A tile can be selected when there is no tile to its left or to its
right, and no tile is placed above it.
Such a tile is said to be "free".
In the following example, only the left and right tiles are free.
The tiles in the middle are not, because there are tiles to their left
and to their right.
In the following example, only the tile on the top is free. The tiles
below it are not, because there is a tile placed above them.
There are 42 different tiles. Three suits consisting of nine tiles each:
The circle suit:
The bamboo suit:
The character suit:
Two sets of honour tiles: the winds (four tiles) and the dragons (three):
Each tile appears four times, with the exception of the eight tiles shown
below which are unique:
The player must match two identical tiles to make them disappear.
The exceptions are the unique tiles. Although they are not
identical, a flower tile can be matched with another flower tile,
and a season tile can be matched with another season tile. It is
important to memorise these tiles!
The cursor is controlled using the joystick or the cursor keys
on the keyboard. A tile is selected by pressing Fire. If the tile
is not free, nothing will happen.
It is possible that the player will no longer be able to match
any tiles. In this situation, the player will be unable to continue
and the game is lost.
