Sup! I'm here to provide you with links to read the entire manga of Yugioh, which includes the original 7 volumes and then the duelist arc ending with the millenium arc.
Now then the links here in order:
1.)The original 7 volumes which has yugi and his friends play different shadow games! (note that this isnt about duel monsters and its more about random games. They only play duel monsters 3 times until it becomes a mainstay in the series. Also the character art changes to the ones you know and love at around chapter 15 or so, so yeah enjoy, but keep in mind its quite darker than what you are used to in ygo)
