Mahj Dragon is four-player mahjong for iPhone and iPad: nine games, computer opponents for each, and games with friends in the same room. There are no accounts and no servers, so most questions are answered below. If yours isn't, write to support@okbyus.com.

What you need

An iPhone or iPad on iOS or iPadOS 17 or later.
To play with friends: each player on their own iPhone or iPad with Mahj Dragon, all on the same version, in the same room, with Wi-Fi switched on. You don't join a network and you don't need the internet; the devices talk straight to each other.

Starting a game against the computer

On the home screen, tap PLAY, then PLAY vs AI.
Choose a place on the Atlas. Each place is one of the nine games, played at its own table.
Tap PLAY NOW and choose how long a game: one round (about half an hour) or a full game of four rounds (about two hours).

The three other seats are computer opponents. If you leave in the middle of a hand, the home screen offers to resume it where you left off.

Never played? The first time you open the app, the Dragon offers a teaching hand: one scripted game, with every idea shown once. You'll also find it under LEARN as Your First Game, beside Your First American Hand.

Playing with friends nearby

One person hosts. They tap HOST, choose a place on the Atlas, tap PLAY NOW and choose how long a game. (Open a Table in the PLAY LOCAL lobby does the same.)
Everyone else taps PLAY, then PLAY LOCAL. The host's table appears under Tables open nearby; tap Sit down. A host can also bring you in from their side, and you'll be asked whether to join.
Fewer than four of you? The host can deal the empty seats to Dragon Bots. When four seats are filled, the host taps Start the game.

If a player's device drops out during a game, a bot takes over their seat and keeps it for them until they come back. Your table name is what others see: it's your Game Center name or your device's name until you change it in Settings. Settings › Nearby invitations decides whether a host may seat you: ask first, instantly, or never.

The three levels of opponent

Every game has three levels: Level 1, Level 2 and Level 3. All three are trained by us. Start gently, then turn them up.

Choose the level in Settings › Bot strength. Switch on Choose each bot to give the player on your right, across and on your left each their own level. If an opponent does something that looks wrong to you, leave a comment from the table and tell us what happened.

The rules card and HELP

TABLE RULES, at every table, shows that game's rules card: what a winning hand is, what you may claim, and how the hand is scored.
HELP asks the Dragon. She reads your rack and suggests what to throw, or what to pass in the Charleston, and tells you why. In Settings you can make her advise automatically every turn, or switch her off.
In American games, the whole Dragon House Card is in the Learning Center under LEARN.
Each game plays one written version of its rules. A few table traditions can be set in Settings › House rules, such as the American Charleston's optional passes and some scoring limits.

Nearby players can't see each other

Allow Local Network. iOS asks the first time you open PLAY LOCAL or HOST. If it was turned down, go to Settings › Mahj Dragon on the iPhone or iPad and switch Local Network on. Without it, Mahj Dragon can't see anyone nearby.
Switch on Wi-Fi on every device, in Control Center or Settings. The lobby says so when it is off. You don't need to join a network.
Update everyone to the same version. If a nearby player has a different version, the lobby says so; update both devices from the App Store.
Keep Mahj Dragon open and on screen on every device while you gather, and stay in the same room.
Check Nearby invitations. If it is set to Never, hosts can't invite you, though you can still sit down at their table yourself.
Still nothing? Close Mahj Dragon on every device and open it again.

The app closed unexpectedly

Mahj Dragon keeps a short note of what it was doing. Next time you open Settings, it offers to send that note. You'll see every word of it first, and it goes from your own mail app. It's the most useful thing you can send us about a crash.

Leaving a comment

Every rules card, the end of every hand, the Learning Center and Settings have a way to leave a comment: a rule that seems wrong, an opponent that played oddly, or a suggestion. You see the whole message before it goes, and it goes from your own mail app to comments@okbyus.com.
