Enabling or disabling the Undo feature

To enable or disable the possibility to undo your last discard:

Choose Preferences on the File menu.
Choose Gameplay under the User Interface section in the category tree of the Preferences dialog box.
Check or clear the Undo box.

Note: When the feature is enabled, you can draw back the tile you have just discarded as long as the tile is visible in the discard slot by clicking the discarded tile, or by pressing the SPACEBAR (default for claiming a tile).

Tip: If you want to have extended undo capabilities, check the Replay box in the same option group. This lets you start over the current deal and move back and forth to another point in the game using the history list of the Game Manager.
