For everyone who doesn't know what mahjong is, it's basically Chinese solitaire played with tiles ("dominoes") instead of cards. Every "new" mahjong game follows the same basic rules usually with just new designs on the tiles and different rewards (in this case, hentai).
well for your information, mahjong is indeed a Chinese table game, originally. However, the japanese have created their variant of mahjong. The rules and the scoring work differently in both variants of mahjong. However, they share the same fundamental principle, which requires 14 tiles made of four sets of sequences, triplets or quads (12 tiles) and a set of pair (2 tiles) to make a "legal" mahjong hand. They also share few similar mahjong hands, which means that these hands can be used in both variants. They also share a lot of terms, albeit different pronounciations. Well, ive barely played chinese mahjong. so, i cant tell you in details on how the scoring works in chinese mahjong. But, ive been playing japanese a.k.a riichi mahjong for a long time, be it offline or online. So, i know how to play japanese mahjong and im an avid fan of the game.
Oh, thank you for explaining to me. It is similar like Chinese take Japanese kanji [漢字] for their language and then japanese will move to Hiragana and katakana for their main language and also they use some Kanji if it necessary. By the way, it will take me week or months to know basic of this mahjong games xD . So i would pass~
Also i interest with anime, not mahjong unfortunately
