DianSheng SMC 7x7 (56mm + Core-Magnetic)

DianSheng SMC 7x7 56 mm with Core Magnets

This is a 7x7 the size of a regular 3x3. SMC stands for Super Mini Cube. The DianSheng SMC 7x7 measures 56 mm, the same as a typical speedcubing 3x3 cube. Distributors describe it as the smallest mass-produced 7x7 cube. This version is magnetic. It has magnets between the pieces, plus magnets in the core (Core-Magnetic) that pull the corners towards the centre of the cube. The plastic comes in stickerless bright colours, and the internals are in primary colours (Primary Internals).

How does a mini 7x7 turn?

Seven layers fit into 56 mm, so the pieces are very small. Because of this, the cube needs more precise turning than a full-size 7x7. Users praise its smooth feel and the fact that the whole cube fits in one hand. The magnets clearly snap the layers into place, so the cube feels controllable rather than loose. The mechanism is also designed to reduce popping and lockups.

Reviews also mention some downsides. Corner cutting on the inner layers is rather modest. With heavy use, the caps can come off. The small pieces make fast timed solving harder. It's better to know this before you buy than to be disappointed after your first solves.

Magnets and design

• Core Magnets: magnets in the core pull the corners towards the centre. They stabilise the cube and help align the layers.
• Edge-corner magnets: classic magnets between the pieces that give a noticeable "click" when a layer lines up.
• Magnet capsules: keep the magnets in place.
• Stickerless: the colours are in the plastic, so there are no stickers to wear off.

SMC or a full-size 7x7?

The standard DianSheng 7x7 M measures approx. 67 mm and weighs approx. 185 g. The SMC is more than a centimetre smaller and roughly 50 g lighter. It fits in a jacket pocket or a pencil case, and in your hands it feels like a 3x3. However, a larger cube makes a secure grip and high TPS easier. That's why most cubers choose full-size 7x7 cubes for timed practice.

Who is it for?

For those who can already solve big cubes (e.g. 4x4 or 5x5 using the reduction method) and want to have a 7x7 with them at all times. It will also appeal to collectors of miniature puzzles and to people with smaller hands who find standard 7x7 cubes too big. For your first 7x7 for timed solving, the classic size is the more sensible choice.
