QiYi DNA 3x3 Concave

QiYi DNA 3x3 Concave

QiYi DNA 3x3 Concave stands out mainly for its looks. Inside, it runs a regular 3x3 mechanism; only the exterior is unusual. Every piece has an openwork lattice pattern, and the faces are concave. After solving flat, solid cubes for a long time, this shape feels clearly different in your hands and stands out on the shelf. QiYi released this model in 2019. The cube is non-magnetic and comes in a stickerless bright version.

How it turns

It may look like a novelty, but it turns better than its appearance suggests. Users describe it as light and fairly snappy, and the mechanism feels rather solidly built. It is not suitable for speedcubing, though. Corner cutting is weak, so lockups happen easily when the layers are not aligned precisely. When you keep the layers aligned, the turns are pleasant and predictable. A few people mention that a corner popped out during harder turning. It can usually be put back in without any trouble, but it's better to turn this cube calmly. The concave faces and openwork pieces feel different from a regular cube, so it takes a moment to get used to.

Concave or Plane?

The DNA series comes in two versions. They share the same lattice pattern and differ only in the shape of the faces. Plane has flat faces, while Concave, this version, has slightly concave faces. This gives it a more three-dimensional look, and you can feel the distinctive profile in your hand. The choice mainly comes down to which shape you like more.

Who is it for?

Above all for collectors and anyone looking for a cube that is more visually interesting than a standard 3x3. It also works well for relaxed solving, making patterns or as a gift for someone who enjoys puzzles. For breaking records, it's better to choose a typical speedcube, ideally a magnetic one.
