Mahjong

There are a total of 144 tiles on the board. They are split into the following groups:

Bamboo

Characters

Dots

Dragons

Winds

Flowers

Seasons

Each type of tile appears four times in the game, with the exception of seasons and flowers, which only appear once.

When playing Mahjong, people sometimes experiment with setting the tiles up in different forms. The default form is "Turtle", but you can cycle through a number of different forms to play. Once you make your first move in the game, you can no longer switch forms for the rest of the game.

The gameplay is quite simple, though solving the game can be surprisingly tricky. Gameplay consists of finding a pair of tiles that match each other and that are open to be removed from the board. A tile can be removed if:

It doesn't have a tile next to it on its left and/or right side.

It doesn't have another tile covering it.

A pair of tiles matches if they are in the same group and have the same type within that group. For example: Bamboo-5 can only match another Bamboo-5 tile. Bamboo-1 can not match Bamboo-2. However, the flower and season tiles are an exception to this rule. Any flower tile can match with another flower. Similarly, any season tile can match with another season tile.

If you get stuck, you can always ask for a hint. You can also undo your moves whenever you want.
