Uwe Mèffert
Uwe Mèffert (28 November 1939–30 April 2022) was a German puzzle designer and inventor. He manufactured and sold mechanical puzzles in the style of Rubik's Cube since the Cube craze of the 1980s. His first design was the Pyraminx – which he had developed before the original Rubik's Cube was invented. He created his own puzzle company and helped bring to market the Megaminx, Skewb, Skewb Diamond and many other puzzles. Puzzle history Invention of the Pyraminx In the early 1970s, Mèffert was interested in whether pyramids, cubes and other shapes might influence one's health and bio-energy flows. Mèffert constructed balsa wood polyhedra and found the gentle stroking of the apexes of the various shapes had a gentle massaging and stimulating influence and instilled a sense of peace, relaxation, and calm. After playing around with this idea for a while, he cut the solids into symmetric slices and attached them with rubber bands to a center ball. With the aid of his brother (an e ...

Pyraminx Solved
The Pyraminx () is a regular tetrahedron puzzle in the style of Rubik's Cube. It was made and patented by Uwe Mèffert after the original 3 layered Rubik's Cube by Ernő Rubik, and introduced by Tomy Toys of Japan (then the 3rd largest toy company in the world) in 1981. Description The Pyraminx was first conceived by Mèffert in 1970. He did nothing with his design until 1981 when he first brought it to Hong Kong for production. Uwe is fond of saying had it not been for Ernő Rubik's invention of the cube, his Pyraminx would have never been produced. The Pyraminx is a puzzle in the shape of a regular tetrahedron, divided into 4 axial pieces, 6 edge pieces, and 4 trivial tips. It can be twisted along its cuts to permute its pieces. The axial pieces are octahedral in shape, although this is not immediately obvious, and can only rotate around the axis they are attached to. The 6 edge pieces can be freely permuted. The trivial tips are so called because they can be twisted in ...

The Luoshu appears in myths concerning the invention of writing by Cangjie and other culture heroes. It is a unique normal magic square of order three. It is usually paired with the River Map or Hetunamed in reference to the Yellow Riverand used with the River Map in various contexts involving Chinese geomancy, numerology, philosophy, and early natural science. Traditions The Lo Shu is part of the legacy of ancient Chinese mathematical and divinity (cf. the I Ching ) traditions, and is an important emblem in '' Feng Shui'' ()—the art of geomancy concerned with the placement of objects in relation to the flow of qi (), or "natural energy". History A Chinese legend concerning the pre-historic Emperor Yu () tells of the Lo Shu, often in connection with the ''Yellow River Map'' (Hetu) and the eight trigrams. In ancient China there i ...

Toy Inventors
A toy or plaything is an object that is used primarily to provide entertainment. Simple examples include Toy block, toy blocks, Board game, board games, and Doll, dolls. Toys are often designed for use by children, although many are designed specifically for adults and pets. Toys can provide utilitarian benefits, including physical exercise, cultural awareness, or academic education. Additionally, utilitarian objects, especially those which are no longer needed for their original purpose, can be used as toys. Examples include children building a fort with empty cereal boxes and tissue paper spools, or a toddler playing with a broken TV remote control. The term "toy" can also be used to refer to utilitarian objects purchased for enjoyment rather than need, or for expensive necessities for which a large fraction of the cost represents its ability to provide enjoyment to the owner, such as luxury cars, high-end motorcycles, gaming computers, and flagship smartphones.

Puzzle Designers
A puzzle is a game, problem, or toy that tests a person's ingenuity or knowledge. In a puzzle, the solver is expected to put pieces together ( or take them apart) in a logical way, in order to arrive at the correct or fun solution of the puzzle. There are different genres of puzzles, such as crossword puzzles, word-search puzzles, number puzzles, relational puzzles, and logic puzzles. The academic study of puzzles is called enigmatology. Puzzles are often created to be a form of entertainment but they can also arise from serious mathematical or logical problems. In such cases, their solution may be a significant contribution to mathematical research. Etymology The ''Oxford English Dictionary'' dates the word ''puzzle'' (as a verb) to the end of the 16th century. Its earliest use documented in the ''OED'' was in a book titled ''The Voyage of Robert Dudley...to the West Indies, 1594–95, narrated by Capt. Wyatt, by himself, and by Abram Kendall, master'' (published circa 1595). ...
