We started collecting Rubik's Cubes when we learned how to solve them during the summer of 2013. We were interested in learning how because we thought it would be cool to know how to solve a Rubik's Cube, which has about 43 quintillion possible combinations.
There's a variety brands of cubes. In our opinion, the fastest 3x3 out there is the Dayan Zhanchi (dayancube.com). There's also a variety of different sizes, such as a 2x2 Rubik's Cube. The two fastest 2x2s, we believe are the Dayan 2x2 and the WitTwo. There's also a 4x4-11x11. We recommend Shengshou as the brand for all these higher-order cubes. Oskar van Deventer (check
out his website: oskarvandeventer.nl) actually invented a record-breaking 17x17 Rubik's Cube, too. There also are other puzzles, such as the Clock, Square 1, and more. We have a lot of cubes in our collection. We have 2x2s, 3x3s, 4x4s, a 5x5, Pyraminxes, which are in the shape of a pyramid, a Megaminx, which is a dodecahedron, and some Shape Shifting puzzles, which change shape as you scramble them. We can solve a 2x2 in about 10 seconds. We usually get times for the 3x3 between 30 seconds and 1 minute. We can solve a Pyraminx in about 30 seconds. We can also solve something called the Gear Shift. We can also solve the Void Cube, which is a 3x3 with no center pieces, so you don't know which side should be what color. There also are different colors than a regular Rubik's Cube.
As you can see, we like to collect and are very interested in Rubik's Cubes. Watch us in action! We had a Rubik's Cube classroom challenge.
