I used to have a set that had magnets inside that would repel each other unless the cubes were in the solved configuration. Anyone know anything about this?
this question from eric osman at rcn dot com 17-feb-2014 : The article says "there is an edge between two vertices if the two colors are on the opposite sides of the cube" . Shouldn't that say "both cubes" or something else ? As written, it is confusing to me, because the two vertices can come from two different cubes, so which of those two cubes are you talking about when you say "the cube" ?
No, it should say "the cube" since the two colors are on opposing sides of this one cube under current evaluation. Other cubes may have the same exact colors on respective opposing sides also, in which case they will add similar paths to the master graph. Thus in the master graph there my be either: 1. No lines connecting two color nodes (meaning no cubes have these colors in opposing sides), or 2. Only one (numbered) line (meaning there is only one cube with such opposing colors, and the line number corresponds to that cube's number), or 3. More than one (mumbered) line (meaning that there are more than one cube with the corresponding opposing colors,and each contributes a numbered line that connects the two colored nodes).

The text says "The puzzles use a subset of the 30 cubes devised by Percy Alexander MacMahon", but this is incorrect; each of MacMahon's cubes is six-colored. They don't seem to be related at all, except for both puzzles having cubes with the faces colored. I'm removing that line. Joule36e5 (talk) 07:55, 30 June 2015 (UTC)[reply]

I have several sets of these cubes, some nearly 50 years old, but none of them are called "Instant Insanity" -- they are all called "Devil's Dice". The cubes are made of wood, and painted.
"Instant Insanity" is the name that Parker Brothers gave to their plastic version of the puzzle in 1967. but this puzzle is much older than that, and may stretch back to medeival times. A history section would be in order, and also some mention of the other names which the puzzle has gone by (such as "Devil's Dice"). — Preceding unsigned comment added by 70.89.176.249 (talk) 01:32, 14 March 2020 (UTC)[reply]
