You start with five levels of tiles which are stacked so some are
covered up by the tiles on top.  The harder the level you set in the
Preferences dialog,
the more tiles are covered when the game starts.  The object of
GNOME Mahjongg is to remove all the tiles
from the game.  To remove tiles you have to find matching pairs which
look alike.  A matching tile will usually have the same number of buttons
or markings on it or will look similar to each other.
As an example, the highlighted tile, in the
figure below, has six buttons.  The matching tile is the one which
also has six buttons.  The tile is on the right-hand end of the third row from the bottom and there is another near the top of the fourth row from the bottom.
If you want to match the tile on the top level, you need to look for the
tile with the same green bamboo symbols.  Do you see a matching tile yet?
There are three tiles, which are visible, that match the tile on the top
level.  Two are to the left and the lower right. The thrid one is on the top row, but you can't
remove that tile yet because the tile isn't
on the outside of the stack of tiles.  Later I'll explain more fully which
tiles can be removed and which tiles can't be removed even though they match.
I'll let you find the other two matching tiles, which are visible, on your own.
Main window.Mahongg is played by
clicking on two matching tiles that are then removed. Play
continues until all the tiles are removed or there are no
available pairs.
Only tiles at the far left and right edges on each level
can be selected.  This is because you can't remove any tiles which
aren't at the far left and far right sides.  If the tiles are on
a different level and at the left or right sides, those can be removed
when you find another matching tile.
If you can't match any more tiles, a
dialog will appear telling you no more tiles can be matched and giving you the option of shuffling the tiles or undoing your last move (although you may have to undo many more moves to find your mistake).
