Calling a Discarded Tile
- Single tile — ONLY for a Mahjong
- Pair of tiles — ONLY for a Mahjong
- Run of tiles (e.g., 2-4-5-6) — ONLY for a Mahjong
- Group of dissimilar tiles (e.g., N-E-W-S or 2-0-2-6) — ONLY for a Mahjong
- A player can call for a tile when it completes your grouping of three or more tiles.
- Once you pick up a tile and expose, you can not add or remove tiles from the exposure.
- A player cannot pick up a discarded tile on a concealed (C) hand, except to declare Mahjong.
- A player cannot pick up a discarded tile for a single or pair, except to declare Mahjong.
- A player cannot pick up a discarded Joker; that Joker is dead.
OMG Mahj tip: When calling, announce clearly (e.g., “Call!”), take the discard, build your exposure, then place it to the right of your rack.
