with racks and dice. Agree on the printed card edition and tell each player what to bring. A promise to bring a set is an equipment offer, not proof that a complete set is ready at the venue.
In the planner, open Add a table or a note and choose 24 seats. If you play, keep I’m playing selected: your place counts among the 24. If you only host, turn it off. Save the invitation before sharing its link.
Check equipment on the host’s phone
A guest can mark I can bring a set before sending Going. As host, open Guest list to see equipment offers beside the names. Contact six suppliers and confirm a complete set from each, then assign a set to each physical table in your own checklist.
If a supplier changes to Can’t, check the list again: their set offer no longer counts. A replacement player can fill the seat without bringing equipment. Secure a replacement set before treating the room as ready.
Check the seat, not just the yes
When all 24 places are taken, another Going reply joins the line. If a place opens, the guest should reopen the invitation and read their current seat status. A waitlist position, an offer that still needs accepting and a confirmed seat are different states; follow the action and any deadline shown.
Ask guests to return in the browser they used to answer. Keep a private home address out of public notes, forwarded invitation images and equipment checklists you share widely.
What organizers ask
Do guests and club coordinators need accounts?
Starting or joining a club, or hosting a game night, takes a free account. Guests can answer a personal invitation by name in their browser without an account or app download. Club coordinators also sign in with a verified account for shared organizer tools. Joining a club does not reserve a playing seat; answer each invitation separately.
How big can a night be?
One table or thirty-two — four seats each. The list, the line and the headcount work the same at every size.
What does it cost?
Play, learn and host free forever. Membership adds stronger practice and drills, decision review of the hands you play, and your full stats. Guests never pay and never need an account, and an invitation never carries an advertisement.
We play with real tiles. Is this for us?
Yes. Plan an in-person night with your own tiles and printed card. Use JONGG for invitations, seating and your weekly table, with the scorekeeper, Charleston guide and checker beside the rack.
Do we need the app?
Open these tools in your browser without an app download. Try them on the device you will host from. We have not verified every device or browser version. The iPhone and iPad app is in private testing.
