Manufacturer of the type-B and type-F 3x3x3 cubes.

=== Type-B ===
[http://cube4you.com/index.php?gOo=goods_search_list.dwt&gcat=31&gtype= Type B cubes] are the worst cubes for speedcubing. Oddly enough, many of the more 'exotic' cube colors are of this type, such as transparent cubes.

=== Type-F I ===
[[Image:Type-f.jpg|thumb|Type-F I]]

[http://cube4you.com/index.php?gOo=goods_search_list.dwt&gkey=%28f%29 Type F cubes] are different in that instead of having caps on the inside of the pieces (as all cube pieces are hollow) they have caps on the OUTSIDE so as to keep the rubbing surfaces as smooth as possible. Unfortunately, the core is of bad quality, and deteriorates quickly after lubing. It can be replaced with an A core and improved. Type F cubes often considered to be the smoothest cubes on the market. They turn relatively fast and are used by some speedcubers.

=== Type-F II ===
Type-F II cubes are widely considered to be similar in turning quality to the Type-F, but without the drawbacks of [[Core]] deterioration. Many cubers use this cube. The cube has the curious characteristic of slightly rounded cubies and edges that are truncated and capped. The rounded cubies cause average 3x3 stickers to be just under 1mm too small. This cause tiles to extend out from the cubies a little. The truncated edges are presumably to reduce friction in the cube and prevent the edges interfering with the core. This cube is quite light compared to other cubes, which coupled with the smooth turning gives the cube a delicate feel.

Under the correct tensioning this cube can cut 3/4 of the centre piece with minimal effort and without popping.

Rubik's 360

2009-07-29T08:52:10Z

Muesli: /* Summary */

The Rubik's 360 is an obscure puzzle that was released February 5th, 2009. It is a mechanical puzzle that resembles a transparent sphere with one hole, trapped inside a transparant sphere with two holes trapped inside a sphere with 6 different coloured hollow domes protuding from the surface and two black knobs on the sides to operate a turning mechanism. The object of the Rubik's 360 is to get each of the six different coloured balls (red, orange, yellow, blue, white and green) contained in the centre-sphere into it's corresponding colour dome on the outer-sphere. The domes are set on two seperate hemispheres, three on each.

== Construction ==

The middle sphere is weighted deliberatley to cause the escape hole to rest at the top of the sphere, thus creating the logic problem of how to get the coloured balls out of the sphere. This sphere is attatched with two offset struts to the intermittant-sphere. The intermittant-sphere is similary weighted to the middle sphere, causing the holes to rest at the top. This sphere has two offset holes, each corresponding to a hemisphere of domes.

The gaps between the spheres are not wide enough to allow the balls to fit inbetween, thus to solve the puzzle you need to "carry" the balls around each sphere and "pass" the balls inbetween the holes in the spheres. This puzzle is particular notorious for you succeeding in getting a ball to the outer sphere only for it to be in the wrong hemisphere, as passing the balls inbetween the two seperate hemispheres requires you to return the ball to the middle and try again.

An infuriating property of this puzzle is that you can be as careful as you like, but you may still go past a balancing point, the inner spheres will swing freely for one second and the ball you have been toiling over falls back into the middle.

== Summary ==

The Rubik's 360 is different from most other puzzles because there are no applicable algorithms and the puzzle may be solved just with random shaking, although that is unlikely. This puzzle requires much less thought than any twisty puzzle and is more of of a manual-dexterity puzzle than a thought puzzle, in that respect it resembles the Rubik's Magic.

Parity

Muesli: /* Flipped Edge parity */

Parity is a case that may occur (in some form) on all current cubes larger than the 3x3x3 and many other different puzzles, such as the [[Square-1]].

A parity is where two or more seperate pieces are either correctly orientated, but not correctly permuted or correctly permuted but not correctly orientated.

==Parity Cases==

''''USING THE CAGE METHOD AVOIDS THESE PARITIES. THESE PARITY ALGORITHMS ARE ONLY FOR THE REDUCTION METHOD FOR BIG CUBES''''
==Flipped Edge parity==
On even cubes,([[4x4x4]] and [[6x6x6]]) the first type of Parity that may come up is the Flipped-edge parity. This is where two (or three) edge pieces (equivalent to one edge on the 3x3x3) are flipped. (This parity cannot occur on a 3x3x3 unless a piece is removed and replaced the wrong way around). This parity is easy to identify by immediately after the F2L instead of either a no edges, two edges, or the entire cross orientated there is either one or three edges orientated correctly.

This parity may also occur in the [[7x7x7]] V-cube and the 5x5x5 puzzle whilst trying to aquire the last two edges. On these cubes the Parity is identifiable by all edges being solved apart from one or two, both of which have all the correct pieces in the correct edge, but flipped the wrong way around. There is only one case of this on the 5x5x5 but three different cases on the 7x7x7, all of which are solved the same way. It is important to take note that on the 7x7x7 cube only the incorrectly flipped edge pieces should be included in the algorithm. This may require slicing the cube.

It is solved on the 4x4x4/6x6x6 with this algorithm, performed immediately after the Parity is identified.

''''(R*2 B2 U2) (L* U2 R'* U2) (R* U2 F2 R*) (F2 L'* B2) R*2''''

(For the 6x6x6 R*2 represents moving all three slices on the right side 180 degrees.)

Afterwards, the cube is solved normally.

==Switched Edge Parity==

This parity ONLY occurs on even cubes, (4x4x4 and 6x6x6). This parity is where the entire cube is solved besides two edges, which are not permuted correctly. This parity can be first easliy spotted by there being only two unpermuted edges before performing the last 2-look PLL algorithm.

It is solved on the 4x4x4 with this algorithm,

''''(r2 U2) (r2 U*2) (r2 U*2 U2)''''

On the 6x6x6 cube you can use the same algorithm, although here is a clearer version.

''''(3r2 R2 U2) (3r2 R2 3u2) (3r2 R2 3u2 U2)''''

Please note that 3r2 means that you turn all three slices on the right side 180 degrees. Similarly with the 3u2 parts.

==Switched Corner parity==

This parity can only occur, to my knowledge, with the Begginners method. After solving the centres and edges using the begginners method for solving the "reduced" 3x3x3 can come up with this parity. It is where two corners on the cube are incorrectly permuted. This parity is actually a variation of the Switched Edge parity. Because the beginners method requires you to permute the edges BEFORE the corners it causes the corners to be incorrect, so in theory this parity is no different from the previous one. Aside from that, here is the algorithm to fix the two different cases of this parity.

Diagonal corner switched.

''''U*2 L*2, U2, l2, U2, L*2, U*2, R, U', L, U2, R', U, R, L', U', L, U2, R', U, L', U''''

Adjacent corner switched.

''''U*2, L*2, U2, l2, U2, L*2, U*2 F', U', F, U, F, R', F2, U, F, U, F', U', F, R''''

It is important to note that these parity cases are completly avoidable using any technique that uses an OLL/PLL that orients the top layer before permuting the edges.

==Other Puzzles==

Parity can occur on many, many different puzzles. The [[Square-1]], for example can come up with a parity case that requires a large number of moves to solve.
