Arrange the ten pieces by breaking them into two groups and putting them back together again.
The Rubik's Triamid is not technically a "twisty puzzle," but it was given the Rubik name. The Triamid consists of ten pieces and six cube-like connectors which hold them together into a tetrahedral shape. The idea is to pull the pyramid apart into two parts, one having six pieces and three connectors and one being the remaining four pieces in a smaller pyramid, then reorient the pyramid in one of eleven ways (twelve, if you count doing nothing for the sake of mathematical completeness).
One of the key features that makes the Triamid difficult to the untrained solver is the fact that about a third of the pieces' sides cannot be seen on a solved orientation because they are on the inside of the Triamid. Thus, you will see many colors that aren't important. To solve it, you must recognize which pieces are corners and which are edges, and then put the corners in their places, after which you can solve the edges. Because of its versatility in moves, the Triamid can be solved from any beginning position.
1990 matchbox began distributing this puzzle, images 4-6.
Around the same time there has been the same box but being sold by Western Publishing under their "Golden" brand. See image 16.
1993 followed a version distributed by Parker Brothers which one year before was bought by Hasbro.
There also is a version by Oddzon (an imprint by Hasbro) and another even later version from Winning Moves.
The original version was part of a series of four puzzles, collectively marketed as Rubik's 90 Collection. The three other puzzles were:
Rubik's Tangle (in four versions)
The Parker Brothers version obviously was part of a series of five puzzles:
There is a separate entry for later versions.
