Mahjong Rules

Mahjong (sometimes spelled Mahjongg) in its original form was created in China during the late 1800's, but has through the years gained world-wide popularity. Our version is the solitaire variant of Mahjong, which is a more recent invention. The object of the game is to match and remove pairs of tiles until there are none left on the board.


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.


The game is won when you have removed all the tiles.

Every game has at least one path to victory, but it is possible to get to a point where you have no possible moves before finishing the game. In that case, you can always undo your moves to a point where you believe you can make the game winnable.

About Mahjong

Mahjong is a game we've wanted to make for years, but finally got around to making now! The main thing stopping us was that we didn't have good graphics for it. Usually we've used free graphics from openclipart.org for our games, but this time we used fiverr.com and got custom graphics made. We're really happy with the results! This is also only our second game to have any sounds! We bought our sounds from soundsnap.com, a great site for sound effects. But don't worry, you can of course turn off the sounds in Options!

Mahjong was mainly developed by Kjartan, one of our first full-time employees. Other games Kjartan has worked on are Backgammon and Kings in the corners. As always, any comments, questions, ideas for other games or anything else can be sent to admin@cardgames.io.
