I've been going back through my
It was how to play a game of four-in-a-row (usually known as Connect 4), entirely in one dimension. Two dimensional Connect Four is quite common, and many coffee tables have a set of three-dimensional four-in-a-row, and I have even seen a version of the game played in four dimensions, but the one-dimensional version seems to be totally absent from stores and the internet.
According to my scribbled notes to accompany the sheet, the original article was by Angus Lavery in Games and Puzzles magazine, in 1994. It was created as about a quick game to play with loose counters, but I decided to make a coffee-table version that also automatically re-groups the counters for you.
(Unfortunately, I did not keep the original magazine page, so the above is all the information I have. I have tried searching the internet for Mr Lavery, to no avail. If you know Mr Lavery, or you are Mr Lavery, please get in touch so I can make sure he's OK with this Instructable.)
