Understand every move.
Practice from a true top-down table with four walls, four players, a visible draw source, and coaching that explains what changed—not simply what a bot chose.
Guided American Mah Jongg
Play from the first roll through Mah Jongg or a wall game.
Everyone plays the card you select. Follow the coaching, or hide it and practice making your own decisions.

Players
Choose how each opponent plays
Beginner bots make legal but inconsistent choices. Intermediate bots protect the strongest current card match. Expert bots compare card equity, useful unseen copies, Joker dependence, backup lines, public danger, and wall timing.

Rule set
Agree before the tiles move
The core game follows standard American Mah Jongg structure. Optional procedures and house rules are identified separately so the coach can explain which rule caused an outcome.
Core tableAmerican Mah Jongg
- 152 tiles: 8 Flowers, 8 Jokers, and four of every other tile
- East starts with 14 tiles; every other player starts with 13
- Jokers cannot be passed, claimed from the discard field, or used for a single or pair
- On a turn, a matching natural tile may be exchanged for a Joker in any live exposure
- Mah Jongg takes priority over an exposure call; equal calls follow turn order from the discarder
- A Jokerless win pays double, except a Singles & Pairs hand

Training & home optionsChoose what the interface reveals
What the trainer handles automatically: digital discards are always named correctly; illegal tile counts, Joker passes, incompatible exposures, late calls, and false Mah Jonggs are blocked for every complete learning or saved card profile.

Choose East · house convention
Everyone rolls one die
For this practice table, the highest roll becomes East. Tied players roll again. This is a common home-table method; the League’s published selection procedure uses two dice.

Suit 1 Suit 2 Suit 3D Dragon Exact tile in rack Joker-supported slot
Choose up to three lines to track. Pale green tile positions are exact tiles in your rack; gold positions can be covered by a Joker. Tracking is only a bookmark.
No lines match your current exposures.
Show all lines to review the conflicts. Hiding lines does not change your tracked hands or the game.
Your official card stays beside you.
This mode never displays or reproduces official hand text. Give your three possibilities private labels so you can keep your place while playing.
How the bots use this mode: they follow standard Charleston, Joker, call, exposure, draw, and discard rules. Hand-specific strategy and automatic progress require a private, licensed card adapter; until one is connected, the coach labels those judgments as unavailable.
