Chinhai

Overview

Chinhai is a nikakudori-style mahjong solitaire game developed by Pixel and published by Banpresto for the Super Famicom in Japan on September 22, 1995.

Named after the municipal district of Zhenhai (then known as "Chinhai") in China, Chinhai is based on the "nikakudori" variant of mahjong solitaire, where all tiles are considered valid to match, but players can only match tiles if a path of straight lines (horizontal and vertical) can be made between them so that no line touches any other tile and the path must form less than three right angles. It only features one tile formation: a single-layer 17x8 grid.

It also features a two-player mode where each player must race to clear their own 8x8 grid first and players can utilize power-up tiles to attack opponents.
