Mahjong 4 Phone Shared Game

Tile image paths use images/tiles/1bam.png, images/tiles/1dot.png, and images/tiles/1char.png through 9 only. Voice files use sounds/discard/1bam.mp3 for discard tile calls, sounds/pung/pung.mp3 for Pung, and sounds/chow/chow.mp3 for Chow first. Browser speech is used only when the mp3 file is missing.

Joker rules: Joker may fill missing tiles only inside the concealed hand/winning-hand check. Joker may complete Eskalera only by filling the exact missing number in the exact same-suit 1-9 sequence. Joker may also fill missing tiles for 7 Pairs and Joker Eye. Joker is never allowed inside exposed Pung, Chow, or Kang meld claims.

Win check rule: Every declared win is verified before point adjustment. The winning hand is revealed to all players. If the declared hand is not complete or the tiles/sets are wrong, the win is rejected. False Win Now from a discard makes the declaring player give 6 points to the discarder and 3 to each other player. False Win Now from a draw makes the declaring player give 9 points to each other player.
