This is a minimalistic guide for solving 3x3xN cuboids, where N does not equal one or three. Prior knowledge of solving a 3×3 required for higher ordered versions, preferably experience in scrambling/ solving a cube using 180 degree face turns.
Lets start at the beginning with the:
3x3x2 or Domino Cube
Hasbro released a computer game, Rubik’s Games, back in 1999. I remember playing with a computer simulation of the 3x3x2 before playing with a physical version.
The first version I’ve seen of the 3x3x2 was the Domino Cube, released by Rubik in 1983. These rare puzzles would pop up on ebay and fetch $400 back in the 90’s. I picked up my first domino cube in 2005(ish) for $50 as more and more started resurfacing. Unfortunately, now the puzzle is being knocked off and recreated by various vendors.
Back in the late 90’s early 2000’s, a member of the Twisty Puzzles forum posted a cool thread about creating 2x2x3 and 3x3x2 cuboids by attaching regular sized 3×3 pieces to a keychain cube. Many brave puzzle builders jumped on building their own cuboids by hacking their cubes apart, I too attempted to build one but mine didn’t come out all that well and ended up being fragile and falling apart…
But enough history, lets get to solving!
