One Device, Two People Taking Turns
Put one phone, tablet, or computer between you and open the page. No room, no waiting for a connection. Finish your turn, then pass the device. If you are keeping score, agree on undo first, then play two games and swap Black.
Follow the Turn Marker
The status line says whose turn it is. Tap a tile in your hand. If it fits only one end, it plays at once; if both ends match, tap the left or right of the chain next. Tapping the other hand or a mismatched end does not count as a move, so wait until the turn is finished before passing the device.
Legal Is Not the Same as Good
The usual arguments are which end a double should take, whether to hold a high tile, and how many tiles are still in the boneyard. The board only accepts a match to an open end, but legal does not always mean best.
Two Games Make a Fair Set
Black always opens, so a two-game set is the fair unit: swap seats for the second game. The move list records every play, draw, and pass. If you need to see which tile closed both ends, replay the game.
