I was one of the many people who tried (without success) to solve a 3x3x3 cube in the early 1980's.
I enjoyed it alot then, but lost interest by early 1982. And by 2007, I had forgotten that these "toys" even existed and all the few algorithms
I had learned in 1981 until some coverage of the 2007 World Titles on a mainstream TV network. I brought a storebrought Rukik's 3x3x3
not long later and tried to solve it without any success.
Then I forgot all about again and then in May 2009, I brought a book on Ebay that my parents brought for me
back in 1981 to solve the 3x3x3 cube. Then I used it for a second time, and to my amazement I had solved a Rukik's 3x3x3 cube.
All I did wrong back in 1981 was to confuse the directions for D and D'. Apart from that, I did well then.
NOTE
If you look on places like Ebay, you can buy many books various people put out to solve the 3x3x3 cube and other puzzles
known in the era of the 1980's (ie pyraminx, megaminx, Rubik's domino, Whip It, etc). As there was no internet around then,
these books were of great value. And are a good reminder of how far we've come since then.
