The toolbar can be moved around the
desktop.  If you click on the far
left side of it, you will be able to drag it any place
on the desktop you wish.  The
toolbar also snaps into place
at the top and left side of the Main Window
in GNOME Mahjongg,
but the default place the toolbar is located, and the best
in my opinion, is under the menubar.
The toolbar contains the following buttons:
New
This button starts a new game with the current settings.
Restart
This button restarts the current game to the beginning without
shuffling the tiles.
Pause
This button pauses the game.  When the game is paused, the clock,
at the bottom right corner of the Main Window,
stops and you cannot see any of the tile's faces.
Undo
This button replaces two tiles you removed until
you reach the beginning of the game.
Redo
This button replays your previous move, the Undo
button took back.
Hint
This button gives you a pair of matching tiles to remove.
There status bar at the bottom of the window gives you
information on the current state of the game:
Tiles Left:
This shows the number
of tiles remaining to be matched.
Moves Left:
This number
of possible matches you can make.
