BCDM: ONEWA's Disc Mark: The Great Disk of Po-Metru appears on the Mini CD-ROM included with the European TOA ONEWA set. The disc contains the same program, with some minor differences, that you can download from the KANOKA Club if you have entered a code from a ONEWA KANOKA Card.
The adventure follows TOA ONEWA as he seeks the MATORAN AHKMOU. As you would expect, there is an "8-puzzle" and Pick-Up Sticks in this game. It does have a unique twist on the "one-in-twenty-seven" code. This time, you can choose which objects to place in whichever shelves best fit them.
