This game is also known as "Shisenshou Joshiryouhen".
'Sichuan' is the Chinese translation of 'Szechuan', which is the largest province in China. The game at hand here is indeed Szechuan-style solitaire mahjong, where the object is to match two identical unblocked tiles until the board is clear. This type of solitaire mahjong is also referred to as 'Shisenshou'. The tile layout presented herein is one of many traditional Chinese Szechuan-style solitaire arrangements.
