Basic rules to the game are essentially the same. Game mechanics regarding turn order, [[Naki|tile calls]], and [[List of yaku|yaku]] are inherently the same. Rule differences are generally applicable using ari (on) or nashi (off) on various rule settings and variations. Any major differences are listed. | |||
