The goal is to clear the board by removing the tiles. You must remove the
tiles in pairs. For a tile to be selected it must not have a tile on top, and
it must have a space open on the right or to the left of it.
The four season tiles will match even though they are not identical. The
four flower tiles also match even though they are not identical.
For each matching pair you get 50 points plus a time bonus. The faster you
match a pair, the bigger the bonus. The time bonus can be a maximum of 60. You
get 5000 points for clearing the board.
