Mahjong scoring is centered around the wind tiles and the seasonal and
floral tiles. Playing these all togther gives the maximum score; i.e.,
4 N, 4E, 4S, 4W will give you 500 points. The seasonal and floral tiles
played together and back to back will give you 300 points but increases
later in the game.

The other tiles score higher as you match more in a row but never equal
to the hundreds like the color tiles. Dragons are also only fillers,
not many points no matter what.

Hope this helps.
