Taken from Qbic toys homepage:

Played by 2 players or 2 teams, each taking a turn to fill one of 27 potential spaces in a 3x3x3 cube.

The placeholders are represented by balls, normally 14 black and 13 orange.

The objective is to place 3 balls of the same colour in a row or column scoring a point for each unique vertical, horizontal or diagonal row (including internally through the cube)

QbicZu is won by the player achieving the MOST “3 in a row” and not simply the first “3 in a row” .
