The player needs to match 3 identical or more tiles in a row (horizontally, vertically or diagonally), as long they match each other, based on Sega's Columns rules, as the Hexa is a clone of it. As the player progresses, various naked Asian women appear in the background (one at a time). ~ Taken from the Bootleg Games Wiki - this seems very strange to be on a device advertised for kids (!?!?!).
