Playing Mahjong is easy - the basic rules are simple.
Remove pairs of matching tiles until there are none left.
You can only remove tiles that have at least one 'side' open so that you can pick it up from there.
Most tiles have to be matched with an identical tile
Some tiles are in a group and you can remove any two from that group as part of the pair.
These have blue numbers in the corner. You can select any two Flowers to match together.
These have brown numbers in the corner. You can select any two Season tiles to match together.
Sometimes you may run out of possible tile matches. You can 'shuffle' to continue playing, or abandon this deal and start a new layout.
