  • Mahjong is traditionally played fast. If you do not make a move in the allotted time, the move will be made for you automatically: it will be a simple pick and discard of the tile just picked.

  • If you lose Internet connection, you can reconnect by reopening the web browser or by selecting the game table's Menu button followed by Reconnect.

  • In our 3D and 2D Mahjong, you can zoom in on tiles discarded by opponents and on open discard by double-clicking on that area and the camera will move in to that area. An extra click returns you to original view.

  • Placing a cursor over a tile gives you information about that tile

  • If any player does not make a timely move, the game will make a default move for that player: pick a tile from the wall and discard that tile. So if a player had disconnected and then reconnected after a while, that player may discover that the game may have made several default moves.

    There are a couple of good reasons the game makes default moves at time expiration - (1) keeps the pace up - otherwise any potential player can stall everyone else and (2) historically, mahjong players must play fast!
