''This page is about the [[Gear Cube]] puzzle. For the Gear Cube Extreme or the Anisotropic Gear Cube, see [[Gear Cube Extreme]]. For a list of geared puzzles, see [[:Category:Geared puzzles]].''

The '''Gear Cube''' (also known as the '''Caution Cube''') is a twistable [[puzzle]] in the shape of a [[cube]] that is cut two times along each of three axes, as a [[3x3x3]]. Moreover, there are geared [[edge]]s. That means the edges can turn around themselves. It was  invented by [[Oskar van Deventer]] (idea of [[Bram Cohen]]). It was first produced by [[Shapeways]] since 2009, and then by [[Meffert's]] since 2010 (for 36€) and it finally got copied by [[LanLan]].

This puzzle has 6 fixed [[center]]s (they can't move related to each others), 12 [[edge]]s, and 8 [[corner]]s, and a total of 41,472 positions. It has been proven that every position can be solved in 8 or fewer moves in [[ATM]] and 12 or fewer in [[HTM]]. It's important to note that quarter moves block the cube (only half turns are unprohibited) so [[QTM]] has no meaning for this puzzle.

It's not an official event in WCA competition.

The current unofficial [[world record]] single speed solve is 2.16 seconds held by [[Kentaro Nishi]]. It looks harder but it is actually way easier to solve as compared as with a normal [[3x3x3]] cube.

== Fun facts ==
* The gear cube was originally called the "Caution Cube" because the solver's fingers could get caught in the gears
