Why cant i find more than fist 59 chapters on the manga?

[KyuubiAhri]

I searched online everywhere but couldnt find. Only till their battle against Bakura in that ultimate rpg in his apartment.

 

[Papasmurf]

Because Viz divided the rest of the series into YGO: Duelist and YGO: Millennium World. Search those series as well on other sites.
