Mahjong Vanilla Syndrome — About this game
A mysterious house leads to an unexpected journey when its visitor falls through a portal. On the other side, the bunny-eared guardian Vanilla explains that returning home requires victories over the realm’s mahjong players. Character conversations provide the framework for a succession of tile matches. Each hand asks you to balance efficient construction with attention to the opponent’s progress: calling quickly can be useful, but it can also leave fewer legal ways to finish. The fantasy setting changes who you meet and why you play, rather than replacing the tile rules with action combat. Read the available table commands carefully, watch for valid winning opportunities and use the score screens to follow the overall contest.
