FanXin Puzzle 3x3x4 Cube

FanXin Puzzle 3x3x4 Cube

FanXin 3x3x4 is a cuboid, a puzzle shaped like a rectangular box. The top and bottom have a 3x3 layout, and there are four layers in height. It's a gentle introduction to cuboids for anyone who can already solve a regular 3x3 and wants to try something different. It's an affordable, simple model in a stickerless version with bright colours.

How it differs from a regular 3x3

The top and bottom faces turn normally, by 90°. The side faces are rectangular, so they can only be turned by 180°. This limits the number of allowed moves, and the extra layer creates situations you won't see on a classic 3x3, including parity. It has a lot in common with the 3x3 cube, but you'll need to adapt some algorithms or learn new ones. For many people, that's exactly what makes cuboids so interesting.

How it turns

Users praise its smooth turning, low weight and quite good corner cutting for this price range. The most common remarks are that the cube can be noisy and comes dry, without any lube. Straight out of the box, it may feel stiff and catch. Once lubed and with the tension set, it performs noticeably better. Tension is adjusted with screws in the centres, and a regular screwdriver is all you need.

This isn't a cuboid for breaking records. It has a simple mechanism without magnets or advanced adjustment options. As a puzzle for learning and casual solving, it does the job well.

Who is it for?

For people who have already solved a 3x3 cube and want an inexpensive way to find out whether they enjoy cuboids. It also makes a great addition to a collection of unusual puzzles. If you're buying it for a child who is just starting out with cubes, it's better to get a regular 3x3 first, because a cuboid can be discouraging without knowing how to solve a 3x3.
