Shisen-Sho Mahjong 1.0

Shisen-Sho, also known as 'Shisen,' 'Four Rivers,' or simply 'Rivers,' is a tile-based game rooted in Japanese tradition that utilizes Mahjong tiles. It bears resemblance to Mahjong solitaire but offers its own distinctive gameplay nuances. The primary objective is to match pairs of identical tiles and remove them from the playing field, with the goal of clearing all tiles.

The game has been adapted into numerous computer-based versions, allowing for varied implementations and user experiences.

Rules:

• The main goal is to eliminate all tiles from the board.
• Only two matching tiles can be removed at a time.
• Two tiles are eligible for removal if they can be connected by a path comprising no more than three straight lines—horizontal or vertical—passing solely through empty spaces on the board.
• The game concludes either when no further moves are possible, leaving tiles on the board, or when all tiles have been successfully removed.
