Ryuutouden

Ryūtōden is a two player variant of Activision's Shanghai puzzle game also known as solitaire mahjong. The goal is to remove all 144 tiles by matching them into pairs, but only tiles which are visible and have a space to the left or right can be removed. The game features four different tile sets and player(s) can choose to display hints or reverse moves. A mode with a time limit (either 15, 10 or 6 minutes) is available as well.
