Cubic Circular

The Cubic Circular magazine was written and produced by David Singmaster in the early Eighties. The first issue was a small 16 page pink booklet, of about 19.5 × 14cm. Later issues were on yellow paper and slightly larger at 21 × 14.5cm (A5 format). There were only 5 magazines published, of which 3 were double issues:

Cubic Circular
Issue 1:16 pagesAutumn 1981
Issue 2:16 pagesSpring 1982
Issue 3 & 4:     36 pages     Spring & Summer 1982
Issue 5 & 6:28 pagesAutumn & Winter 1982
Issue 7 & 8:48 pagesSummer 1985

David Singmaster still has copies of the Cubic Circular available, so I highly recommend acquiring them from him directly, as they are collectible items. David can be contacted via e-mail (zingmast at sbu.ac.uk) or at:

United Kingdom

You can also get them from the Village Games shop in Camden Lock, London.

David Singmaster has very kindly allowed me to reproduce the magazines on this site. I have tried to keep it as close to the original as possible, so I have kept the images in the same style (even though most pictures have been redrawn) and kept the same page numbering. A sheet with corrections was included with the first issue, pertaining mostly to the article about Ernő Rubik, so I have inserted it at that point. I have occasionally inserted a comment or correction of my own, and to be clearly distinguishable from David's original text my comments are in italics and in square brackets,
[like this - J ].

Below are the Tables of Contents. All page numbers are links, as well as the buttons.
