Shanghai

Template:Infobox Shanghai, originally developed and released for the NES, is based on Mahjong solitaire, which is a tile matching game. In Shanghai, the player removes both free tiles of a matching pair until all 144 tiles are gone. The challenge comes from devising a strategy to free up tiles so they can be removed from the stack. Shanghai only has one tile formation with which to play, although the color and picture scheme on the tiles can be selected from a list.

The object of the Mahjong solitaire board game is to match and remove alike tiles and get rid of the entire stack of five layers. To removing a tile it must be:

• Free: No other tile is lying above or is partially covering it and no other tile is lying to the left and to the right of it. In other words, one side must be free for the tile to be removed.
• Pairs: One must remove the tiles in pairs. Two tiles are identical if they look exactly the same such as "O". Other pairs include flower and season tiles. Any of these tiles can be matched up with another.

Tiles

Game screen.

A Mahjong set consists of 144 tiles. These are split in seven groups, called sets. There are nine ball tiles, nine bamboo tiles, nine characters tiles and four seasons tiles. Each season only appears once. There are also four wind tiles: East, South, West and North represented as their Chinese characters. The four flowers tiles also only appear once each: ORC (Orchid), PLM (Plum), BAM (Bamboo) and MUM (Chrysanthemum). Any flower can be paired up with another. Finally, there are the dragon tiles: Green Dragon, White Dragon and Red dragon. They are badly drawn in this game, but matching up two look-alike tiles is not as hard as knowing what it represents.

The Level at the bottom shows you the height of the tiles, as the game is only two-dimensional. It is recommended to learn this early, as often one forgets the inside tiles are actually higher and free to remove.

Strategy Tips

• When removing a pair, an identical pair exists in the layout. Check if the other pair has any problem being removed later or one of the tiles you want to remove now should rather be used with another of its kind.
• Long rows and tall stacks are hardest to remove and block the most tiles. Work on those first but still keep the other strategies in mind when doing so. Plan ahead to see which areas might have problems and which tiles need special attention, so you do not remove a pair and get stranded with one you cannot remove.
• If all of a kind can be removed, do so straight away to clear space. An emptier board is much easier on the eye and mind and after all, the objective is to remove all tiles anyway.
• Using the hints shows you one possibility, not the best one. Following this advice might lead into a dead end.
• If you have the choice between 3 tiles, keep the one that is least affecting the rest of tiles. In other words remove the one that frees up the most tiles.

Game Modes

Start screen.

• Solitaire: 1-Player. Remove all tiles without a time limit.
• Tournament: 1-Player. You get 1 point for each tile removed. Go through several puzzles with or without a time limit. Choose 5, 10 or 20 minutes to complete as many sets as you can.
• Challenge: 2-Player. In this mode you have time-limited turns. Choose between 10, 20, 30, 60 seconds per turn. Player 1 starts. Inevitably, some turns will result in a match being removed and some won't. At the end (when the layout is clear or unwinnable) the player with the biggest score wins.
