Shisen-Sho (Shisen-Sho Mahjongg-like Tile Game) is a solitaire game developed by KDE as part of its kdegames package. The game runs similarly to Mahjongg. However, in Shishen-Sho, the Mahjongg tiles are arranged in one layer only. The game is played by connecting matching tiles by means of a line. Lines can be horizontal or vertical. However, if the matching tiles cannot be connected by one single straight line, the tiles may still be matched if the line connecting them has no more than two bends to it. It means that the line can go around corners however only up to 2 bends. Also, the line may not pass through other tiles that are yet to be removed from the board. The player wins when all the tiles are removed from the board. However, if there are no more possible moves but there are still remaining tiles, the game ends and the score of the player is tallied according to the number of matches he makes. Some game boards are unsolvable. To avoid these, users can tag on Create Solvable Games Only option.
Shisen-Sho (Shisen-Sho Mahjongg-like Tile Game) features different Mahjongg tiles styles. There are dots, bamboos, characters, winds, dragons, flowers, and seasons. Flowers and seasons do not have exact match pairs. However, they can be matched with any other tile from the Flowers or Seasons group.
