3D Brainstorm

Published in the book Brainteasers For The BBC And Electron Computers, published by Phoenix Publishing Associates.

The book contains the following description:

If you feel like some brainstorming, how about this three-dimensional game for two players. It is like three-dimensional noughts and crosses, except it has the advantage that all faces can be seen at a glance. Nine cubes are displayed on the screen and each face of each cube is divided into nine squares. Your aim is to colour in a row or column of squares in which you have coloured in the same square. For example, in the screen show above, the red player has coloured in a row of squares on the top left hand cube. Also the yellow player has coloured in all the top left-hand squares on the faces on the front of the central cube, so he has both a row and column of squares coloured in.
