Some sets of tiles can be use as puzzles, in which you have to arrange the tiles so that the edges match in colour, thus forming coloured lines or even loops.

Optimal solutions for Rubik's Cube A computer graphic of a scrambled Rubik's Cube There are two common ways to measure the length of a solution. The first is to count the number of quarter turns. Rubik's Triamid This puzzle is a triangular pyramid of 10 odd shaped coloured pieces (actually they are truncated rhombic dodecahedra) which are held together using 4 small cubical connectors. A move consists of pulling off a small pyramid of 4 pieces, and replacing it in any orientation. The pieces have 4 faces (3 adjacent faces of the rhombic dodecahedron) which have one of four colours. For any pair of colours there is a piece with two faces of each colour.

Tangle (mathematics) In mathematics, a tangle can mean one of two related concepts: The balance of this article discusses Conway's sense of tangles; for the link theory sense, see that article. Two n-tangles are considered equivalent if there is an ambient isotopy of one tangle to the other keeping the boundary of the 3-ball fixed. Hive at Hive is a boardless board game played with Hex tiles. The structure of the game is a fairly traditional chess-like game, overlaid with an insect. theme.

The Mathematical Tourist: Oval Track Puzzles The puzzle known as TopSpin consists of 20 circular pieces, numbered 1 to 20, filling and sliding along an oval track. TopSpin was introduced by ThinkFun (formerly Binary Arts) in 1988. Pieces can be moved around the track in either direction, keeping their order. Or any four consecutive pieces can be maneuvered into reverse order. App Review: Tantrix Strategy connects luck and strategy The beautiful Tantrix Strategy game app [US$2.99] is an example of why it's sometimes good to wait for the second or third version of an iPad app before plunking down your money in the App Store. We're reviewing Version 1.1 here, and it improves on the original with an AI opponent (three levels). This is a huge boost, and it turns a so-so app into something all strategy gamers will want to at least look at. If you just want to dive in and check it out yourself right now, there is a free "lite" version of the app available here.
