In-reply-to: RP's message of 31 JUL 1980 1431-EDT To: RP at MIT-MC (Richard Pavelle) cc: CUBE-LOVERS at MIT-MC 2) Another TRUE story of rubiking: The May Company department stores in the Los Angeles area held contests at four of their stores when they started carrying the cube, a couple of months ago. The object was to solve one face in three minutes with their scrambled cube. Reward was a 50 buck gift certificate. They allowed about 6 people every fifteen minutes to enter for two days. The store where I won (and my 10 year old daughter, my wife, and three of my next door neighbors) had 21 winners. I assume the other three stores had similar numbers. They also gave away lots of cube tee shirts for "good tries". I got my cube the night before the contest. But it took me another month to solve the whole thing. I might have worked faster at it if the megabuck prize had been offered. But then you all would have also. 4) Singmaster (edition 4, p. 34) reports on the Rubik domino (2x3x3 cubies), and says each cubie has spots like a domino (1 up to 9). They are to be lined up in numeric order. Top and bottom (the 3x3 faces) are two different colors. Unfortunately, Singmaster laments, magic square type patterns (all directions add to same number) are not possible, since all edges are even, all corners odd. The mechanics of the device are said to be "more complicated than for the Magic Cube." /Don Lynn
