Pachi-Slot Aruze Ōkoku 6

Pachi-Slot Aruze Ōkoku 6 is a pachi-slot (Japanese slot machine) simulation game featuring three machines made by Aruze: Donchan 2, Dekadonchan 2, and Heracles. It is the first in the series to appear on the PlayStation 2, and also the first to feature fully-3D reproductions of the real-life machines. Included are standard Free and Challenge modes, as well as (now defunct) internet ranking. All three machines feature detailed stat tracking and configuration modes.
