What you should know
If you play with tiles or cards, remove blocks of the same type that are not covered by other blocks or touching them on all sides.
When there are no more pairs to remove, shuffle the remaining blocks and stack them again.
Or play online. Simply select the tile arrangement and remove the corresponding blocks.
A typical game of mahjong uses dice with Chinese symbols. However, you can play by the same rules using a Western deck of playing cards. Mahjong tiles can be purchased online or from a game store. While cards may be a reasonable substitute, using real solitaire games will prove more enjoyable in the long run.
